Types of Blind Rivets

Rivet is one of the very widely used fasteners. So do you know how do rivets work?This guide will give you detailed information about how rivets work and how they connect.

Table of Contents

What Are Rivets?

Rivets are a very common fastener for thin plate connections. You can find rivets anywhere, whether it’s in cars, airplanes, bridges, furniture, appliances or industrial equipment.

Types of pop rivets - Rivmate Blind Rivet Supplier

So how is a rivet constructed? The basic construction of a rivet consists of three parts: 1. rivet head 2. rivet stem 3. rivet tail.

  • Head: fixed to the surface of the material, used to provide clamping force. Common types include round head, large brim, countersunk head, etc.
  • Shank: The long column part of the rivet, which undergoes plastic deformation during installation.
  • Tail: The material that deforms after stretching or compression and clamps the joint together with the head.

How do Rivets Work? - Core Elements

Why do rivets form a tight connection? Then you need to have a clear perception of how rivets work. Here are the key factors that influence “how do rivets work”.

1. Plastic Deformation

Plastic deformation of the rivet tail is the key to the connection:

  • Deformation to absorb external forces: the tail deforms to absorb the applied tensile force or pressure.
  • Material fixation: the diameter of the deformed tail is larger than the hole diameter, preventing the rivet from coming out.

2. Clamping Force

Peel Type Blind Rivets for Soft Materials

What is the clamping force of a rivet? It is when the head and tail of the rivet together exert a clamping force on the material. Its function is mainly to prevent the material from slipping or loosening and to maintain the stability of the connection.

Of course, you can avoid material damage by spreading the stress through head design (e.g., large flange head blind rivets).

3.Material Compatibility

The properties of the rivet and the connecting material need to be matched:

  • Ensure that the strength of the rivet is sufficient to support the connection requirements.
  • Prevent failure due to galvanic corrosion.

How do Rivets Work?

So do you know how to install rivets?How do rivets work?Rivets are installed to achieve a stable mechanical connection through the following steps.

1. Pre-drill Holes and Insert Rivets

Drilling or Punching:

  • Drill holes in the material to be joined to match the rivet diameter (usually 0.1-0.2mm larger than the rivet diameter).
How to Install Pop Rivets ? - Drill and Check

Insert the rivet:

  • Insert the rivet into the hole in the material with the head against the surface of the material.

2. Riveting tool action

The use of a rivet gun to apply tension or pressure to the stem or mandrel of a rivet. The rivet gun causes the end of the rivet to deform plastically, creating a strong “locking” structure.

3. Material Clamping

The rivet gun causes the tail of the rivet to deform so that the tail and head work together to securely attach the rivet to the material being joined.

  • The head provides the clamping force on the outside and the deformed tail locks the material on the inside.
  • The materials are tightly clamped to each other to form a strong connection.

How Different Types of Rivets Work?

Although rivets work on roughly the same principle, there are some differences in how different types of rivets work.

Solid Rivets

Principle of operation:

  • Use hammering, hydraulic or pneumatic equipment to deform the end of the rivet to form a lock.
  • Commonly used in bridges, airplanes, and high-strength steel structures.

Deformation characteristics:

  • Plastic deformation of the entire rivet stem.

Blind Rivets

Principle of operation:

  • The tool applies tensile force to pull the mandrel upward, the shell tail deforms to clamp the material, and the mandrel breaks to complete the installation. Suitable for one-sided operation, commonly used for thin steel plates, tubes or closed structures.

Deformation Features:

  • Deformation of shell tail, broken mandrel provides additional locking force.

Structural Rivets

Principle of operation:

  • Based on a blind rivet, a mechanical lock is formed between the mandrel and the shell, providing increased strength and vibration resistance.
  • Commonly used in high vibration, high dynamic load environments (e.g. aerospace, railroad vehicles).
Interlock Structural Rivets

Deformation characteristics:

  • Mandrel locking for enhanced resistance to loosening.

