Well Nuts vs Rivets

Well nuts vs rivets are a concern for many business owners. Well nuts and rivets are both commonly used fasteners in industry. For many people, correctly stating the difference between them can be a daunting task. However, we want to show you the differences between weld nuts and rivets in this guide.

We will compare all the important features, applications, advantages and disadvantages. Let’s explore together!

What Are Well Nuts?

Well Nuts consist of a metal nut embedded in a rubber housing. These fasteners are often used for connections on thin sheets, metals, plastics or other materials. It provides a strong connection in environments where vibration, shock, or sealing is required.

What Are Rivets?

Rivet can hold two or more different or identical materials together. Generally, rivets provide a permanent connection. Once properly installed, they are very difficult to remove unless the structure of the rivet is destroyed.

What Are Rivets? Rivmate Rivets Supply

Rivets offer the advantages of high strength, excellent durability and versatility. These characteristics have led to their widespread use in industrial and engineering applications. Rivets are ideal in applications where long-term stability and high reliability are required.

Well Nuts vs Rivets : Installation Methods

There is a significant difference between Well Nuts and Rivets in terms of installation methods.

The installation of Well nuts does not require complicated tools, only bolts and spanners are needed to complete the installation. Installation of well nuts is simple, but requires precise control of the tightening force to avoid excessive compression of the rubber. This can still be difficult.

The installation of rivets is simpler and faster. The operator only needs to use a rivet gun to complete the installation of blind rivets.

Well Nuts vs Rivets: Strength

Common fastener strengths include the following:

Blind Rivet Tensile Strength

In practice, well nuts are more commonly used in low to medium strength applications. While rivets can be used in both low to medium and high strength applications.

Well nuts have a lower pullout strength due to the more limited expansion force provided by the rubberized shell. The shear strength of well nuts is limited by the friction of the rubber.

There are many types of Rivets. Rivets can provide high blind rivet shear strength and blind rivet tensile strength, and since the rivet body expands and extrudes to hold the joint material, the stresses are evenly distributed throughout the joint area.

Well Nuts vs Rivets : Fatigue Performance

Well nuts are made of rubber and nuts. The fatigue properties of rubber can easily and gradually deteriorate under long-term dynamic loading. This leads to a gradual loss of elasticity and strength, ageing, cracking and deformation of the well nuts.

Rivets are usually made of aluminium, steel, stainless steel or other high-strength metals. These materials have excellent fatigue resistance. Metal rivets maintain structural integrity under repeated loads and are less susceptible to fatigue fracture. As a result, Rivets offer greater reliability and durability under dynamic loading.

Differences Between Well Nuts and Rivets in Terms of Applicable Materials

Rivets and well nuts both work well for joining metal materials. The following types are included:

  • Aluminum
  • Carbon Steel
  • Stainless Steel
  • Copper
  • Brass

In addition to metal materials, rivets has an even wider range of joining materials. If your project is to join plastic, wood or composite materials, then you should choose rivets for the joining.

Rivets vs Well Nuts: Cost

The cost of a fastener is evaluated in two main ways.

  1. Cost of materials
  2. Cost of Installation

Well nuts have a higher unit and installation cost.

The price of Rivets is determined by the raw materials used in manufacturing. The raw material is expensive, the price of rivets will be higher. But the installation of rivets is very fast and cheap. Its installation cost is extremely low. Operators can directly install it without training.

Well Nuts vs Rivets: Thickness of the Connection

Well Nuts vs Rivets: Thickness of the Connection

Well nuts are suitable for joining thin materials. If your project has a certain thickness, well nuts may not perform as well.

the grip range of blind rivet

Rivets can be applied to a wide range of material thicknesses. Whether it’s a thin sheet of material or a material with a certain thickness, rivets have a type of rivet that can be matched. For materials of varying thicknesses, rivets of the appropriate length can be selected to accommodate the different thicknesses.

Comparison of Well Nuts and Rivets : Removability

Well nuts provide an excellent connection point for thin sheet connections.Well nuts are a removable, reusable connection. The bolts can be installed and removed several times.

Best Ways to Remove Rivets

Rivets are usually considered permanent connections. Once properly installed, the only way to replace or repair them is through destructive removal. The operator needs to destroy the internal structure of the rivet so that it is rendered completely useless.

Difference in Application Between Rivets and Well Nuts

Well nuts provides excellent shock and water resistance due to the expanded and flexible design of the rubber housing. They are therefore particularly suitable for applications where vibration is to be absorbed, noise is to be minimised and a seal is to be provided. Commonly used well nuts are used in the following applications:

  • Housings or components for electronic equipment
  • Vehicle interior panels, trim strip fixing
  • Outdoor equipment that needs to be sealed or waterproof. Solar devices, weather instruments, etc.

Rivets provide high strength and permanent fixing through mechanical deformation.Rivets are used where long term stability is required and connections cannot be loosened.

Rivets are especially structural due to their unique design. The locking structure is designed to provide long-lasting connection strength even in harsh environments.

Rivets are used in a much wider range of scenarios than well nuts. Whether it is a light application or a heavy application, rivets provide a stable connection. Below are some common application scenarios for rivets.

  • Wing, fuselage sheet metal fixingFixing of bridges
  • building steel structures
  • Assembly of car bodies and chassis

Quick FAQS

There are many types of raw materials used in the manufacture of rivets.Stainless steel rivets will not rust.Carbon steel blind rivets will use some anti-rust measures to prevent the rivets from rusting.

Therefore, if rusting of rivets is a concern for your project, you can choose a rivet material that will not rust. Or use some rust release measures.

Typically, rivets would be considered a permanent connection. Once rivets are properly installed, there is no way to remove them unless the structure of the rivets is damaged.

How to Choose Between Well Nuts or Rivets?

Although well nuts and rivets are used to join thin sheet materials. However, you can choose them correctly by the actual project requirements.

  • Choose Rivets: When you need a high-strength, permanent connection, especially in harsh environmen.s, Rivets is the better choice for industrial and structural applications.
  • Choose Well Nuts: When you need shockproof, waterproof, removable connections and a more complex environment (e.g., needing to seal or accommodate material deformation).Well Nuts are the more appropriate choice for low- to medium-strength applications such as electronics, automotive and outdoor equipment.

Strength of Rivets and Screws - Tensile Strength

The blind rivet tensile strength is an indicator that business owners need to keep an eye on. This ensures that your project is in safe hands.Let’s explore!

Table of Contents

What is the Blind Rivet Tensile Strength?

Tensile Strength is the maximum stress at which a material will resist fracture under tensile force. For blind rivets, this parameter indicates the maximum load that the rivet can withstand when a tensile force is applied, and is usually expressed in megapascals (MPa) or pound force (lbf).

Blind Rivet Tensile Strength

Blind Rivet Tensile Strength is a measure of the ability of a blind rivet to resist tensile stress in its axial direction when joining two pieces of material.

For blind rivet, shear strength and tensile strength are the two most important strength indicators. Qualified tensile strength ensures that the blind rivet will maintain the stability of the connection in practical applications. When business owners buy blind rivets, they basically pay attention to the index of tensile strength.

Factors Affecting the Blind Rivet Tensile Strength

Blind rivet tensile strength is used as one of the important indicators for blind rivets. It is influenced by a number of factors that determine the maximum tensile force that the rivet can withstand in practice. The following are the key factors affecting the blind rivet tensile strength:

1.Material

There are many types of materials used to manufacture blind rivets. Different materials have different inherent strength properties. For example, stainless steel has high tensile strength, while aluminum is lighter but less strong. Monel (nickel-copper alloy) combines high strength with excellent corrosion resistance.

In addition to this, the tensile strength of different grades of the same material (e.g. different contents of carbon steel or different types of stainless steel) can vary significantly.

