How to Choose Blind Nuts for Sheet Metal?

By RIVMATE /January 15,2024 Tite: blind nuts for sheet metal

Importance of Right Blind Nuts for Sheet Metal

For sheet metal, the right blind rivet nut is very important. Blind rivet nuts provide a reliable connection point for sheet metal. Whenever the sheet metal is connected to other components, it gets good feedback, stable and secure. You can solve the problem of connection by means of welding, etc., but it is not as aesthetically pleasing and cost effective as blind nuts.

Blind nuts have been proven in practice to bring a more stable connection and a more cost-effective approach to your sheet metal project. As a result, secure connections will lead to successful projects and more customers.

7 Things to Consider While Choosing Blind Nuts For Sheet Metal

1.Select Material Type

When you are choosing blind nuts for sheet metal, the first thing to consider is what material your sheet metal is made of. Blind nuts are chosen differently for different materials.Here are some common materials for sheet metal:

Steel
Aluminum
Stainless Steel
Other Metal Materials (Copper, Carbon Steel, Nickel Alloys ETC.)

Determining the material of the sheet metal is a very important step. Because the compatibility between metal materials is different, it is very important to choose blind nuts that are compatible with the metal of the sheet material. Only when the materials are compatible with each other can the reliability and durability of the links be ensured. Different metal materials have different mechanical properties and corrosion resistance, so choosing the right blind nuts can prevent problems caused by material mismatches. Problems such as corrosion, galvanic reactions or loose connections are avoided.

2.Calculation of Carrying Capacity

The load capacity of blind nuts is the maximum load or force that blind nuts can withstand. The size of the load carrying capacity depends on the specifications and material of the blind nuts. Factors to be considered are shown below:

Load Requirements: First you need to determine the load requirements of the sheet metal for your project. This can be based on the expected loads, stresses or forces on the project. Determine the range of load carrying capacity required based on the application to the demand.
Selecting the right specification: Select the right specification of blind nuts according to the load requirements of your project. blind nuts’ load carrying capacity parameters can be obtained from the product’s specification sheet or technical data sheet.
System security factor: If your project requires a high level of security, you also need to consider the security factor of the system. (Factor of safety: actual load/blind nut capacity) In order to ensure the reliability and safety of the connection, it is recommended to choose blind nuts with a high factor of safety.

3.Thread Types of Blind Nuts

Threads are the connection points where sheet metal and other components or fittings are bolted together. There are many types of threads, but they are broadly categorized into three thread types: uniform, metric, and special.

Unified Thread: Unified threads are one of the most common types of threads. There are two main types of uniform threads: UNC (coarse thread) and UNF (fine thread).
Metric Thread: Metric threads are internationally recognized thread sizes, such as M series threads, G series threads.
Special threads: Some applications may require special thread types such as tapered, pipe or square threads.

Selecting the appropriate thread type for your specific application maximizes the chance of a good fit between blind nuts and other components.

4.Correct Installation

In general, there are three methods of installing blind nuts: manual installation, motorized installation and pneumatic installation. Different installation methods are suitable for different application scenarios.

Manual Installation: Manual installation is the most basic method of installing blind rivet nuts. It has the advantage of being simple, easy to maneuver, requires no additional power equipment, and is suitable for small-scale installation needs such as home, DIY projects. However, it is slower and may not be practical enough for high-volume or high-efficiency applications.
Motorized Installation: The process of a motorized installation is similar to a manual installation, but uses power tools to provide the power, making the installation faster and more efficient. It has the advantage of being fast and suitable for medium sized installation requirements, which can effectively improve the efficiency of the job and reduce the physical exertion of the operator. However, torque control is required when using power tools to avoid over-tightening or damaging blind rivet nuts.
pneumatic installation: Pneumatic installation typically involves connecting the pneumatic tool to a source of compressed air, which is powered by pneumatic force. The advantages of pneumatic installation are speed and efficiency for large-scale or continuous installation needs. The greater power of the pneumatic tool allows the installation of blind rivet nuts to be accomplished quickly. Pneumatic installation also provides consistent installation effort and torque control.

5.Special Performance

In practice, some application scenarios have special requirements for blind nuts. For example, ultra-high strength, corrosion resistance, heat resistance and so on. So before wholesale blind nuts, you need to have enough knowledge about the application scenario of your project.

Corrosion Resistance
High Temperature Resistance
Electrochemical Compatibility

As sheet metal may be exposed to humidity, acidic, alkaline or other corrosive media, blind rivet nuts should have good corrosion resistance. This can be achieved by selecting suitable materials or applying anti-corrosion coatings such as stainless steel blind rivet nuts or galvanized, nickel-plated, polymer-coated, etc.

6.Quality Certification

You should make sure that your blind nuts are of good quality. For the safety of your project and the satisfaction of your customers, blind nuts should comply with the standards and norms of the industry, and you need to choose a reliable supplier to ensure the quality and certification of the product.

There are several common quality certificates about blind nuts:

ISO 9001

What is a Blind Rivet Used for? Applications of Blind Rivets

2024-01-11
Author: Rivmate Rivet

Blind rivets are a common connecting fastener in the industrial sector and manufacturing. Then what is a blind rivet used for ? They play an important role in joining and reinforcing various material components. Whether it is in automotive manufacturing, aerospace industry, building structures or ship building, blind rivets play an important role.

In this blog, we’ll take an in-depth look at the uses and applications of blind rivets to help you understand why blind rivets are favored in many industries. We will look at how blind rivets work, their advantages and the scenarios in which they are used, and compare them to other fixing methods. Whether you are a professional engineer, manufacturer, or a blind rivet distributor, this article will provide you with valuable information and guidance to help you make informed decisions.

What are Blind Rivets?

The Blind Rivet, also known as the Pop Rivet, is a fastener designed for applications where access to the back of the material is not possible. Pop Rivets are very popular because they can join two or more pieces of material quickly and easily.

A pop rivet consists of two parts: the rivet body and the rivet stem. In the factory production process, the two parts of the blind rivet are produced separately and then assembled for use.

One of the greatest benefits of blind rivets is that there is no way to apply too much or too little pressure to the rivet. If selected properly, the rivet will work best in every installation.

What are Blind Rivets Work?

Blind rivets are a commonly used mechanical joining element that is connected by the breaking of the tail of the rivet body and the expansion of the shell. This type of connection is suitable for situations where operation can only be carried out from one side.

In the process of installing a blind rivet, the tool applies pressure and the tail of the rivet body deforms to form an expanding head, which will form a tight connection with the workpiece, thus firmly fixing the two workpieces together.

What are the Types of Blind Rivets ?

There are many types of blind rivets and they vary in strength and performance. Below I will give you a brief introduction to the various types of blind rivets:

a. Standard Blind Rivet

Standard Blind Rivets have a rounded head, and when the mandrel is pulled, the tail of the rivet body deforms and expands, holding the material together in a stable manner. Standard blind rivets are the most widely used of the blind rivets. It is widely used in automotive, metal, construction, electrical appliances, furniture, containers, air conditioning and other industries.

b. Peel Type Blind Rivet

The peel type blind rivet is a special type of blind rivet that uses the peel principle to make the connection. When the mandrel is dragged over, its tail becomes larger, leaving a tail with four petal shapes. This type of blind rivet is ideal for joining metal to softer materials, and its unique involvement does not damage the surface of the material. peel rivet works well in the construction industry for plasterboard, paint and insulation, and can be used in scenarios such as trailers, plastic parts, upholstery and more.

c. Sealed Type Blind Rivet

Sealed rivets are ideal for use in waterproof applications. These blind rivets have a sealed rivet body with the mandrel head enclosed in the rivet body even after installation.