Principle of operation:

  • When the tool applies pressure, the tail of the rivet splits into multiple directions, creating a large deformation.
  • Suitable for soft materials or thin plates to prevent material damage.
Tri Fold Blind Rivets for Soft Materials

Deformation characteristics:

  • Tail splits outward to increase clamping area.

Aside from understanding how do rivets work, you also need to use the pros and cons of using rivets.

Advantages of Using Rivets

  • Reliable mechanical connection: rivets form a fixing by plastic deformation, providing high tensile and shear strength, suitable for scenarios subjected to static or dynamic loads.
  • No Thermal Effects: Riveting is a cold working process and does not have the thermal effects on material properties that welding does.
  • Suitable for one-sided operation: the use of blind rivets can be accomplished in areas where the back side is inaccessible, such as closed structures, tubes or frames.
  • Easy to operate: riveting equipment is simple and easy to operate, suitable for assembly line assembly and field construction.
  • Applicable to a variety of materials: rivets are suitable for metal (such as steel, stainless steel, aluminum) as well as non-metallic materials (such as plastics, composite materials), stable connection performance.
  • Lightweight design: lightweight materials such as aluminum rivets can be used in applications that require weight reduction.
  • No need for special environment: riveting does not require a dry, wind-free operating environment like welding, and can be installed in wet or harsh conditions.
  • Low cost and high efficiency riveting process is simple and fast, especially suitable for high-volume production, reducing production and assembly costs.
What Are Pop Rivets Used For? - Pop Rivets for Electronic Devices

Disadvantages of Using Rivets

  • Limited strength: riveted joints are usually less strong than welded or bolted joints. 
  • Unsuitable for thick materials: rivets are limited in length, making it difficult to join thicker materials or multiple layers of materials.
  • Holes weaken the material: riveting requires drilling holes in the material, which may weaken the overall strength of the material, especially in thin plates or stress critical areas.
  • The operation process is not reversible: it is difficult to recover the rivet once it has been deformed.

What is Riveting Steel?

Riveting Steel refers to the joining or fixing of Steel using the Riveting technique. Riveting is a process of firmly joining two or more pieces of steel together through the mechanical deformation of the rivet, and is a common method of mechanical joining, especially suitable for thin plates, frames, pipes and other scenarios.

Why do Airplanes Use Rivets Instead of Welds?

Simple and flexible compared to welding and bolting, Riveting Steel is an efficient and reliable method of joining steel and is particularly suited to thin steel plates, closed structures and scenarios where one-sided operation is required.

Why Use Blind Rivets to Riveting Steel?

Steel is the most used type of metal material in practical applications. So how to go about fixing steel materials or steel products has become a matter of concern. Blind Rivets provide a solution for steel that is superior in terms of efficiency, strength and practicality. Below are the main reasons and advantages of using blind rivets for steel project joining:

Riveting Effect of Stainless Steel Blind Rivets

1. High Strength Connections

Blind rivets can provide fastened connections from low to high strength. Whereas steel is often used in products or applications that require high strength, steel blind rivets can provide high tensile and shear strength through rivet tail deformation.

Special structural rivets such as monobolt rivets can further enhance the strength of the connection and are ideal for heavy steel structures.

2.Avoiding Thermal Effects

Conventional welded connections can result in localized heat affected zone (HAZ) distortion or loss of strength of the steel, which is completely avoided with blind rivets.

Blind rivets use mechanical deformation to complete the connection and do not generate high temperatures during installation. In applications where material properties are required to be maintained, such as high tensile steel or thin steel plates, blind rivets are a safer choice.

3. Suitable for Dynamic Loads and Vibration Environments

One great feature of the blind rivet is that it has a tough joint that absorbs some of the vibration and shock.

In high vibration applications such as machinery and vehicles, blind rivets are more resistant to breakaway than bolts. And monobolt rivets and interlock rivets ensure that the joint remains stable under dynamic loads.