In general, a larger rivet diameter usually means higher tensile strength. This is because the larger the rivet diameter the more tensile force it can withstand. Smaller diameter rivets are more likely to break under the same amount of tension.

3.Rivet Design

Types of Rivet Heads

Blind rivets are available in three head types: countersunk head, large flange head and round head. Different rivet head designs affect the distribution of forces in the material, which in turn affects the tensile strength of the rivet. Large flange head can better distribute stresses and reduce material deformation, which helps to improve the overall tensile strength.

4. Material Thickness

The tensile strength of blind rivets may be compromised when used in materials that are too thick or too thin. Excessively thick materials may not lock completely, while excessively thin materials may be pulled through or deformed, affecting the reliability of the connection.

5. Surface Treatment

Anti-corrosion coatings: Materials that are susceptible to corrosion, such as carbon steel, are often given a surface treatment (e.g., galvanized or coated). This improves their corrosion resistance and tensile strength. However, improper surface treatment may cause the coating to peel off or the rivet to corrode, reducing tensile strength.

Surface Treatment of Blind Rivet

Anodizing: Aluminum rivets are often anodized to increase their surface hardness and corrosion resistance, which indirectly increases tensile strength.

6. Fatigue and Aging

Blind rivets are subjected to repeated tensile stresses and their tensile strength gradually decreases. Microscopic cracks caused by fatigue may eventually cause the rivet to break.

Over time, certain materials (e.g., plastics or certain metals) may deteriorate. This is resulting in a reduction in the tensile strength of the blind rivet.

Test Methods for Blind Rivet Tensile Strength

Rivmate’s Blind Rivets are tested for tensile strength in accordance with international standards such as ASTM F606/F606M and ISO 14589. These two standards are internationally recognized standards for rivet testing.

General testing of blind rivet tensile strength requires the use of a tensile testing machine and fixtures. This equipment is capable of applying and accurately measuring the maximum tensile strength of a blind rivet before it breaks.

Below are the steps to test the blind rivet tensile strength:

  1. Installation of blind rivets to be tested into the fixture
  2. Start the tensile tester and apply the tensile force slowly and evenly. The speed of application should be in accordance with standard specifications.
  3. A tensile tester will record the maximum tensile force, or tensile strength, at which a rivet breaks. Record the relevant data.

How to Choose the Right Blind Rivet?

1.Material Selection Based on Tensile Strength

The difference in tensile strength of different materials is significant. Therefore choosing the right material can have a direct impact on the strength and durability of the connection. The strength requirements of most projects can be categorized into the following two types:

  1. High Tensile Strength Requirements
  2. Medium Tensile Strength Requirements
Blind Rivet Tensile Strength Machine

Typically projects with high tensile strength requirements will choose higher strength materials. For example, stainless steel blind rivets, carbon steel blind rivets and monel blind rivets. These material types are perfect for providing a stable and secure connection for high strength applications.

Projects with medium tensile strength requirements include electrical connections and lightweight design projects. Such projects typically use aluminum rivets with a good strength-to-weight ratio and copper rivets with good electrical conductivity.

2. Selection of Blind Rivets According to the Actual Application

In actual use, many projects have very strict requirements for blind rivet tensile strength. For example, in construction and structural engineering, blind rivets need to withstand external loads (e.g. wind, vibration, etc.). Then blind rivets need to have high tensile strength, so as to ensure the safety and stability of the structure.

Typical applications for medium tensile strength include the connection of electrical equipment and electronics. These applications do not require high strength, but they do require specific properties of the blind rivet. For example, light weight or extremely high electrical conductivity.

Frequently Asked Questions

1.Why is the Blind Rivet Tensile Strength Important?

Blind rivet tensile strength determines the ability of the rivet to maintain the integrity of the connection when subjected to external forces. In applications where high tensile forces need to be resisted, choosing the right blind rivet tensile strength can prevent joint failure or structural damage.

2.What Applications Require Special Attention to the Tensile Strength of Blind Rivets?

Tensile strength is a factor that must be given special attention when selecting blind rivets for applications such as building structures, aerospace, bridges, heavy machinery and other applications where high stresses and tensile forces need to be applied.

3. What is the Difference Between the Tensile and Shear Strength of Blind Rivets?

Tensile strength measures the ability of a rivet to resist the action of a tensile force. Shear strength, on the other hand, measures the ability of a rivet to resist a shear force, such as two pieces of material sliding against each other. Both parameters are critical for different types of loads.

Conclusion

Blind rivet tensile strength is an important metric for manufacturers to consider when selecting a blind rivet. A blind rivet with the proper tensile strength will ensure that the connections in your project are stable and secure. This will minimize subsequent repairs and result in significant cost savings.

How to Choose Blind Rivets for Soft Materials?

Table of Contents

In the manufacturing and assembly processes, soft materials such as plastics, woods, composite boards, and thin aluminum sheets are widely used in the automotive, home appliance, and construction industries. However, these materials have low density and limited strength, and the use of traditional rivets often leads to “piercing through”, “deformation”, or “connection failure”. How to correctly select and install blind rivets for soft materials? This blog will delve into the key technical points of riveting soft materials to help you find the most suitable low-density fastening solution.

Understanding Soft Materials in Riveting Applications

Soft Materials

In fastening technology, Soft Materials typically refer to substrates with low density, low yield strength, and prone to plastic deformation. Such materials include plastic, wood, aluminum alloy, FRP (fiberglass reinforced plastic), PVC (polyvinyl chloride), and carbon fiber composites, etc.

They have obvious flexibility and compressibility, and are prone to problems such as collapse, deformation or tearing, especially in the concentrated force area of the riveting. Due to the structural characteristics of these materials, the expansion force of traditional metal rivets is often too large, which may damage the surface of the base material or cause stress concentration.

When riveting soft materials, engineers need to strictly control the expansion path and clamping force of the rivets to achieve a secure connection without damaging the material. This is also the key to choosing Blind Rivets specifically designed for soft materials.

Why Standard Blind Rivets Fail in Soft Materials

Types of Peel Type Blind Rivets

When connecting low-density substrates such as plastics, woods or composite materials, traditional Blind Rivets often fail to achieve the desired tightening effect. This is because their structure and load-bearing characteristics are not designed for flexible or compressible materials.

  • The tail is unevenly expanded, which makes it prone to concentrating stress.
    During the self-drilling riveting process of standard rivets, the tail part will undergo axial deformation and expansion. However, in soft substrates, this local expansion will form a “high stress concentration area”, causing the material to “tear” or the surface to collapse.
  • Excessive clamping force or insufficient friction.
    When the rivets exert excessive force on the soft material, the surface of the material is prone to being crushed or undergoing permanent deformation; conversely, if the friction is insufficient, the connection will gradually loosen.
  • The contact area is too small, resulting in uneven force distribution.
    The head and tail of the standard rivet both adopt a “point contact structure”, which limits the supporting area for flexible materials. The lack of sufficient pressure-bearing surfaces leads to the concentration of clamping force, thereby reducing the overall durability and anti-detachment capability.

In soft materials, it is advisable to opt for specific types of rivets that have a large contact surface or a split tail design, such as Peel Type or Large Flange Rivets, in order to distribute the stress and extend the service life of the connection.

Best Blind Rivet Types for Soft Materials

When connecting flexible substrates such as plastic, wood, composite boards or thin aluminum, choosing the appropriate type of Blind Rivet is crucial for ensuring the reliability and durability of the connection. Different types of rivets will affect the distribution of forces, the stability of clamping, and the crack resistance. The following are several high-performance solutions designed by Rivmate for soft materials:

Soft-Grip RivetThe tail forms a “bowl shape” that absorbs deformation stress.Foam boards, plasticsAbsorbs energy, prevents cracking, and protects soft substrates.Rivmate S-Series

In the riveting of soft materials, the contact area and the shape of the tail expansion determine the success or failure of the connection.