Sealed rivets effectively prevent liquids and gases from entering or leaving the assembly after installation. They are used in the metal, construction and automotive industries. They may also be found in containers, furniture, air conditioning and heating systems, and electronics.

d. Multi-Grip Blind Rivet

The function of a multi-grip blind rivet is similar to that of a standard blind rivet. multi-grip blind rivets have multiple indentations in the body of the rivet, which widen and provide multiple grips when the mandrel is pulled. This design makes it suitable for joining plastic to plastic and metal to metal.

e. Structural Blind Rivet

Structural Blind Rivets work slightly differently than standard blind rivets. When a structural blind rivet is installed, it locks a portion of the mandrel into the body of the rivet. This creates an extra layer of fastening, which can effectively increase the strength of the rivet joint, as well as enhance the internal strength of the material.

f. Grooved Type Blind Rivet

The grooved Blind Rivet is a blind rivet best suited for softer materials such as plastics and wood. The grooves in this type of blind rivet provide great holding power and are often used to attach metal to building materials such as concrete, brick and wood.
One difference between a grooved blind rivet and a traditional blind rivet is that it does not have to go through the surface of the material. When its mandrel is pulled out, the grooves in the rivet body grip the material by friction.

What is a Blind Rivet Used for?

Blind Rivets are widely used in many fields because of their stable and fast characteristics. They are suitable for applications that require reliable connections and high strength load bearing.So what is blind rivets used for?

Application of Blind Rivets for Automotive Industry

Lockbolt vs Rivet: Comprehensive Comparison and Usage Guide of Lockbolt

2024-01-09
Author: Rivmate Rivet

In the modern manufacturing and assembly industry, Lockbolt and Rivet are two of the most common permanent fasteners. Both can achieve a secure connection, but there are significant differences in structural strength, installation methods, maintenance cycles, and overall costs. This article will conduct a systematic comparison of Lockbolt vs Rivet from the perspective of Rivmate Engineering Fastening Experts.

Lockbolt vs Rivets

Lockbolt rivets and common rivets differ in the way they are joined and the conditions in which they are used; Lockbolt rivets offer greater strength and reliability and are used in situations where high loads are required. The common rivet is a common and widely used connector for general joining needs. The choice of connection depends on the specific application requirements and material properties.

What is a lockbolt ?

Lockbolt is a high-strength, permanent mechanical fastener consisting of a Pin and a Collar. It achieves mechanical interlocking between metals by pressing the locking ring into the groove of the staple using hydraulic or pneumatic tools. This structure offers extremely high shear and tensile strength, and the connection will not loosen or fail due to fatigue. Compared to traditional rivets, Lockbolt is more stable in installation and has a strength approximately 30-40% higher. It is commonly used in high-load scenarios such as railways, aviation, bridges, and heavy machinery.

How do Lockbolt Rivets Work ?

During installation, insert the anchor bolts into the holes, then use a hydraulic tool to press the locking ring into the groove, achieving mechanical locking between the two. The locking ring undergoes plastic deformation under high pressure and bites into the anchor bolt for a secure fixation. After the excess tail is disconnected, a high-strength and permanent connection is formed.

This structure can prevent loosening, and its shear and tensile strength is approximately 30% higher than that of ordinary rivets. Therefore, Lockbolt is often used in high-vibration environments such as railways, aviation, and heavy equipment.

Standard Reference: NAS 1919 / ISO 16120

What is a rivet ?

Rivet is a mechanical fastener that achieves permanent connection by deforming or breaking the core shaft. It is typically composed of a Body and a Mandrel. During installation, the rivet is inserted into a pre-drilled hole, and the core shaft is broken using a rivet gun, causing the dome to expand and lock the workpiece. This connection method does not require threads, and it has the advantages of being lightweight, fast to install, and low in cost.

Rivets are widely used in fields such as automobiles, aviation, home appliances, metal structures and light industry manufacturing. Some structural rivets can withstand high shear and tensile loads.

Standard Reference: ISO 15983 / ASTM F1470

Structural Comparison: Lockbolt vs Rivet

Category	Rivet	Lockbolt
Connection Method	Breaks mandrel or deforms the shank to form a permanent joint	Collar is swaged into grooves on the pin to create a permanent mechanical lock
Operability	Can be installed from one side (blind type)	Requires access to both sides or a through-hole
Strength Performance	Moderate strength, suitable for thin sheet structures	High strength, ideal for heavy-duty structural applications
Vibration Resistance	Good, but may loosen over time under vibration	Excellent, collar lock prevents any loosening
Maintainability	Non-removable	Non-removable (but longer service life)
Common Materials	Aluminum, steel, stainless steel	Alloy steel, stainless steel, titanium
Typical Applications	Automotive, appliances, construction	Railways, aerospace, heavy machinery, bridges

Strength and Durability: Lockbolt vs Rivet Performance Comparison

① Shear and Tensile Strength

From the perspective of structural design, when the lock ring of Lockbolt is combined with the threaded groove, a mechanical lock will be formed on the entire joint surface. This structure can better distribute stress, avoid stress concentration, and enhance the overall connection strength.

The actual measurement data shows that, under the same specification and size, the shear strength of Lockbolt is approximately 25–40% higher than that of ordinary structural rivets. This is why Lockbolt is widely used in high-load environments such as railways, heavy machinery, and bridges.

② Vibration and Fatigue Resistance

Vibration is one of the most common failure causes in metal connections. Traditional rivets tend to experience slight displacement under long-term vibration, which can lead to loosening or cracking of the rivet body. However, Lockbolt achieves high vibration resistance through the permanent interlock between the collar and the groove of the thread. In long-term dynamic load environments, it can effectively prevent micro loosening and the formation of fatigue cracks. This makes Lockbolt the preferred fastener for high-vibration conditions such as railway carriages, engineering machinery chassis, and aviation structures.

③ Corrosion Resistance

The corrosion resistance mainly depends on the material of the fastener. Rivets usually use aluminum, stainless steel or galvanized steel, while Lockbolts typically employ high-strength alloy steel or stainless steel and can enhance the protection level through surface treatments such as galvanizing, nickel coating or Dacromet (a type of electroless nickel coating).

In the ASTM B117, the corrosion resistance lifespan of the coating on Lockbolt can exceed 1000 hours. Therefore, in outdoor, marine or industrial equipment environments with high corrosivity, Lockbolt has a significant advantage.

④ Sealing Capability

In terms of sealing requirements, rivets have a significant advantage. Especially the closed-end rivet, whose tail end is completely sealed, can achieve a waterproof and gas-proof sealing effect. In contrast, Lockbolt focuses more on structural strength and stability rather than anti-seepage performance.

Therefore, in the structural connection application, Lockbolt is recommended; while in waterproof and airtight scenarios (such as aluminum ships and vehicle body shells), Rivet is suggested.