4. Provision of Special Functions

There are many types of blind rivets that can provide special features for steel projects. For example, sealed rivets are used to provide a sealed connection to steel to prevent liquid or gas leakage. Use heat resistant rivets to join steel that requires heat resistance, such as boiler casings or high temperature equipment.

What Rivets to Use on Steel?

Blind Rivet Mandrel

Steel material is basically less likely to react chemically with other metal materials, so basically all common metal blind rivets can come riveting steel.

We can choose the best blind rivet for your steel project based on your project needs.

  • High strength, common connection: use steel blind rivets. it can provide high connection strength and good compatibility with steel for most industrial and construction applications.
  • Light duty connections or thin steel plates: use aluminium mandrel steel body blind rivets. it provides a good lightweight design and puts less pressure on thin steel plates to avoid deformation of the material.
  • High vibration environments or high load requirements: use monobolt rivets. structural rivets provide maximum strength and excellent relaxation properties, making them ideal for high intensity and dynamic load environments.
  • Sealing requirements: use watertight blind rivets. Waterproof rivets can provide waterproof and dustproof effect, suitable for pipe connection or outdoor assembly.

How to Install Q Rivets

Installing a blind rivet on steel is no different than installing a regular blind rivet. Both use a riveting tool to complete the rivet installation process.

The important thing to note is that you need to make sure that the holes are accurate and in place when you do this. This will ensure the stability of riveting steel.

The process of forming a tight connection with a blind rivet is divided into four parts: use rivet gun > deformation of the rivet tail > mandrel breakage > removal of the broken core.

Why Use Pop Rivets to Riveting Aluminum?

In practice, using pop rivets to riveting aluminum is a very common connection. Why use pop rivets to riveting aluminum?

The main reason is that the properties of pop rivets are perfectly matched to those of aluminum. Here are some of the main reasons.

1. Aluminum material characteristics adapted to the performance of the Pop Rivet

Before we understand the reason for this, we need to briefly understand the following characteristics of aluminum materials. Aluminum materials usually have the following characteristics:

  • Aluminum is lightweight and moderately strong, but more easily deformed than steel.
  • Aluminum’s ductility and plasticity is better, but the thin plate is susceptible to local stress damage.
  • Aluminum is highly resistant to corrosion and is suitable for outdoor and wet environments.
Automatic Riveting Stainless Steel Products

So how do pop rivets rivet aluminum?

  • Blind Rivets create a clamping force through deformation and can securely join aluminum without damaging its surface or structure.
  • Blind rivets with large brims distribute stresses to protect the thin-walled or soft characteristics of aluminum.

2.Lightweighting Needs

Aluminum is known to be a very lightweight metal material. Aluminum products are widely used in scenarios where weight reduction is required (e.g., aerospace, automotive, construction, etc.).

And POP Rivets are also well adapted to light weight. Aluminum POP Rivets are also very lightweight, keeping the overall lightness of the connection area. The use of aluminum rivets avoids the need for additional weight and provides relatively good joint strength.

3. Provides a reliable mechanical connection

Aluminum materials have some points that require extra attention when making connections.

  • Aluminum has a low hardness and welding may cause thermal damage or distortion.
  • For thin plates and tubes, direct tapping is not suitable.
Riveting Stainless Steel

Compared to other fasteners, the advantages of POP Rivets are well demonstrated when rivet aluminum.

  • POP Rivets form a strong mechanical joint by pulling the end of the mandrel during riveting and deforming it to fit tightly into the aluminum material.
  • After installation, the connection point has good rivet tensile strength and rivet shear strength, which is suitable for most aluminum application scenarios.

4. Corrosion Resistance

Aluminum materials generally possess good corrosion resistance. The aluminum oxide layer on the surface of aluminum is naturally resistant to corrosion. However, galvanic corrosion may be accelerated if improper fasteners (e.g. carbon steel screws) are used.