  • If the substrate is relatively soft (such as ABS, PVC), it is recommended to use Peel Type or Soft-Grip Rivet.
  • If you want to balance both structural strength and surface integrity, you can choose Large Flange Rivet.
  • For modular production lines or assembly of multi-thickness plates, the Multi-Grip Rivet is preferred to enhance assembly efficiency and reduce inventory.

Material Compatibility for Soft Material Riveting

When choosing a Blind Rivet suitable for soft materials (such as plastic, wood or composite boards), the material compatibility of the rivet itself is of utmost importance. There are issues such as electrochemical reactions, hardness differences, and inconsistent thermal expansion coefficients between different metals. Ignoring these factors may result in corrosion, electrochemical reactions or damage to the substrate.

Rivet MaterialRecommended Base MaterialKey Characteristics & Advantages
AluminumPlastic, wood, aluminum sheetLightweight and corrosion-resistant; no galvanic reaction with aluminum substrates; ideal for soft or delicate surfaces.
Steel (Zinc-Plated)Composites, steel insertsHigh strength and cost-effective; requires protective coating to prevent rust.
Stainless Steel (304 / 316)FRP, PVC, composite panelsExcellent corrosion and fatigue resistance; suitable for humid, coastal, or outdoor environments.
Copper / BrassElectrical components, decorative structuresSuperior electrical conductivity and ductility; ideal for electrical connections and aesthetic applications.
  • For soft or low-density materials (such as plastic and wood), it is recommended to use aluminum rivets or large flange structures to reduce surface indentation and local stress concentration.
  • Avoid using hard materials (such as stainless steel) for direct riveting of flexible substrates, as these rivets may penetrate or damage the surface during the riveting process.
  • In situations requiring stronger support, a backing washer can be added or Rivmate Large Flange Rivets can be used to significantly improve the force distribution.

Proper Installation Techniques for Blind Rivets in Soft Materials

When connecting flexible or low-density materials such as plastic, wood, and composite boards, even if the appropriate type of rivets is selected, improper installation can still lead to material cracking, collapse, or loosening of the connection. The following are the key operational points summarized by the Rivmate engineering team, which can significantly enhance the installation reliability and structural lifespan.

① Hole Size Accuracy

The hole size should be approximately 0.1–0.2mm larger than the diameter of the rivet body. If the holes are too small, the material will be compressed and deformed; if the holes are too large, the clamping force will be reduced and the parts may become loose. It is recommended to use high-precision drill bits or limiting drilling tools to ensure consistency.

Industry applications for zinc plated blind rivets

② Install backing washers

For thinner or softer materials, a Backing Washer should be added on the back side. This component can significantly distribute the tension, preventing the tail of the rivet from “penetrating” or tearing the material.

Rivmate offers compatible gaskets in aluminum, stainless steel and nylon materials.

③ Controlled Speed & Force

10 Rivet Gun Problems and How to Solve

When using pneumatic or electric riveting guns, it is recommended to set lower pulling force and speed. Excessive core shaft stretching can cause local heating and stress concentration of the material, especially in plastic substrates, where it is prone to cracking.

④ Use Anti-Slip Rivet Tools

It is recommended to use the Rivmate electric riveting gun with a torque control system, which can prevent problems such as slipping teeth, uneven pulling force, or unstable rivet rotation. A stable riveting process helps to achieve a consistent expansion form.

⑤ Post-Installation Inspection

After the installation is completed, the following should be checked:

  • Is the tail of the rivet evenly expanded?
  • Is the top part flat and properly fitted?
  • Is there no crack or local collapse on the surface of the base material?

When connecting flexible materials such as plastic, wood or composite boards, even if the appropriate type of rivets is selected, if the installation or selection is improper, problems such as cracks, loosening or failure are prone to occur. The following are the typical problems and improvement methods summarized by the Rivmate engineering team based on thousands of experiments and customer cases:

Question 1: Material Cracking due to Rivet Pulling

Reason Analysis: The tail end of the standard rivet undergoes concentrated expansion, resulting in excessive stress and causing the material to rupture.

Solution: Choose Peel Type Rivet or Large Flange Rivet, as these structures can distribute the pressure and prevent material tearing or surface collapse.

Question 2: Loose Joint or Weak Grip

Reason Analysis: The grip range of the rivet does not match, or there is a significant difference in the thickness of the substrate.

Solution: Switch to Multi-Grip Rivet, which can automatically compensate for thickness variations and maintain a stable clamping force. It is suitable for structures with large assembly tolerances.

Question 3: Backside Collapse or Pull-Through

Reason Analysis: Lack of supporting surface. During riveting, the tail end is directly pressed into the soft substrate.

Solution: Add a Backing Washer on the back, or use a Soft-Grip Rivet, with the “cup-shaped” design at the tail to buffer stress and prevent the structure from loosening.

FAQ

Sure, but you need to choose the models specifically designed for soft substrates. For example, Rivmate’s P-Series Splitting Bolts or L-Series Large Flange Bolts. They can distribute the stress and prevent the material from being pulled apart or crushed.

Q2: How do I prevent rivets from cracking soft materials?

The key lies in controlling the installation force and choosing the appropriate structure. By using low-speed riveting tools, adding backing washers, or adopting Soft-Grip type rivets, stress concentration and thermal deformation can be effectively reduced.

Q3: Which rivet type is best for PVC or FRP panels?

It is recommended to use Peel Type Rivet or Multi-Grip Rivet. These types of rivets can form a wide tail support surface in composite boards and plastic structures, preventing the separation of board layers and providing a stronger connection.

Q4: Are large flange rivets stronger for soft materials?

Yes. The large flange design can significantly increase the force-bearing area, reducing the risks of local indentation and tearing.

Q5: Do I need washers when riveting soft materials?

It is recommended to use. The gasket can distribute the stress on the back, preventing the head of the rivet from “getting stuck” or being pulled through. Rivmate offers Backing Washer in various materials such as aluminum, stainless steel, and nylon, suitable for different environments and substrate hardness.

Build Strong Connections on Soft Materials

In soft materials such as plastic, wood or composite boards, the key to connection is not “higher strength”, but “better structural fit”. By choosing blind rivets with wide contact surface (Large Flange), flexible tail (Peel or Soft-Grip Design) and appropriate gripping range (Correct Grip Range), it is possible to effectively prevent material rupture, stress concentration and long-term loosening, thus achieving safe and reliable permanent fixation.

Types of Blind Rivet Mandrel

Blind rivet mandrel is an important part of the blind rivet. This article will explain to you the importance of the blind rivet mandrel and everything you should know about it.

Table of Contents

What is the Mandrel on a Blind Rivet?

The Blind Rivet Mandrels are part of the Blind Rivet and is a very critical component in the rivet installation process. Blind rivets typically consist of two parts: the body of the rivet (usually hollow) and the blind rivet mandrel. The Mandrel runs through the body of the rivet and plays a key role in the installation process.

Blind Rivet Mandrel

When installing blind rivets, a riveting tool is used to pull the blind rivet mandrels so that the rivet body of the blind rivet can expand to form a stable connection. Therefore, the design and performance of the blind rivet mandrels will have a direct impact on the installation of the blind rivet, the strength of the connection and the overall reliability.

What Are the Benefits of a Blind Rivet Mandrel?

In the working principle of the Blind Rivet, the normal expansion of the rivet body is driven by the Blind rivet mandrels.Blind rivet mandrels are the core component of the Blind Rivet in the riveting process, which directly affects the installation of the Blind Rivet. The following are the main roles of the blind rivet mandrels in a blind rivet.

1. Expansion Rivet Body

Blind rivets are typically installed using a specialised rivet gun. During the installation process, the operator will use the rivet gun to pull the blind rivet mandrel through the end of the rivet body. This process causes the end of the rivet body to expand, forming a mushroom or similar shape, which secures the rivet in the material.