Lockbolt vs Rivet: Applications Comparison

a. Applications of Lockbolt Rivet

High-load applications: Lockbolt rivet is used in applications that require high tensile or shear forces, such as aerospace, railroad, automotive, construction and marine applications.
Requires high strength connections: Because Lockbolt rivet provides high strength connections, it is often used in applications that require reliable and durable connections that can withstand severe service conditions.
Requirement of anti-loosening: The mechanical locking principle of Lockbolt rivet makes it anti-loosening and suitable for vibration and shock environments.

b. Applications of Rivet

General connection needs: Rivet is used in a wide variety of industries including aerospace, automotive manufacturing, construction and electronics. They are primarily used for general joining needs and do not need to be subjected to extremely high loads or harsh working environments.
Quick Installation: Because Rivet is relatively easy to install, the process can be accomplished quickly using a rivet gun or hand riveting tool, making it suitable for scenarios where efficient installation is required.
Affordable: Compared to Lockbolt rivet, Rivet is generally less costly, making it suitable for projects with limited budgets.

Lockbolt vs. Rivet: Comparison of Installation and Maintenance

a. Installation Process Comparison

Rivet Installation Steps:

Pre-drilling
The aperture is usually 0.1–0.2 mm larger than the diameter of the rivet body to ensure the forming space.
Insert Rivet
The rivet body is placed in the hole, and the cap is tightly attached to the surface of the workpiece.
Setting
Use a riveting gun or hydraulic equipment to break the core shaft, thereby forming a locking head at the tail end.
Quality Inspection
Confirm that the cap is flat and the tail is expanded evenly, without any looseness or cracks.

Installation Features:

The operation is simple and can be completed on one side (Blind Access).
The tool is lightweight and suitable for assembly line operations.
Once the rivets are installed, they cannot be removed.

Rivmate Professional Tip:

In applications with high sealing requirements (such as vehicle bodies and ship hulls), the closed-end structural rivet can be selected to enhance water resistance.

Lockbolt Installation Steps:

Insert Pin
The studs pass through the pre-drilled holes and the tail ends protrude from the connection surface.
Apply Collar
The locking ring slides into the bolt slot area, ready for locking.
Swage the Collar
Use specialized hydraulic tools to press the locking ring into the groove to achieve permanent locking.
Pin Tail Break-Off
The tool automatically cuts off the excess tail section, resulting in a neat appearance.

Installation Features:

The installation torque is higher, and a bilateral operation space is required.
It needs to be paired with hydraulic or pneumatic equipment.
After installation, the structural strength is extremely high and the anti-loosening performance is excellent.

Rivmate Professional Tip:

In high-load scenarios such as railway vehicles, heavy machinery, and bridges, the use of Lockbolt can significantly enhance the reliability and lifespan of the connections.

b. Maintenance and Service Life Comparison

Rivet:

Usually no regular maintenance is required.
Under long-term vibration or high stress, slight loosening may occur.
Once damaged, it needs to be drilled out and reinstalled.
The general service life is typically 10–15 years (depending on the environment and material).

Lockbolt:

Almost maintenance-free.
The locking rings are permanently interlocked and there is no risk of loosening.
Suitable for long-term high-load conditions (such as railway bridges, lifting equipment).
The service life can reach more than 25 years, which is longer than that of most riveted structures.

Cost and Efficiency Analysis: Lockbolt vs Rivet

Initial Cost

The single-piece cost of a Rivet is relatively low, and the required tools are simple and lightweight. The price of common aluminum or steel structural rivets is approximately 1/3 to 1/5 of that of a Lockbolt. Therefore, in situations that prioritize cost-effectiveness or require large-scale installation, such as automotive interiors, appliance assembly, and sheet metal connections, rivets are the ideal choice.

Lockbolt：Although its individual price is higher, it possesses greater structural strength and fatigue resistance. In heavy-load structures (such as railway vehicles, wind power equipment, or bridges), its high-strength locking mechanism can significantly extend the service life, thereby reducing the costs of later replacements and downtime.

The test data from Rivmate indicates:

In typical steel structure applications, the initial investment of Lockbolt is approximately 25-40% higher, but it can recover the cost within 3 years by reducing maintenance and downtime.

Life Cycle Cost

Although the rivets are relatively inexpensive initially, they may become loose, corroded or develop fatigue cracks in high-vibration or corrosive environments. Regular inspections and replacements are necessary. This implies that during the product’s lifespan, maintenance and downtime costs may be higher than anticipated.

The Lockbolt structure is robust and requires no maintenance. Under long-term high-stress conditions (such as in railway or bridge connections), the locking ring maintains almost no attenuation of force.

The fatigue test results of Rivmate show that: The Lockbolt maintains 98% of its clamping force after 1 million cycles of load, while the Rivet drops to 82–85%. From a life-cycle perspective, the total cost of ownership (TCO) of the Lockbolt is approximately 20–30% lower than that of the rivet.

FAQ

Q1. Is a lockbolt stronger than a rivet?

Yes, in terms of structural strength and fatigue resistance, Lockbolt typically has 25% – 40% higher strength than Rivet of the same size. This is mainly due to its unique collar swaging structure, which can achieve permanent mechanical interlocking on the thread groove, thereby evenly distributing stress and preventing loosening.

Lockbolt is particularly suitable for structures that can withstand shear loads and vibrations, such as railway vehicles, wind power equipment, lifting machinery, and bridge connections. Although rivets perform well in thin plates and lightweight structures, their clamping force gradually decreases under heavy loads and high vibration conditions. Therefore, Rivet emphasizes light weight and economy, while Lockbolt emphasizes structural strength and stability.

2. Can lockbolts replace welding?

In many cases, Lockbolt can be an ideal alternative to welding. Its connection strength is comparable to that of welded structures, but it is safer to install and has a more stable process. Unlike welding, Lockbolt does not cause a heat affected zone (HAZ) in the metal, thus avoiding material deformation or strength degradation.

Furthermore, the installation of Lockbolt does not require special welding skills and is not affected by humidity, temperature or metal coatings. In high-strength structures (such as railway bridges, steel beam connections or heavy machinery chassis), Lockbolt has been widely used as an alternative to traditional welding.

For areas subjected to impact loads or requiring complete sealing, Lockbolt can be used in conjunction with structural sealant or waterproof sealing solutions to achieve the best results.

3. Are lockbolts reusable?

No.

The Lockbolt is designed as a permanent fastener. During installation, the lock ring undergoes plastic deformation and is pressed into the threaded groove, forming an irreversible mechanical locking structure. To remove it, only specialized cutting tools or grinding methods can be used. Rivmate does not recommend reusing the removed lock bolts because the deformation of the lock ring after removal will affect the accuracy and strength of re-locking. If the structure requires later disassembly and assembly, it is recommended to choose high-strength bolts.

4. Which is more cost-effective for industrial assembly?

From a short-term cost perspective, Rivet is more economical. It has a lower unit price, fast installation speed, and low tool costs, making it suitable for large-scale lightweight assembly line production. However, when analyzed from the total cost of ownership perspective, Lockbolt actually has a greater cost advantage in long-term applications. Due to its maintenance-free feature and high durability, it can significantly reduce the costs of later maintenance and downtime.

In the heavy machinery assembly project, replacing Rivet with Lockbolt can reduce maintenance costs by approximately 35% and extend the structural lifespan by more than 50%.

Build Stronger Connections with Rivmate Lockbolt and Rivet Solutions

In modern industrial assembly and structural engineering, Lockbolt and Rivet each have their own unique value.

In the solar photovoltaic industry, blind rivets for solar industry have become key fasteners for connecting metal frames, borders, and installation components. Unlike general industrial environments, photovoltaic systems are exposed outdoors for long periods, facing multiple challenges such as high temperatures, humidity, wind loads, and long-term vibrations. The requirements for fasteners in the solar industry are far higher than those in general mechanical assemblies. This article will conduct an in-depth analysis from five dimensions: material selection, structural type, corrosion resistance, mechanical strength, and installation efficiency. It aims to help you understand how to choose the appropriate blind rivets for solar industry for different photovoltaic scenarios and provide professional suggestions and application solutions from Rivmate.

Understanding Blind Rivets in Solar Applications

In solar photovoltaic systems, blind rivets for the solar industry play an extremely crucial role in connection. Blind rivets are mechanical fasteners that can be installed from a single side. Their core structure consists of a rivet body and a mandrel. During installation, the mandrel is pulled, causing the tail of the rivet body to undergo plastic deformation, thereby forming a reliable mechanical lock between the workpieces. After the mandrel breaks, it remains inside the rivet body, further enhancing the connection strength and anti-vibration performance.

Blind rivets are widely used in various structural connection scenarios in photovoltaic systems.

Rapid assembly of support structures: Quick fixation between aluminum alloy profiles to ensure the overall stability of the structure.
Fixation of component frames: Used for the combination of aluminum frames and connecting parts to ensure that photovoltaic panels do not shift under long-term wind loads.
Installation of cable trays and windproof clamps: In photovoltaic power stations, blind rivets can achieve lightweight and maintenance-free fastening effects.

Compared with welding and bolted connections, blind rivets have significant advantages:

Single-sided installation: Particularly convenient in narrow or inaccessible structures.
Strong vibration resistance: The mechanical locking after riveting effectively resists stress changes caused by wind loads and thermal expansion and contraction.
Maintenance-free: No need for regular tightening or coating maintenance, suitable for photovoltaic systems with a lifespan of over 25 years.

In addition, blind rivets are not restricted by material types and can be used for connections between various metals such as aluminum, steel, and stainless steel, making them a standardized fastening solution in the manufacturing of photovoltaic racks and modules.

Key Requirements for Choosing Blind Rivets in the Solar Industry

In solar photovoltaic systems, blind rivets are not only fasteners but also an important guarantee for structural reliability. The selection of rivets must simultaneously meet multiple requirements such as durability, strength, weather resistance and installation efficiency. The following are the four key standards for rivets in the photovoltaic industry:

① Superior Corrosion Resistance

The design lifespan of photovoltaic systems is typically over 25 years, and they are exposed to complex environments such as high humidity, acid rain, and salt fog for an extended period. Ordinary aluminum rivets are prone to corrosion under these conditions, leading to loose connections or even failure.

Therefore, it is recommended to use stainless steel rivets (A2/A4 grades) or anodized aluminum rivets, as they can maintain a corrosion-resistant stability of over 1000 hours in the ASTM G85 and ISO 9227 salt spray tests.

This protective performance is particularly crucial for photovoltaic power stations located in coastal areas, deserts or high-salt environments.

② Thermal and UV Resistance

The photovoltaic power station usually operates in a working environment ranging from 70°C to 90°C during summer, and the surface of the components is exposed to intense ultraviolet radiation.

The rivets must have excellent thermal stability and must not loosen due to thermal expansion and contraction. Aluminum alloy and stainless steel rivets perform exceptionally well under thermal cycling conditions, maintaining stable clamping force. At the same time, surface treatment (such as anodization) can prevent ultraviolet aging and extend the service life.

③ Mechanical Strength and Grip Range

The photovoltaic support needs to withstand strong winds, snow loads and long-term vibrations, and has extremely high requirements for the mechanical properties of the fasteners. The rivets should have high shear strength and tensile strength to ensure the stability of the connection point over a long period. It is recommended to use Structural Blind Rivets, whose core shaft locking structure can significantly enhance the vibration resistance and prevent the photovoltaic panel from shifting or the support from losing stability due to loosening.

Furthermore, during the selection process, it is necessary to ensure that the length of the rivets matches the thickness of the material based on the Grip Range.

④ Installation Efficiency and Consistency

The construction of a photovoltaic power station usually involves tens of thousands of connection points. The efficiency of on-site construction directly affects the overall project duration and labor costs.

Using an air riveting gun or cordless electric riveting gun can significantly increase the installation speed and maintain consistent tension output. Compared with traditional manual tools, automated equipment can reduce operational errors and ensure consistent quality at each connection point, which is crucial for large-scale projects.

Best Materials for Blind Rivets in Solar Structures

In solar photovoltaic systems, the selection of the material for the rivets directly affects the lifespan and safety of the structure. As the system is exposed to high temperatures, humidity, sand and salt fog for an extended period, choosing the appropriate material is more crucial than selecting the structural form. The following is an analysis of the performance of several common rivet materials and their recommended applications.

a. Stainless Steel 304 / 316

Stainless steel is the most popular high-end rivet material in the photovoltaic support industry. Its greatest advantage lies in its excellent corrosion resistance and mechanical strength, which ensures stable connection even in environments with salt fog, acid rain and high humidity.

304 stainless steel is suitable for regular outdoor applications;
316 stainless steel contains molybdenum and can resist corrosion from chlorides, making it particularly suitable for coastal areas or photovoltaic power stations in high salt spray environments.

According to the ASTM B117 salt spray testing standard, 316 stainless steel can remain free of corrosion after 1000 hours of testing, making it the preferred choice for long-term outdoor structures.

b. Anodized Aluminum

Anodic oxidation aluminum rivets possess excellent anti-corrosion properties and lightweight advantages. They are lightweight, easy to install, and are particularly suitable for aluminum profile supports and frame components. Additionally, the anodizing process can form an oxide protective layer on the surface, enhancing resistance to ultraviolet rays and corrosion resistance.

These rivets are commonly used in photovoltaic projects that require moderate strength but are sensitive to cost, such as distributed rooftop power stations.

c. Zinc-Plated Steel

Galvanized steel rivets, due to their high strength and economic efficiency, have become a choice for certain low-cost projects. The galvanized coating can provide short-term corrosion protection, but it is prone to oxidation and peeling in high-salt spray or high-humidity environments.

This type of material is more suitable for indoor or non-coastal photovoltaic applications, and is not recommended for use in areas with high humidity, acidic conditions, or heavy dust.

d. Hybrid Rivets

The composite rivets usually adopt a combined design of aluminum rivet body + stainless steel core shaft. It combines the lightweight property of aluminum with the high strength of steel, making it a solution that balances performance and cost. This design effectively prevents the rivet body from corroding and provides sufficient shear strength, making it highly suitable for the assembly of photovoltaic rails, component fixation, and wind-resistant fixture installation.