How to Install Pop Rivets? - Pull the Mandrel Until it Breaks

The proper blind rivet mandrels ensure that the rivet expands correctly within the material to form a solid joint. Without the pull of the mandrel, the rivet cannot expand and an effective riveted joint cannot be achieved.

2. Forming a Strong Connection

The blind rivet mandrels are pulled as the rivet body expands. The greater the force pulling the mandrel, the more uniformly the blind rivet will blind rivet expand and the stronger the connection will be.

3. Auto-Break Ensures Consistent Installation

A blind rivet has a special design. When the mandrel is pulled to a certain predetermined tension, it automatically breaks at a specific location. This unique design ensures that every rivet is installed in the same manner and with the same force.

4. Provides Additional Strength Support

Magna Lok Rivets for Sale - Bulk Huck Magna Lok Blind Rivets Wholesale

During installation of structural blind rivets, a portion of the mandrel remains in the rivet body after breakage. This design enhances the pulloutq and shear strength of the blind rivet.

In practice, applications such as those requiring high load capacity choose to use these blind rivets.

Types of Blind Rivet Mandrel

There are many types of blind rivet mandrels depending on the actual application.

Material

There are several common metal blind rivet mandrels:

  • Aluminum Mandrel
  • Steel Mandrel
  • Stainless Steel Mandrel
  • Copper Mandrel

Application

There are many types of blind rivet mandrels depending on the application requirements and rivet design, each with specific uses and characteristics. Below are a few common types of blind rivet mandrels:

  1. Standard Blind Rivet Mandrel: The most common type. Mandrels break automatically when a specific tensile force is reached and are suitable for light to medium load applications. E.g. joining of sheet metal, plastics and composites.
  2. High-Strength Mandrel: Made from higher strength materials such as high carbon steel or stainless steel. Suitable for high loads and critical structural connections. Such as construction, bridges, aerospace and automotive manufacturing.
  3. Extended Mandrel: The Extended Mandrel is longer than the standard mandrel and is suitable for installation in thicker materials or where deeper embedding is required.
  4. Retained Mandrel: This blind rivet mandrel does not break completely after installation, a portion of the mandrel remains in the rivet body, increasing the shear and pull-out strength of the rivet.
  5. Locking Mandrel: Locking Mandrels have a special design that allows a portion of the mandrel to be locked into the rivet body as the rivet expands. This design increases the stability and strength of the joint and prevents the rivet from loosening.

Structural Rivet vs Blind Rivet : Blind Rivet Mandrel

Although structural rivet is one of the blind rivet. But there are still many differences between them. The differences in the blind rivet mandrels will be explained here.

1. Mandrel Strength and Material

The mandrels of structural rivets are typically made of high-strength materials, such as high-carbon steel or stainless steel.  These mateials are capable of withstanding greater tensile and shear forces. These materials will not break or fail prematurely under high stress conditions.

The mandrels of blind rivets are designed to accommodate general industrial and consumer applications and are not normally subjected to particularly high stresses. For this reason the mandrels of blind rivets are usually made of materials such as mild steel, aluminium or copper, which are sufficient for light duty connections.

2. Mechanism of Breakage of Mandrels

The breakage mechanism of structural rivet mandrels is designed to be very precise. This breakage mechanism ensures that the mandrel breaks after a predetermined tension is reached and a portion of the mandrel remains inside the rivet. This retained portion of the mandrel adds to the overall strength of the rivet.

Sheet Metal Blind Fasteners : A Complete Buying Guide

Blind rivets, on the other hand, have a mandrel that breaks at a predetermined breaking point after the rivet is fully expanded, usually near the head of the rivet.Blind rivet mandrels do not retain much of the mandrel inside the rivet.

3. Applicable Scenes and Design Complexity

Structural rivets are mainly used in construction, aerospace, automotive manufacturing and other application environments that require high strength and reliability. The design of its mandrel is more complex and requires additional structural support for the rivet after breakage.

Whereas, blind rivets are suitable for scenarios such as general industry, consumer products and lightweight structures. Its blind rivet mandrel is relatively simple in structural design. And the main function of its blind rivet mandrel is to ensure rapid expansion and installation of the rivet.

Shear Strength is the ability of a material to resist damage by shear forces (forces parallel to the cross-section of the material). In other words, shear strength is the maximum stress at which a material will resist sliding or breaking when a force is applied parallel to the direction of its cross-section. Shear strength is usually expressed in terms of stress per unit area, and the units commonly used are megapascals (MPa) or pounds per square inch (psi).

Shear Strength

Determination of Shear Strength

Shear strength is usually determined experimentally. In a typical shear test, a sample material is held in a specific testing machine and a gradually increasing shear force is applied until the material breaks. The value of the stress at this point is the shear strength of the material.

The shear strength (τ) is usually calculated by the following equation:

            τ=F/A

  • F is the applied shear force.
  • A is the area of the shear surface.​

What is Blind Rivet Shear Strength?

The shear strength of a blind rivet is an important indicator in assessing the ability of a blind rivet to maintain the integrity of the connection in a given application. Shear strength is something you need to be concerned with if you have a project where the blind rivet will be used in applications that are subjected to high forces or loads that need to be sustained over a long period of time.

Shear Strength of Blind Rivet

Common Range of Shear Strength for Blind Rivets

  • Aluminium Blind Rivets: shear strength typically between 200 and 300 MPa, suitable for light duty applications.
  • Steel Blind Rivets: shear strengths typically between 300 and 400 MPa, suitable for medium duty applications.
  • Stainless Steel Blind Rivets: Higher shear strengths, typically over 400 MPa, for high loads and harsh environments.

Importance of Shear Strength for Blind Rivets

Shear Strength is extremely critical to Blind Rivets. Blind rivets are subjected to shear forces in many applications. Therefore, shear strength has a direct impact on the safety, durability and overall performance of the blind rivet connection. Here’s how important shear strength is to blind rivets:

1. Ensure Connection Strength and Security

The shear strength of a blind rivet determines the maximum shear force it can withstand. If the shear strength is insufficient, the rivet may break or fail during application, causing the connection to loosen or separate.

Best Ways to Remove Rivets

In high stress applications such as automotive or aerospace, blind rivets need to withstand the large shear forces generated during vehicle travel or flight. High shear strength rivets ensure the reliability of the connection and prevent accidents or failures.

2. Accommodate Dynamic and Repetitive Loads

Blind rivets in many applications are subjected to repetitive or dynamic loads such as vibration, shock or mechanical stress. These loads generate repeated shear forces that can cause gradual fatigue or fracture of rivets with low shear strength.

In practical applications, such as in railway, construction and mechanical equipment. Blind rivets are often exposed to constant vibration or dynamic loads. High shear strength rivets maintain the integrity of the joint under these conditions, reducing the risk of fatigue fracture.

3. Extended Service Life

Do Rivets Rust?

Blind rivets with high shear strength are less likely to deform or break during use. This feature extends the life of the joint and reduces the frequency of maintenance and replacement.

For example, in outdoor structures such as bridges, pylons or building facades, the durability of blind rivets is very important. High shear strength rivets ensure that these structures remain stable and safe even after prolonged exposure to environmental stresses.

4. Adaptation to the Connection of a Wide Range of Materials

Different materials require different shear strengths for the connection. The shear strength of a blind rivet must match the strength of the material being joined in order to form a solid connection.

For example, when joining metals to composites, the shear strength of the rivet needs to be high enough to prevent joint failure due to differences in material hardness. Selecting blind rivets with high shear strength can accommodate this type of dissimilar material joining requirement.

Factors Affecting the Blind Rivet Shear Strength

The shear strength of a qualified blind rivet provides the ability to resist fracture or deformation. Shear strength is a key indicator in assessing the suitability of a rivet for a particular application and is influenced by a number of factors. The following are the main factors that determine the shear strength of blind rivets:

1. Material of Blind Rivets

Blind rivets are usually made of aluminium, steel, stainless steel, copper and other materials. The strength of the material itself directly affects the blind rivet shear strength.