Industry Standards Reference

To ensure the reliability and consistency of the materials, Rivmate recommends following the following international standards when making the selection:

IEC 61215 – Standard for mechanical load testing of photovoltaic modules, used to assess the impact of fasteners on the overall structure.
ASTM B117 – Standard for salt spray test, used to verify the anti-corrosion performance.

Types of Blind Rivets for Solar Applications

In the solar industry, blind rivets have a variety of applications. A solar panel cannot be stabilized without the use of blind rivets. I will list you some of the commonly used blind rivets in the solar industry.

Blind Rivets for Solar Panel

The installation of solar panels requires the selection of blind rivets of appropriate length, suitable material and weather resistance. The following types of blind rivets are often used for solar panel installation.（Lockbolt Rivet, Bulbtite Rivet, Hemlok Rivet）

Blind Rivets for Solar Tracking Bracket

It takes a lot of strength to hold a solar tracking bracket in place, and many types of blind rivets are needed as well. Commonly used blind rivets are rivet nuts, bulbtite rivets, bom rivets, lockbolt rivet, monobolt rivet, hemlok rivet.

[wpdatatable id=62]

FAQ

Q1: What are the best blind rivets for solar panel installation?

In solar photovoltaic installations, the best choice is structural or closed-end blind rivets. These types of rivets have high shear strength and excellent waterproof sealing properties, and can withstand wind loads, vibrations, and rain erosion.

Rivmate suggests using 316 stainless steel structural blind rivets in the photovoltaic support frames and component frameworks to ensure long-term stability and corrosion resistance.

Q2: Are stainless steel rivets necessary for solar structures?

Yes, it is recommended to use stainless steel rivets, especially in outdoor environments. Photovoltaic systems are usually exposed to high temperatures, humidity and ultraviolet rays, and ordinary aluminum or galvanized rivets are prone to rust.

Type 304 stainless steel is suitable for routine projects, while Type 316 stainless steel, due to its molybdenum content, offers superior corrosion resistance in high salt spray, marine or humid hot environments.

Q3: How to prevent rivet corrosion in solar mounting systems?

To prevent the corrosion of rivets, the key lies in selecting matching materials and providing adequate surface protection. First of all, use rivets that are compatible with the connected materials to avoid electrochemical corrosion (such as the contact between aluminum and steel). Secondly, in high-humidity environments, use anodized aluminum or stainless steel rivets, and add anti-corrosion gaskets (made of EPDM or nylon material). For large-scale photovoltaic power stations, regular salt spray tests and rechecks of the anti-corrosion coating should be conducted to ensure the reliability of the fastening points over the long term.

Q4: Can blind rivets replace bolts in solar supports?

In most photovoltaic installations, blind rivets can partially replace bolt connections, especially for structures with single-sided installation or limited space. Compared to bolts, blind rivets have advantages such as fast installation, resistance to vibration, and maintenance-free. They are highly suitable for fixing photovoltaic supports and frames. However, for areas that require removable or high dynamic loads (such as main structure connections), it is still recommended to retain bolts or use a mixed fastening method.

Author: Rivmate Rivet

Are rivets stronger than bolts ?Not sure how to choose the right fasteners for your project? This blog can solve your problem. I show you the benefits and applications of rivets and bolts. You can quickly solve your confusion with this article.

What is a Rivet ?

Blind rivets, also known as pop rivets, are a kind of rivets suitable for single-sided riveting. Its high reliability, connection strength, long life, easy to operate and use, can be used for aluminum alloy, structural steel and composite materials connection.

Blind Rivet consists of two parts, which are rivet body and nail core. In the production process, the rivet body is usually produced using wire cold heading, plate stamping or tube processing.

Blind rivets are suitable for use where the joint can only be riveted from one side. The rivet is placed into a pre-drilled hole and the core is pulled with a special riveting tool to deform and expand the rivet body to realize the fixing.

What is a Bolt ?

Bolt is a common fastener used to join two or more parts. It usually consists of a rod-like body with external threads, a head, and a nut.

The body of the bolt has external threads for securing the bolt to a part. The head of the bolt typically has a hexagonal shape to allow it to be turned using a wrench or wrench. A nut is a part with internal threads that is used to secure a bolt to another part by threading it to match the bolt’s external threads.

A bolt is used by threading the body of the bolt through the hole of the part to be joined, and then screwing the nut onto the body of the bolt so that the two parts are tightly joined together. By tightening the nut, the bolt creates a pre-pressure that makes the connection stronger and more stable. Bolts can also be disassembled and reused, giving them greater flexibility and convenience.

[wpdatatable id=60]

Rivet vs Bolt Strength Analysis

Shear Strength:
Rivets perform exceptionally well in double-shear structures, with uniform force distribution and effective load dispersion. Particularly, structural rivets, with shear strength reaching 10–12 kN (for a diameter of 6.4mm), are often used in high-vibration areas such as bridges and vehicle frames. In contrast, bolts rely on the frictional force of the threads to transfer shear force, and their structural stability is slightly inferior.
Tensile Strength:
Bolts have a distinct advantage in tensile loads. Their axial preload effectively prevents joint opening, making them suitable for heavy-duty and disassemblable structures. Rivets, lacking the thread preload, are not suitable for high tensile force applications.
Vibration and Fatigue Resistance
Riveted connections without threaded notches have smaller stress concentrations and better fatigue resistance. In contrast, bolts tend to loosen under vibrating conditions and require additional anti-loosening measures (such as thread locking agents or spring washers).
Serviceability & Durability
Rivets are permanent connections and almost maintenance-free. Bolts, on the other hand, can be repeatedly disassembled and assembled, which is convenient for inspection and replacement, but it also means that the connection may weaken due to frequent disassembly and assembly.

Rivet vs Bolt Material Comparison

In the field of engineering fastening, the material and manufacturing process directly determine the strength, durability and applicable environment of fasteners. Rivets and bolts of the same material have significant differences in mechanical properties and corrosion resistance. Therefore, correct material selection is crucial for structural safety.

① Comparison of Material Composition

Rivets are typically made of:
- Aluminum Alloy: Lightweight and corrosion-resistant, suitable for automotive and aviation lightweight structures.
- Carbon / Alloy Steel: High strength, commonly used in bridges and mechanical equipment.
- Stainless Steel 304 / 316: Resistant to salt spray and fatigue, ideal for outdoor or high-humidity environments.
- Monel / Nickel Alloy: Extremely corrosion-resistant, used in marine and aviation structures.
Bolts are often made of:
- High-strength Alloy Steel (Grade 8.8 / 10.9 / 12.9): Possessing excellent tensile strength.
- Carbon Steel: An economical option, widely used in building and mechanical connections.
- Stainless Steel: Suitable for assemblies requiring long-term corrosion resistance.

② Differences in Processing and Connection Principles

Rivet connection achieves permanent fastening by means of “plastic deformation locking”. When cold or hot riveting, the rivet expands in the hole and fills the gap, forming a tight bond. This connection method has no stress concentration points at the threads and has excellent fatigue resistance.
Bolt connection achieves clamping through “pre-tightening force + friction”. The pre-tightening torque provides an initial pressure, but the threads can cause stress concentration and loosening risks. Therefore, in high-vibration environments, anti-loosening washers or thread locking compound are usually required.

③ Rivmate Technical Data

Rivmate test data shows:

The shear strength of the standard 6.4mm structural blind rivet can reach 12.5 kN, which is approximately 80% of the strength of an M8 high-strength bolt.
The weight of an aluminum alloy rivet is only one-third that of a steel bolt of the same size, offering a significant advantage in lightweight assembly.

Industrial Applications: Where Rivets and Bolts Excel

Rivets and bolts play different roles in various industrial fields. The choice of which fastening method to use depends on load characteristics, maintenance requirements and environmental conditions. Research by Rivmate shows that rivets excel in permanent connections and lightweight structures, while bolts have more advantages in maintainable and high-preload structures.

Aerospace

In aircraft manufacturing, rivets play an absolute leading role. The structures used in aviation are mostly made of aluminum alloys and titanium alloys. Welding may cause thermal deformation, while rivets can form high-strength connections at room temperature.

Advantages: Lightweight, high vibration resistance, and long fatigue life.
Representative Applications: Aircraft fuselage skin, wing frame, and cabin panels.

Aerospace rivets (such as those made of Monel and titanium alloys) can maintain stable structural performance throughout a service life of over 25 years.

Automotive Manufacturing

Rivets and bolts are used in parallel in the lightweighting of vehicle bodies and the assembly of electric vehicles.

Rivets Predominant: Suitable for aluminum alloy body, doors, and battery pack structures, facilitating automated installation.
Bolts Predominant: Applied to chassis, suspension, and powertrain systems, facilitating maintenance and replacement.

The Rivmate Structural Blind Rivet has a shear strength of 11kN at the vehicle body connection points and can replace spot welding structures.

Construction & Infrastructure

Large structures such as bridges and steel trusses often use high-strength bolts (Grade 10.9/12.9), which are easy to disassemble for maintenance and inspection.

Rivet Application: In the early days of steel bridges, hot riveting was commonly used. Nowadays, it is only employed in certain structural repairs or decorative connections.
Bolt Application: High pre-tension and friction-type connections ensure structural stability. If maintenance-free and better vibration resistance are pursued, Rivmate Structural Rivet can be considered as an alternative solution.

Rivet vs Bolt: Advantages and Disadvantages

In the field of structural fastening, rivets and bolts each have their own advantages. The choice of which method to use should be determined based on factors such as load type, vibration conditions, maintenance cycle, and structural accessibility. The following is a professional comparison summarized by Rivmate:

Advantages of Rivets

Excellent vibration resistance: The riveted structure forms a tight bond through plastic deformation, unlike bolts which may loosen due to vibration.
Permanent connection: Suitable for structures that cannot or do not need to be disassembled later, such as aircraft skins, bridge nodes, vehicle frames, etc.
Good fatigue resistance: The stress is evenly distributed, especially in the double shear structure, effectively reducing local stress concentration.
Lightweight advantage: The weight of aluminum alloy and stainless steel rivets is only 30%–50% of that of the same specification bolts, which is particularly important in automobiles and aviation.

Disadvantages of Rivets

It cannot be disassembled. If repair is needed, it must be drilled apart.
The installation process is complex and requires special riveting equipment and molds.
Pre-tightening force cannot be applied and it is not suitable for high-tension structures.

Advantages of Bolts

Removable and Reusable: Facilitates maintenance, replacement and regular inspection.
High Tensile Strength: The pre-tightened threads can effectively withstand axial loads, suitable for heavy-duty applications such as bridges, machinery and construction.
Easy Installation: High degree of standardization, universal specifications worldwide, facilitating replacement and on-site operations.

Disadvantages of Bolts

Prone to Loosening: Requires anti-loosening measures (such as locking washers, thread sealants) in a long-term vibrating environment.
Significant Stress Concentration: The root of the thread is a typical fatigue source point, which is prone to cause crack propagation.
Heavier Weight: The overall structure weighs approximately 20% – 30% more than the riveted solution.

FAQ

Q1: Are rivets stronger than bolts in shear?

Yes, in most double-shear structures, rivets typically exhibit superior shear strength compared to bolts. This is because rivets achieve full-contact locking through plastic deformation, enabling uniform stress distribution, whereas bolts primarily rely on friction and localised clamping forces to bear loads. For instance, the Rivmate 6.4mm structural rivet achieves a shear strength of 12.5 kN, equivalent to 80% of an M8 high-strength bolt.

Q2: Can rivets replace bolts in structural applications?

In certain instances, yes. For permanent, vibration-resistant, or difficult-to-maintain structures—such as those in aviation, automotive bodies, or bridge joints—rivets are the superior choice. However, for connections requiring periodic maintenance or disassembly, bolts remain more suitable. Rivmate recommends employing rivets in static loads and high-vibration environments, while utilising bolts in maintainable structures. Combining both achieves optimal performance.

Q3: Why are airplanes riveted instead of bolted?

Aerospace structures demand lightweight construction and fatigue resistance. Rivets are lightweight, require no threaded structures, and do not induce stress concentrations or fatigue crack propagation. Furthermore, rivets form reliable connections between dissimilar materials—such as aluminium alloys and titanium alloys—without thermal influence. Consequently, over 90% of aircraft skins and frames utilise riveting techniques.

Q4: Which is better for vibration — rivet or bolt?

Rivets are demonstrably superior to bolts. Bolts may loosen or experience a reduction in preload under prolonged vibration, whereas the mechanical locking properties of rivets ensure a permanently secure fastening. This is the primary reason rivets are extensively employed in railway rolling stock, automotive chassis, and wind turbine structures.

Q5: Are rivets permanent?

Yes. Once installed, rivets form a permanent, non-removable connection. Should maintenance or replacement be required, disassembly must be achieved through drilling or mechanical cutting. Consequently, Rivmate engineers recommend evaluating future maintenance requirements during the design phase to determine whether to employ riveting or a detachable fastening method.

Discover Rivmate Structural Rivet & Bolt Solutions

In the field of structural fastening, Rivets are not always superior to Bolts. However, they do perform better in terms of shear resistance, vibration resistance and fatigue resistance. In contrast, bolts still have the advantage in scenarios that require high tensile loads, ease of maintenance and repeatable assembly. Therefore, the best solution needs to be reasonably selected and combined based on working conditions, load forms and usage cycles.

These types of stainless steel rivet nuts can be used for everyday industrial needs and projects. Of course, Rivmate also offers a customized rivet nut service for your project.

Stainless Steel Hex Rivet Nuts

Hexagonal rivet nut is one of the more commonly used rivet nuts, head type has a countersunk head hexagonal rivet nut, round head hexagonal rivet nut, flat head hexagonal rivet nut, small countersunk head hexagonal rivet nut and so on.

Hexagonal rivet nut mounting holes are hexagonal holes, hexagonal rivet nut hexagonal design can effectively prevent the installation of the nut rotation, to strengthen the riveting effect of rivet nuts. Mainly used in non-structural bearing bolt connection, such as railroad buses, ships and other interior parts of the connection, the advantages of its light weight, without the fixed pallet nut, the back of the substrate without operating space can still be used.

Stainless Steel Round Rivet Nuts

Round rivet nuts are a special type of rivet nut, also known as round embedded nuts or circular embedded nuts. They have a cylindrical shape and internal threads.