  • Aluminium: lightweight but with relatively low shear strength, suitable for light duty applications.
  • Steel: High shear strength for medium to heavy duty applications.
  • Stainless steel: very high shear strength and corrosion resistance for high loads and harsh environments.
  • Copper: good corrosion resistance but low shear strength for specialised environments.
  • Material treatment: The treatment process of the material, such as heat treatment or surface hardening treatment, also affects the shear strength. Proper heat treatment can significantly improve the strength and durability of the material.

2. Rivet Diameter

The larger the diameter of the rivet, the larger the shear area and the higher the shear force it can withstand. Therefore, larger diameter rivets typically have higher shear strength.

3. Rivet Shape and Construction

Different head types of blind rivets affect the shear strength. Blind Rivets are generally available in the following three head types:

  • Dome Head
  • Coutersunk Head
  • Large Flange Head
Types of Heads

A large flange head provides a larger bearing area, which distributes stresses and increases the stability of the connection. In addition the mandrel locking mechanism of structural blind rivets improves overall shear strength as the mandrel provides additional strength support within the rivet body.

4. Properties of the Connected Material

The strength and hardness of the material being joined has a direct effect on the shear strength of the rivet. If the joining material is soft or brittle, it may break before the rivet reaches its shear strength.

5. Installation Quality

Only correctly installed blind rivets can be maximised. If the rivet is not installed correctly, the desired shear strength may not be achieved.

6. Operating Environment

Extreme high or low temperatures may affect the mechanical properties of a material, thereby reducing its shear strength. For example, some materials may soften or lose strength at high temperatures.

How Much Do Rivets Expand

Expansion is an important indicator of the quality of the connection of a blind rivet. So How Much Do Rivets Expand? Let’s find out together!

Table of Contents

What is the Rivets Expand?

The expansion rate of a blind rivet, also known as the expansion rate or expansion ratio, is the degree to which the tail of the rivet expands and deforms in the hole due to the pull of the mandrel during installation. This parameter expresses the percentage increase in the diameter of the rivet from its initial state after insertion into the hole to when it is fully installed. A satisfactory rate of expansion ensures that the rivet will fill the hole securely and provide a stable mechanical connection.

What is the Rivets Expand?

Expansion Ratio is the ratio of the diameter of the expanded portion of the rivet after installation to its original diameter. It can be expressed as:

Expansion Rate = Diameter After Expansion / Original Diameter

Illustrative Example

Suppose a rivet has an initial diameter of 4.0 mm and after installation it expands to a diameter of 6.0 mm:

Expansion Rate = 6.0mm / 4.0mm = 1.5

The expansion rate of a blind rivet is a key parameter that measures the degree of deformation and expansion of the rivet during installation. The correct rate of expansion provides a strong mechanical connection, prevents loosening, distributes stresses and enhances strength. Therefore, selecting and controlling the proper expansion rate is critical to ensuring the quality and reliability of the connection.

Why is the Expansion Rate of Blind Rivets so Important?

The expansion rate of a blind rivet plays a critical role in the joining process. Correct selection and control of the rivet’s expansion rate ensures that the rivet deforms and expands correctly during installation, thus providing a reliable mechanical connection, preventing loosening and material damage, and improving the quality and durability of the overall connection.

Below are a few areas detailing their primary role:

1. Ensure Tight Fixing

The proper expansion rate allows the rivet to expand sufficiently in the hole to tightly secure the joining material. The expanded rivet completely fills the hole, providing a strong mechanical connection. And it effectively prevents the connection from loosening under vibration or dynamic loading

2. Dispersion of Stresses

Expanded rivets increase the contact area with the hole wall, thereby spreading the stresses applied to the joint. This reduces stress concentration and prevents material rupture or damage.

If you your project materials are softer or more brittle, the proper rate of expansion can effectively disperse the stresses and prevent rupture of these materials due to excessive stress concentrations.

3. Enhanced Shear and Pull-out Strengths

Rivets Sheer Strength

A rivet with a moderate expansion rate provides a larger shear area, which enhances the ability of the joint to resist lateral loads.

The higher the expansion rate, the greater the contact area between the rivet and the hole wall. The pull-out strength of the rivet increases accordingly. The proper expansion ratio can effectively prevent the rivet from coming out under axial load.

4. Adaptation to a Wide Range of Materials

Appropriate expansion ratio enables rivets to adapt to a variety of types of materials, such as metals, plastics, composites, etc., to ensure a good connection on a variety of materials.

5. Reduced Rework and Maintenance

The correct expansion rate ensures that rivets are installed successfully in a single pass. It can help reduce rework and maintenance costs due to connection failure.

Prons and Cons of High Expansion Rate of Blind Rivets

The expansion ratio of blind rivets plays a key role in the connection process, affecting the strength and stability of the connection. Different expansion rates have their advantages and disadvantages, the following are the advantages and disadvantages of high expansion rate and low expansion rate:

Prons

  • Larger contact area: High expansion rate increases the contact area between the rivet and the hole wall, enhancing friction and fixing force.
  • Stress Dispersion: High expansion rates provide better dispersion of stresses and reduce stress concentrations. It can effectively reduce the risk of material rupture or damage, especially for softer or more brittle materials.
  • Higher Tensile and Shear Strength: Expanded rivets provide higher tensile and shear strength. Ideal for applications where higher or dynamic loads need to be applied.
  • Suitable for thinner or softer materials: High expansion rivets form strong joints in thin or soft materials.
Cost of Rivets

Cons

  • Risk of material damage: In harder or thicker materials, excessive expansion rates may result in material damage.
  • Difficulty of installation: Higher installation forces and precision are required to achieve proper expansion. Adds complexity and time to the installation process.

Prons and Cons of Low Expansion Rate of Blind Rivets

Prons

  • For thicker or harder materials: the lower expansion creates sufficient holding power in thicker or harder materials. This ensures that these materials are not damaged by over-expansion.
  • Ease of installation: Lower expansion rates usually require less installation force and less precision. The installation process is easier and faster.

Cons

  • Lower contact area: Lower expansion reduces the contact area between the rivet and the hole wall. May result in loose connections, especially in high vibration or dynamic load environments.
  • Concentration of stress: Rivets with low expansion ratios may not be able to effectively distribute stress.
    Stress is concentrated at the edge of the hole, increasing the risk of material rupture or damage, especially in more brittle materials.
  • Lower Tensile and Shear Strengths: Low expansion rivets provide lower tensile and shear strengths due to the smaller contact area.

How to Choose The Right Expand of Rivets

Ⅰ. Understanding Expansion Rates

Before making a choice on the expansion rate of a rivet, you need to understand what expansion rate is. You can get the answer by contacting us or checking the web.

Ⅱ . Consideration of Material Properties

After understanding the basic definition of expansion rate, you need to have your own judgement on what kind of expansion rate corresponds to different materials.

Softer or more brittle materials (such as plastics or thin metal sheets) usually require a higher expansion rate to increase the contact area to spread the stresses and prevent the material from rupturing.

Ⅲ . Load Requirements

The final point to consider is the load requirement. You need to choose the appropriate rivet expansion rate based on the load the connection needs to withstand. Higher expansion rates usually provide higher pullout and shear forces.

And in vibrating environments, a higher expansion rate helps increase stability.

Conclusion

There isn’t really a universal standard value for rivet expansion. This value will vary depending on the specific application scenario, the characteristics of the joining material and the loads to be carried. However, in general, an expansion rate of between 1.5x and 2x is considered to be an appropriate range for rivets. Expansion rates in this range provide adequate holding power and reliability in most applications.