Round rivet nuts are primarily used in applications where a hole needs to be formed in the surface of the material. They can be used on a variety of materials such as metal, plastic, wood, and more. During installation, round rivet nuts are embedded in the material to form a hole that can be threaded for bolts or screws.

One of the advantages of round rivet nuts is that they can be used on rough surfaces or where special installation requirements are needed. Due to their cylindrical design, round rivet nuts provide greater contact area and stability during installation. This makes them suitable for connections that need to withstand high tensile forces or torque.

Stainless Steel Countersunk Rivet Nuts

The Countersunk Rivet Nut has a surface that is flush with the top of the nut and is typically used in applications that require a bolt or screw to be embedded in the surface.

The unique design of the Countersunk rivet nut allows it to be aligned with the material surface after installation, reducing the amount of bumps on the material surface. This provides a smoother appearance, reduces drag and prevents thread exposure.

Stainless Steel Thread Rivet Nuts

Threaded Rivet Nut is internally threaded and is typically used where it is necessary to form a threaded connection inside the material that can be bolted or screwed. It creates a strong threaded connection point inside the material for mounting and securing other parts.

How to Measure Blind Rivets?

2023-12-27
Author: Rivmate Rivet

Blind rivets are a very convenient and fast fastener for connectors. In order to ensure that blind rivets are connected accurately, it is important to measure their dimensions and parameters correctly. Do you know how to measure blind rivets? This article will provide you with a comprehensive guide that will teach you how to measure blind rivets accurately. Ensure that your project has the most secure connections possible.

Preparation Before Measuring Blind Rivets

Before measuring blind rivets, you need to prepare the following tools and materials:

Calipers: for measuring the length and diameter of the blind rivets.
Thread gauge: for measuring the type of threads of the blind rivet.
Mold or Measuring Tool: Used to measure the shape of the head of the blind rivet.

How to Measure Blind Rivets?

Blind Rivets are generally categorized into three head types – Dome Head, CSK Head, and Large Flange Head. There are some differences in measurements between different head sizes.

Dome Head and Large Flange Head

d : Diameter

L : body length

dk : rivet head dimeter

k : rivet head thickness

dm : mandrel diameter

p : mandrel reveal

CSK Head (Countersunk Head)

d : Diameter

L : body length

dk : rivet head dimeter

k : rivet head thickness

dm : mandrel diameter

p : mandrel reveal

After understanding the parameters of blind rivets, let’s learn more about how to measure blind rivets.

How are the Diameters of a Rivet Measured? （d）

The diameter of the blind rivet is an important parameter that affects the strength of the connection and the selection of the right size. It plays an important role in the strength and robustness of the connection, the effectiveness of the core extraction, material suitability and installation requirements.

When measuring the diameter of a blind rivet, the topmost part of the rivet should be measured, not the mandrel or head width.
The diameter of the blind rivet should be measured several times and averaged. This will help to calculate the correct size of the blind rivet.
Please note that the diameter of blind rivets is usually measured in millimeters (mm).

How to Measure Rivet Length ? (L)

Selection of the appropriate blind rivet length ensures the range of connections, penetration capability, core pulling effect and safety of the installation, resulting in a high quality connection. The length of the Blind Rivet varies depending on the use and requirements.

When measuring the length, you need to keep the surface of the blind rivet clean and perpendicular to the measuring tool. You need to select the appropriate Blind Rivet length. A blind rivet that is too long may fail to install or cause damage to the material being installed or to objects behind the hole.

How to Measure Rivet Head Diameter ?

The rivet head of a blind rivet provides support and retention, transfer of load, reinforcement of the connection, and cosmetic protection during the joining process. Choosing the right rivet head ensures a quality, reliable and durable connection.

There are three general head shapes for blind rivets: countersunk head, round head and large flange head. In most cases, round head blind rivets will fulfill the requirements of the application. Large flange head blind rivets are used where greater support and load carrying capacity is required. And countersunk head blind rivets are suitable for applications that require a flat, bump-free joint surface. When selecting a head type, it is important to consider the requirements of the connection, the nature of the material, and the desired support and appearance.

Differences in Blind Rivet Threads

Blind Rivets have different threads depending on the application. The internal threads of a blind rivet are usually located at the bottom of the rivet. It can accept threaded bolts or nuts for a stronger connection. Internally threaded blind rivets are typically used in applications that require a removable connection.

The external threads are usually located on the top of the rivet. Capable of accepting nuts or other threaded connectors for a stronger connection. Externally threaded blind rivets are typically used in applications where additional holding force is required during the joining process or where they need to be used in conjunction with other threaded connectors.

Grip Range of Blind Rivets

The grip range of a blind rivet is the range of thicknesses of plates or connections it can join. It indicates the distance between the minimum and maximum thickness of the material that a blind rivet can grip.
The grip range is an important parameter. If the grip range of a blind rivet exceeds the thickness range of the material to be joined, the connection may fail or not achieve the required strength and reliability.

Typically, the length of the blind rivet and the core length (the length of the blind rivet sticking out of the sheet) affects the range of its grip range.
When selecting a blind rivet, it is necessary to determine the appropriate grip range of the blind rivet based on the thickness of the material to be joined.

How do I Know My Rivet Size ?

Blind Rivets are typically sized by diameter, length and core length. When approaching the blind rivet business, you will often see numbers such as 1/8″, 1/4″, etc., which represent the diameter of the blind rivet. Take a 1/8″ (0.125 inch) blind rivet as an example to explain how to determine the size of a blind rivet:

Diameter: The diameter of a blind rivet is usually expressed in inches or millimeters. 1/8″ blind rivets, indicates a diameter of 1/8″ or 3.175 mm.

The conversion of inches to millimeters can be done very simply by following the formula. (mm = in/0.039370)

A complete description of a rivet requires knowing its rivet body length in addition to its diameter. A 3.0 x 6.0 is used as an example for illustration.3.0 means the diameter of the blind rivet is 3.0mm, or 7/61″ inch. 6.0 means Body Length is 6.0-7.0mm length.

With the above information, you will have a complete representation of the size of the rivets.

Rivet Hole Size Chart

To achieve a tight joint, in addition to the rivet size selection being important, the rivet hole is also critical. After determining the rivet size, the hole size must be marked for drilling. Generally, the diameter of the rivet needs to be slightly smaller than the diameter of the hole. This allows the rivet to be inserted without any obstacles, maximizing the gap filling and achieving a tight connection.

[wpdatatable id=58]

FAQs

How to Measure Rivet Length?

The length of the rivet refers to the total length from the bottom of the rivet head to the tail end of the rivet body, excluding the part of the core shaft pull rod. When selecting the type, it should be calculated based on the total thickness of the two layers of materials (Grip Thickness):

Recommended formula: Length of rivet ≈ Total thickness of material + 1.5 × Diameter of rivet. Ensure that the length of the rivet is sufficient to achieve expansion locking, but do not make it too long to avoid affecting the appearance.

What Is Grip Range?

Grip Range refers to the range of material thickness that the rivets can firmly grip. It is usually indicated in the product specifications (for example: 3.0–5.0 mm). If the thickness of the connecting material exceeds this range, the rivets cannot fully expand and lock securely; conversely, if the thickness is too thin, the rivets will be pulled out and the connection will be unstable.