How Do I Choose The Right Size Pop Rivet? - Select the Length of the Pop Rivets

Blind Rivet Sizes are something that must be considered before purchasing a Blind Rivet. So what are the parts of blind rivet sizes? How do I confirm the size of these parts? And how to measure blind rivets? Through this article, you will understand all of this!

Table of Contents

Why is Blind Rivet Sizes Important?

You need to have a deep understanding of the dimensions of the blind rivets before proceeding with a project. So why is it so important to have a deep understanding of the blind rivet sizes? To put in the first step of starting a project. There are several main reasons:

  1. Correctly sized rivets provide enough tightening force to ensure that the connected parts are held together securely. Under-sizing may result in insufficient tightening force and a loose connection; over-sizing may result in difficult installation or material damage.
  2. The right rivet size and hole match can simplify the installation process, reduce installation time and increase productivity.
  3. Correctly sized rivets are more reliable after installation, reducing the need for rework and maintenance due to connection failure.
  4. In critical structural components, selecting the correct size rivets prevents structural failure and ensures overall structural safety, especially in applications subjected to high loads or critical locations.
  5. matching the rivet diameter to the hole diameter ensures that the rivet expands and deforms correctly in the hole, providing a strong mechanical fixing. If the hole diameter does not match the rivet diameter, the reliability and strength of the connection will be compromised.
Types of Heads

The diameter of a blind rivet is the outside diameter of the rivet stem, which is an important dimension in determining the size of the hole between the rivet and the material being joined. Selecting the proper rivet diameter is critical to ensuring the strength and stability of the connection.

The diagram above illustrates the structure of a blind rivet. The letter “d” represents the diameter of the rivet.

The diameter of a blind rivet is usually expressed in metric (millimeters, mm) or imperial (inches, inch). The following are common specifications:

 Rievt Diameter
MetricInch
2.4mm3/32″
3.2mm1/8″
4.0mm5/32“
4.8mm3/16”
5.0mm6/31″
6.0mm15/64″
6.4mm1/4″

Selecting the proper Blind Rivet diameter is an important step in ensuring a strong and secure connection. Considering factors such as material thickness, hole size, load requirements and material properties can help you determine the most appropriate rivet diameter specification. In practice, following these principles will not only help to achieve a reliable connection, but also avoid installation and use problems associated with poor selection.

How to Choose The Right Rivet Diameter?

When you have this problem, the first thing you need to consider is the load requirements that the connection needs to withstand. Larger diameters provide higher pullout and shear forces.

Of course, if you have holes already drilled in the top of your product, you’ll want to choose a rivet diameter that matches the hole diameter. This will allow the rivet to be inserted and deformed smoothly.

The hole diameter of a blind rivet is the diameter of the hole that needs to be drilled in the material being joined when the rivet is installed. This hole diameter must be slightly larger than the diameter of the rivet itself in order for the rivet to be inserted smoothly and secured properly. Below are some common blind rivet sizes and their corresponding recommended hole diameters:

Rivet Diameter(mm/inchHole Diameter(mm/inch
2.4 mm2.5 – 2.7 mm
3.2 mm3.3 – 3.5 mm
4.0 mm4.1 – 4.3 mm
4.8 mm4.9 – 5.1 mm
5.0 mm5.1 – 5.3 mm
6.0 m6.1 – 6.4 mm
6.4 mm6.5 – 6.8 mm
3/32″ (0.0938 inch)0.098 – 0.102 inch
1/8″ (0.1250 inch)0.129 – 0.133 inch
5/32″ (0.1563 inch)0.161 – 0.165 inch
3/16″ (0.1875 inch)0.192 – 0.196 inch
1/4″ (0.2500 inch)0.255 – 0.261 inch

 

Why is it Important to Match the Rivet Diameter to the Hole Diameter?

Matching rivet diameter to hole diameter is critical to the quality of the riveted joint, affecting the stability, strength and durability of the connection. Both too large and too small hole diameters can have an impact.

Hole Diameter > Rivet Diameter

  1. Rivets do not properly deform and expand to fill the entire hole
  2. The force area of the rivet is reduced and the shear strength decreases
  3. Loose connections may allow moisture and gas to enter the gap between the rivet and the hole wall, resulting in seal failure.
  4. Because the hole is too large, the rivet moves through the hole and can generate unwanted noise, especially in noise-sensitive applications such as mechanical equipment or automotive interiors.

Hole Diameter < Rivet Diameter

  1. Difficult to insert rivets
  2. If the rivet is difficult to insert fully into the hole, the expanding portion of the rivet may not be able to expand and deform sufficiently in the hole, resulting in a failure to form a strong fixing.
  3. When working with brittle materials (e.g., certain plastics, fiberglass), forcing a rivet into a hole that is too small may cause the material to break or crack.

Drill of Blind Rivets

Drilling holes with a drill is the first step in the procedure for installing blind rivets. The size of the drill bit is usually the same as the diameter of the hole. So the degree of match between the drill bit and the rivet diameter can be referred to the degree of match between the rivet diameter and the hole diameter.

Rivet Body Length

The blind rivet Body Length is the total length of the rivet before installation, excluding the head and core section. This length is an important parameter in selecting the right rivet, as it must be long enough to pass through all the layers of material to be joined, while still forming a reliable fixing on the backside of the material.

The body length of the rivet must be long enough to ensure that it will pass through the material to be joined and leave enough to deform and fix. A short body length may result in the rivet not being able to fully penetrate the material to form a reliable connection. The body length of the rivet shall be at least equal to or slightly greater than the cumulative thickness of all layers to be joined.

Assuming that the total thickness of the material to be joined is 5 mm, the body length of the rivet selected should be at least 5 mm to ensure that the rivet can fully penetrate the material and create sufficient holding force on the backside. Typically, a suitable rivet body length may be slightly longer than the total thickness to ensure that there is sufficient room for deformation.

Grip Range

the grip range of blind rivet

The riveting range of a blind rivet, often referred to as the Rivet Grip Range, is the range of thicknesses over which the rivet can effectively grip and hold material. This parameter determines the thickness of the material that the rivet can securely hold during installation and is a key indicator of the type of rivet that is appropriate for the application.

Riveting range refers to the total material thickness that can be reliably clamped by a blind rivet, including the cumulative thickness of all materials clamped. It is usually expressed as a range, e.g. 1.6 – 3.2 mm, indicating that the rivet is suitable for material combinations with thicknesses between 1.6 mm and 3.2 mm.

Correct selection of the riveting range is important.

  • Ensuring Reliable Connections: Selecting the correct rivet range ensures that the rivet creates the proper deformation zone on the backside of the material, providing a reliable mechanical fixing. A rivet with too little or too much reach may result in an unstable connection or failure to install correctly.
  • Accommodate varying material thicknesses: In practical applications, material thicknesses may vary due to manufacturing tolerances, coatings or other factors. Choosing the right rivet range can effectively address these variations and ensure a strong and stable connection.

Examples of common riveting ranges:

  • 1.6 – 3.2 mm: For materials with a total thickness between 1.6 mm and 3.2 mm.
  • 3.2 – 4.8 mm: for materials with a total thickness between 3.2 mm and 4.8 mm.
  • 4.8 – 6.4 mm: for materials with a total thickness between 4.8 mm and 6.4 mm.

Head Diameter and Width

Types of Rivet Heads

Before we go into detail about the diameter and thickness of rivet head types, we need to know that there are several head types of rivets. The main head types of rivets are categorized as follows:

  1. Dome Head
  2. Large Flange Head
  3. Countersunk Head

The “dk” and “k” in the chart above represent the head diameter and head thickness of the blind rivet, respectively.

dk – head diameter

k – head thickness

Dome Head

The Dome Head Blind Rivet is one of the most common head types with a semi-circular head. This design provides good tensile and shear strength.

Head Diameter: typically 1.5 to 2 times the rivet diameter. For example, a 3.2 mm diameter rivet will typically have a head diameter between 6 mm and 6.4 mm.

Head Height: The height of a round head is generally relatively small, providing a moderate level of head projection.

Large Flange Head

Large Flange Head Blind Rivets have a larger head diameter than standard round heads and are often used to increase the contact area and thus spread the pressure. This design is particularly suited to softer materials such as plastics or thin sheet metal.

Head Diameter: Typically 2 to 3 times the diameter of the rivet. For example, a 3.2 mm diameter rivet may have a head diameter between 8 mm and 9.6 mm.

Head Height: The height of a large flange head is generally similar to that of a round head, but its larger head diameter provides a larger support surface.

Countersunk Head

Countersunk head blind rivets have a head designed to be fully embedded in the joining material, with the head being flush with the surface of the material. This design is used where a smooth appearance is desired or to avoid interference from a protruding head.

Head Diameter: Countersunk heads are typically slightly larger than the rivet diameter, depending on the rivet standard. For example, a 3.2 mm diameter rivet will typically have a head diameter between 6.5 mm and 7 mm.

Head Width: The angle of the countersunk head is typically 90 or 120 degrees, depending on the design requirements. The embedment depth and width of the head needs to take into account the thickness of the material being joined.

A proper understanding of the dimensional relationships and standard classifications of blind rivets is the foundation for achieving high-strength, high-consistency connection quality.

Professional advice:

  • When selecting a blind rivet, the clamping range should be the primary reference criterion, rather than the total length. The total length may be misleading under different head types.
  • For environments with vibration or high fatigue, prioritize blind rivets with larger shank diameters and structural designs, and ensure hole diameter fitting accuracy.
  • It is recommended to reserve a ±0.1 mm holding margin in engineering design to account for sheet metal tolerances and installation process variations.

Although blind rivets have a simple structure, their size selection involves multiple factors. When choosing the right blind rivet sizes, it is necessary to comprehensively evaluate factors such as sheet thickness, connection strength requirements, installation process, and hole diameter accuracy.

Step 1: Determine the total thickness of the sheet metal → Match the appropriate rivet grip range

The grip range of a blind rivet refers to the total thickness range of sheet metal that can be reliably clamped after riveting. This is the most critical parameter in selecting the size of a blind rivet.

Example: If the total sheet thickness is 3.0 mm, it is recommended to select specifications with a grip range of 2.5–4.0 mm or 2.0–4.5 mm to ensure adequate clamping and reasonable installation clearance.

  • If the grip is too small, it may result in the rivet core not fully expanding, leading to insufficient clamping force.
  • If the grip is too large, the expansion may be insufficient, causing the rivet core to slip out or the connection to be loose.

✅ It is recommended to prioritize determining the grip range rather than the total length.

Step 2: Confirm material type and connection strength requirements

Different material combinations have different requirements for rivet size and expansion structure:

  • Lightweight structures (such as aluminum + plastic): Choose softer aluminum rivets and control the shaft diameter to prevent material bulging and cracking;
  • Steel + steel structures: Use steel or stainless steel rivets with a shaft diameter of at least 4.0 mm to ensure shear strength;
  • High-strength/high-vibration areas: Prioritize structural rivets and increase the diameter to prevent loosening or fatigue cracks.

Step 3: Select the appropriate shank diameter and head style.

The larger the shank diameter, the greater the load-bearing capacity. Common sizes include:

  • 1/8″ (3.2 mm): Light-duty structures, recommended for single-layer aluminum plates, electronic enclosures, etc.;
  • 5/32″ (4.0 mm): Medium-load connections;
  • 3/16″ (4.8 mm) and above: Heavy-duty structures or multi-layer plate riveting.

Head style selection depends on load requirements and aesthetic needs:

  • Dome Head: General-purpose, suitable for most applications;
  • Countersunk: Suitable for applications requiring a flat surface, such as door panels or panels;
  • Large Flange: Used for soft materials or structures requiring an expanded clamping area, such as plastic or composite panels.

Step 4: Beware of selection pitfalls: Never judge rivet specifications based on “total length”

Many users only refer to the “total length” of rivets when selecting them, while ignoring the most critical “grip range.” This is a common pitfall that leads to riveting failure.

  • Rivets with the same total length may be suitable for completely different grip ranges due to differences in head shape and shaft diameter.
  • The correct approach is: first confirm the structural thickness → match the appropriate grip range → then select the shaft diameter and head shape based on material and process requirements.
Everything You Need to Know About Blind Rivet Sizes

Key factors affecting the selection of blind rivet size

When selecting blind rivet sizes, considering only the thickness of the sheet material is insufficient. The following factors have a decisive influence on selection:

  1. Sheet material type and thickness tolerance: Soft materials (such as plastic or aluminum) require larger rivet head surfaces and clamping allowances. Structures with significant thickness deviations should prioritize rivet specifications with a wide clamping range (Grip).
  2. Load type and strength requirements: If the connection point must withstand high shear or tensile loads, it is recommended to use rivets with larger shank diameters or structural designs, and to match them with appropriate hole diameters and installation forces.
  3. Installation process constraints: Factors such as whether manual assembly or automated equipment is used, and whether there are single-sided accessibility restrictions, will all influence the appropriate configuration of size and head type.
  4. Hole spacing, edge distance, and space constraints: In compact structural areas, consider whether the head type (e.g., countersunk or small cap) interferes with adjacent components, and assess the impact of hole diameter and edge distance on strength.
  5. Rivet material and thermal expansion differences: In structures subject to temperature changes, avoid stress concentration caused by inconsistent material expansion.

grooved rivet

As plastics become more and more popular, rivets are increasingly used in plastics. The use of pop rivets on plastic requires special consideration for optimum performance. You must choose the right type of rivet and material to achieve a long-lasting connection.

Plastic can be softer or more brittle than other materials. Therefore, it is important to choose a blind rivet that will provide a strong connection without damaging the plastic material. To solve this problem, grooved blind rivets are an excellent choice.

Table of Contents

What is a Grooved Blind Rivets?

Grooved pop rivets are a type of blind rivet. Its basic design and working principle is the same as other types of pop rivets.The difference between Grooved pop rivets is that the joints are fixed in a different way.

grooved rivets

Although the installation is the same, grooved blind rivets come with grooves in the rivet body. This groove can be embedded in the connecting plastic during installation to provide additional mechanical grip and retention.

The unique grooved rivet design makes it an excellent choice for joining plastic materials. As long as the size of the rivet you use matches the diameter of the hole, it will create a strong fastening in the plastic.

Strength of Plastics

Strength of Plastic

Plastic, one of the most commonly used materials, is very hard. It is nowhere near as hard as other commonly used materials. The image above demonstrates the strength index of plastic.

Since the strength of plastic is so low and it is used so often, it becomes a problem to connect the plastic components.Grooved pop rivets were created to solve this problem.

Why Use Grooved Blind Rivets to Join Plastics?

The low strength of plastic makes joining it a problem, and Grooved pop rivets offer an excellent solution.Grooved pop rivets offer a number of advantages not found in other blind rivets, making them ideal for joining plastic products. Here are some of the main reasons why grooved pop rivets are great for joining plastic products:

1. Enhanced Grip

Grip of Grooved Pop Rivets

The unique design of the Grooved Blind Rivet features a series of grooves on the surface of the rivet body. These grooves are able to embed themselves in the plastic material during installation, increasing friction and therefore grip. This feature is especially important in softer or more brittle plastics as it prevents the rivet from slipping or loosening under stress.

2. Even Stress Distribution

The groove design helps to spread the stress over a larger area, thus reducing the stress concentration and lowering the risk of material rupture. Plastic materials are relatively fragile and susceptible to damage due to stress concentrations, so grooved blind rivets can better protect the material.

3. Aesthetic Effects

Not only do grooved blind rivets provide a strong mechanical connection, they can also be used to achieve a good integration with the product design by choosing different head styles and colors. Special designs such as large flange heads can provide better decorative effects while increasing the contact area to further enhance the stability of the connection.