Rivmate suggests: The material thickness should be as close as possible to the middle value within the Grip Range to achieve the best riveting strength.

What Hole Size Should I Drill?

The aperture should be slightly larger than the diameter of the rivet body to allow insertion without any obvious gap. Generally, it is recommended that the aperture size be equal to the rivet diameter plus 0.1–0.2 mm. For example: 4.8 mm rivet → The recommended aperture size is 4.9–5.0 mm.

Which Head Style Should I Use?

Blind rivets can be selected with different head types depending on their application:

Dome Head: The most versatile option, suitable for metal plate connections.
Countersunk Head: Suitable for smooth surfaces, such as car exteriors.
Large Flange: Used for soft materials or in situations where pressure dispersion is required.

The choice of hairstyle not only affects appearance, but also relates to the distribution of force and the tensile strength.

How to Ensure Accurate Measurement?

Before measurement, please ensure:

Use a vernier caliper or digital caliper to measure the diameter and length;
Remove burrs at the edge of the holes to prevent dimensional errors;
Check the flatness of the rivet head to ensure consistent measurement points.

In mass production, the Rivet Gauge provided by Rivmate can be used for quick inspection to ensure consistency and assembly efficiency.

Choose Rivmate Blind Rivet Solutions

Accurate measurement of Blind Rivets is not only the first step in selection, but also a crucial step to ensure the structural stability and product reliability. By precisely determining the diameter, length, grip range, and hole diameter, you can significantly improve the assembly accuracy and avoid problems such as loosening, cracking, or insufficient strength.

How do Rivet Nuts Work ?

In order to solve the shortcomings of thin metal plate, thin tube welding nut easy to melt, tapping the internal thread easy to slip, BF Goodrich invented the rivet nut in 1930.

Because of their practicality, rivet nuts are now widely used in a variety of sheet metal connections, including automotive, machine building, and aerospace. So do you know how do rivet nuts work?

Below I will cover several aspects of how rivet nuts work and why they provide a strong connection.

What is a Rivet Nut?

A rivet nut is a special type of threaded fastener. It is a device that acts to form a threaded hole and provide a threaded connection in a thin plate, pipe or other thin material.

The rivet nut is similar in appearance to a nut, but the rivet nut is threaded on the inside. It has a flat bottom and an open top with grooves and indentations on the bottom that increase the resistance to rotation forces with the material.

Rivet nut can be made in different fabrication materials such as steel, aluminum, stainless steel, copper, carbon steel, etc. depending on your project needs. They come in a variety of different sizes and thread specifications, which you can customize from the rivet nut manufacturer according to your specific needs.

How do Rivet Nuts Work ?

The essence of the rivet nut is to make a tight connection by expansion. It is not possible to use bolts or screws when making fastening connections in thin plates. Therefore, a rivet nut is required to provide a connection point for bolts or screws.

The rivet nut is threaded by applying pressure to deform the rivet nut horizontally.The youtube video below shows you in detail how do rivet nuts work.

The rivet nut application consists of the following components: the rivet nut, the rivet nut tool, the substrate on which the rivet nut is to be installed, the bolt or screw. The rivet nut connects the parts by tightly joining the bolts together through the mechanics of the threads inside it. The rivet nut is pulled using a screw on a rivet gun, which compresses the rivet nut longitudinally and creates a raised deformation at the top, thus clamping the riveted joint.

What are the Benefits of Rivet Nuts?

Rivet nuts provide a fast, reliable and cost-effective solution for connecting sheet metal parts to each other. Rivet nuts have many advantages over nuts and bolts.

Seven Advantages of Rivet Nuts：

Strong and reliable threaded connections provide a durable and dependable anchor point for bolts or other threaded fasteners.
Ability to distribute the load over a large surface area. Prevents material deformation or damage compared to conventional nuts.
Rivet nuts can be assembled significantly faster than methods such as welding or crimping. It can effectively reduce production time and cost.
Rivet nuts create a flat, low-extension appearance on the surface of the material. Improves the overall aesthetics of the finished product.

How to Choose the Right Rivet Nut for Your Project?

Do you want to understand in more detail how do rivet nuts work? Box back to How do rivet nuts provide a secure connection for your project? Below I will explain in detail how each step of the rivet nut works in six areas.

Choose Right Rivet Nuts

How to choose the right rivet nut for your project?You need to consider many perspectives, such as the required application and material, the appropriate type of rivet nut and specifications.

Material Type: The first thing to consider before wholesaling rivet nuts is which type of rivet nut to use. Different materials of rivet nuts are used in different scenarios. Such as aluminum, stainless steel, carbon steel, copper, plastic, composite materials and so on. You need to make sure that the rivet nut and the material to be riveted are compatible so that there is a stable threaded connection.

Suitable Outer Diameter and Length: Before wholesaling rivet nuts, you need to have a clear idea of the diameter and length of the rivet nuts you need. Make sure that the specification of the rivet nut matches the size of the hole. The rivet nut should not be much larger or smaller than the diameter of the hole if it is to function correctly, ensuring that the threaded portion should be fully embedded in the material.

Rivet nut manufacturers also confirm product information based on this.

Rivet Nut Types: There are many types of rivet nuts to solve a variety of different application scenarios. From the material point of view, including stainless steel rivet nuts, carbon steel rivet nuts, aluminum rivet nuts, copper rivet nuts and so on. In terms of appearance, there are hex rivet nut, round rivet nut, open end rivet nut, closed end rivet nut, countersunk rivet nut and so on.

Provide Suitable Holes for Rivet Nuts

In order to ensure the tightness of the rivet nut connection, in general, the holes in the plate should be 1mm more than the outer diameter of the rivet nut. that is to say, when the outer diameter of the rivet nut is 4.7mm, the open hole should be 4.8mm. according to a large number of practice has shown that the tightness of this is the best.

The following table shows the relationship between the outside diameter of the rivet nut and the corresponding hole.

[wpdatatable id=57]

Correct Insertion of The Rivet Nut

Insert the rivet nut into the drilled hole, you need to make sure that the head of the rivet nut is flush with the surface of the material. The riveting is then accomplished by means of a riveting tool so that the threaded portion of the rivet nut is fully seated in the hole.

Installation of Rivet Nuts

There are many tools for installing rivet nuts, but they are broadly categorized into three types: hand rivet nut tools, electric rivet nut tools and pneumatic rivet nut tools.

Installation of rivet nuts can be accomplished regardless of the installation tool used. Installing rivet nuts is a simple process that can be accomplished in a few easy steps.

Screw the rivet nut onto the mandrel of the tool.
Place the rivet nut into the pre-drilled hole. Start the tool and pull the rivet nut.
The rivet nut is deformed and tightly attached to the material.
Reverse the tool out of the center of the rivet nut

Where to Buy Rivet Nuts

There are many ways to buy rivet nuts. These include buying in small quantities, buying in bulk and customizing rivet nuts. If you are looking to purchase rivet nuts in small quantities, it is fastest and most convenient to purchase them directly from your local hardware store. If you are looking to buy rivet nuts in bulk or customized rivet nuts for your project, then you can seek the help of a rivet nut manufacturer.