4. Efficient Cost Control

Due to the low material cost of grooved blind rivets, simple manufacturing process, and fast installation, the use of them can effectively control production costs, especially in high-volume production. Compared with other fastening methods, the economy and efficiency of grooved blind rivets is more prominent.

How to Choose the Right Grooved Blind Rivets for Plastic?

When choosing the right rivet for riveting plastic materials, you need to find a blind rivet that improves the tight connection without damaging the material.

Here are some things to consider when choosing the right grooved blind rivets for plastic or any soft material:

Geooved Rivets Diameter

When you use grooved pop rivets to join plastic items, the first step should be to determine the diameter of the rivets.

So how do you confirm the diameter of grooved pop rivets? You need to determine the total thickness of the plastic material being joined and the length of the rivets should accommodate the total thickness of the material. The diameter of the rivet needs to match the diameter of the hole. You need to make sure that the connection is stable and that the plastic does not break back.

Grooved Rivets Material

Once the rivet diameter has been determined, you need to consider which material to use for the rivets. The minimum requirement is that the rivet be made of a material that is harder than plastic. Most grooved pop rivets have a body made of aluminum or steel that is a lot harder than plastic. In addition, you need to consider the environment in which it will be used. For example, if you are using it in a marine application, do you need to choose a material that is resistant to corrosion.

Grip Range of Grooved Rivets

Grip range is the thickness of the material to which grooved pop rivets can be riveted.Grip range should match the thickness of the plastic material being joined.

If the grip range is too long, the rivets will be too long to get a neat finish. If the grip range is too short, there is no way to make a good connection. For example, if the total thickness of the plastic is 3.5mm, the grip range of grooved pop rives should be between 3-5mm.

In Addition to Plastic,What are Grooved Rivets Used for?

Grooved pop rivets are good for joining plastic materials in addition to a wide range of other soft or brittle materials. These include the following common materials:

  • lumber
  • Composites
  • Rubber & Elastomers
  • Textiles & Composite Structures
  • Foam
  • Soft metal alloys
Applications Grooved Pop Rivets

Grooved pop rivets are installed in the same steps on these materials as they are on plastic. It is worth noting that when you use grooved pop rivets in your building, make sure they are made of corrosion-resistant materials.

Conclusion

Grooved pop rivets unique groove design works well for joining soft or brittle materials. Plastic materials are no exception. If your project requires joining materials that are not metal or are very thin, grooved pop rivets are an excellent choice.

Whether it’s plastics, composites, wood and fiber materials, grooved pop rivets do a great job of joining!

Why choose peel type blind rivets?If the materials you are joining are soft or brittle, common blind rivets may damage them.Peel type blind rivets are uniquely designed to provide a large contact area and spread the load. Let’s find out more!

Table of Contents

Peel Type Blind Rivets are specially designed blind rivets for joining soft or brittle materials. Its unique structure allows the rivet to form a “Peel” structure during installation, providing a larger contact area and more uniform force distribution for the connected materials. When installing peel rivets, the body of the rivet separates like a banana.

Peel Type Blind Rivets in China

Like other blind rivets, peel blind rivets are structurally different but work on the same principle. Both insert the rivet into a pre-drilled hole, but when the mandrel is pulled, the blind side splits into petals, thus spreading the load on the joint.

Peel type blind rivets are ideal for joining soft and brittle materials. It allows for connections with or higher tensile and shear strengths that will not pull out. In addition to this, it is also possible to join different types of materials. For example fiberglass and wood or metal and plastic.

Types of Peel Type Blind Rivets

In practice, there are several types of peel type blnd rivets depending on the standard. These include dome head peel blind rivets and large flange peel blind rivets.

Dome Head Peel Type Blind Rivets

peel rivets

Dome Head Peel Type Blind Rivets have a round head design for a smooth and decorative appearance. The stripped construction makes this rivet particularly suitable for joining thin plates, brittle materials or applications where uniform stress distribution is required.

Large Flange Head Peel Type Blind Rivets

Why Choose Peel Type Blind Rivets

Compared to Dome Head Peel Type Blind Rivets, large flange head peel rivets provide greater contact area and support. The head has a larger flange, which means the head diameter is larger than the standard rivet head diameter. This design provides a larger surface contact area, which helps to distribute loading stresses and reduce the risk of material damage.

Colored Peel Type Blind Rivets

Peel Rivets Supplier in China - Rivmate Color Rivets

Colored Peel Type Blind Rivets are rivets that are based on the standard Peel Type Blind Rivet and have their head or the entire body of the rivet treated with a special treatment, such as painting or plating, to provide a specific colo. These rivets not only provide a mechanical connection, but also have a decorative or marking function.

This type of peel rivets has a very good decorative effect. The colored coating not only enhances the aesthetic appearance of the rivet, but also matches the surrounding materials or overall design. And of course by using different colors, you can mark specific parts or mounting locations during the assembly process for easy identification and sorting.

Peel type blind rivets are uniquely designed to handle thin panels and brittle materials, providing a strong hold and an attractive appearance, while their corrosion resistance makes them suitable for outdoor applications.

Importance of Using Peel Type Blind Rivets

Peel type blind rivets are widely used in many applications and their importance is reflected in the multiple benefits that come with their unique design and features. The following are the importance of using Peel type blind rivets:

1. Protection of Brittle Materials

peel type blind rivets installing

Peel blind rivets split into multiple “petal” shapes during installation, creating a large back support area. This structure can effectively spread the stress, to avoid the concentrated force caused by the material breakage or cracking, especially for brittle materials such as plastics, fiberglass and composite materials. This characteristic makes Peel Blind Rivets ideal for fixing brittle materials, providing a reliable connection without damaging the material.

2. Suitable for Thin Sheet and Multi-layer Materials

The design of the Peel Blind Rivet allows it to form strong connections in thin plates and multi-layer materials. The peeled petal can provide enough clamping force on the backside to prevent deformation or tearing of the thin material. This is particularly important in areas where thin materials are required, such as electronic equipment, automotive interiors and household appliances.

3. Uniform Stress Distribution

Peel construction provides uniform stress distribution, avoiding the stress concentration problems that can result from traditional rivets or screws. Uniform stress distribution not only improves the strength and stability of the connection, but also extends the service life of the connection part and reduces the risk of fatigue damage.

Types of Peel Type Blind Rivets

4. Anti-vibration Performance

The shape of the peeled petal provides a degree of vibration resistance that helps to absorb and disperse vibration. This makes Peeled Blind Rivets a reliable choice in applications where anti-vibration properties are required, such as automotive and appliance equipment.

5. Versatility and Flexibility

Large Flange Head Peel Pop Rivets

Peel type blind rivets can accommodate a wide range of materials and applications. These include metal, plastic, wood, etc. In addition, Peel Blind Rivets can be coated or color coded as needed to provide additional decoration or functionality.

How Do You Choose the Right Peel Type Blind Rivets?

Like all blind rivets, peel type blind rivets are available in different materials and head styles. To ensure that peel rivets will meet the needs of your project, you need to consider several factors:

  • Material properties
  • Rivet size
  • Head shape
  • Special needs

Material Properties

The most common material combination for peel rivets is aluminum/steel, which meets the strength requirements for the deformation of peel blind rivets while providing a stable and strong connection.

Rivet Size

The dimensions of peel rivets include diameter and length.

You will need to select the appropriate rivet diameter to ensure that it will fit into the pre-drilled hole. The hole diameter is usually 0.1-0.2 mm larger than the rivet diameter to allow for smooth installation.

The next thing to consider is the length. Choose the length of the rivet based on the total thickness of the material to be joined. Generally, the rivet length should be at least 1.5 times longer than the total thickness of the material to ensure adequate stripping and a strong connection.