Aluminum POP Rivets, on the other hand, have the same electrochemical properties as aluminum and can avoid galvanic corrosion. If the use of the environment is more demanding, you can also choose stainless steel blind rivets or zinc-plated steel mandrel blister rivets, used in conjunction with aluminum.

What Rivets to Use on Aluminum?

There are many factors to consider when selecting pop rivets for riveting aluminum. This includes the need to ensure that the performance, material and design characteristics of the rivets can be matched to the properties of the aluminum to achieve the best possible joint and ensure long-term stability.

Material Compatibility

When choosing rivets for rivet aluminum, the first thing to consider is the compatibility between different metal materials. Rivet material should be compatible with aluminum to avoid galvanic corrosion and mechanical damage.

  • Aluminum blind rivets: recommended for aluminum rivets, with the same electrochemical properties as the aluminum substrate to reduce the risk of corrosion.
  • Stainless steel rivets: for high strength or highly corrosive environments, but be aware that contact with aluminum may initiate galvanic corrosion.
  • Galvanized steel rivets: for medium strength requirements, lower cost, need surface treatment to reduce corrosion.

Recommendation: In high humidity or salt spray environments, prefer aluminum rivets or anodized stainless steel rivets.

Rivet Head Types

Types of Aluminum Blid Rivets Head

In addition to the material of the rivet, it is necessary to select the appropriate head design based on the thickness, application and appearance requirements of the aluminum.

  • Dome Head Blind Rivets: This is a general purpose head design suitable for most aluminum joining scenarios. It provides adequate clamping force and an attractive appearance after installation.
  • Large Flange Head Blind Rivets: Suitable for thin-walled aluminum or softer aluminum alloys, disperses stress and protects the aluminum surface. For example, doors, windows, decorative parts and other parts susceptible to tension.
  • Countersunk Head Blind Rivets: Used for applications that require a flat surface, such as decorative panels, aviation components. Ensure that there are no protruding points on the surface after riveting.

Special Features Applied

Certain application scenarios may require rivets with special features:

  • Sealed Rivets (Sealed Rivets): for waterproof, dustproof aluminum structural joints.
  • Multi-Grip Rivets (Multi-Grip Rivets): to adapt to different thicknesses of aluminum, reducing the variety of rivet specifications.

FAQs

Will Aluminum Rivets Melt?

Aluminum rivets will not melt below 1220°F (660°C) and are very stable under common temperature conditions. However, under extreme heat conditions (e.g., fire, welding flames), aluminum rivets may melt or soften. If the application involves high temperatures, it is recommended that rivets be made of heat-resistant materials or be insulated for protection.

Will Aluminum Rivets Corrode?

Aluminum rivets have good corrosion resistance in conventional environments, but may corrode in special environments. For example, contact with other metals, environmental humidity and chemical contamination. The risk of corrosion of aluminum rivets can be greatly reduced by proper material selection, use of isolation measures and regular maintenance to ensure their stable performance in a variety of environments.

Can I Use Stainless Rivets on Aluminum?

The use of stainless steel rivets on aluminum is possible, but special attention needs to be paid to galvanic corrosion. This is because stainless steel rivets in contact with aluminum may lead to galvanic corrosion of the aluminum. So we need to take some measures to avoid this situation. It is recommended to add insulating shims or coatings to isolate the dissimilar metals in contact.

How do Avex Rivets Work?

Like other blind rivets, avex rivets form a tight connection by the expansion and deformation of the rivet body. Once you have done all the pre-riveting preparation, the riveting process is as simple as mounting the avex rivets on the workpiece and pressing the tool button.

Below are the basic installation steps for avex rivets.

1. Preparation Stage

The installation of Avex rivets requires pre-drilling of holes, which is the basis of all riveting operations.

  • Drilling: Drill holes of suitable diameter in the material to be joined.
    The hole diameter is slightly larger than the rivet diameter (e.g. a 4.8mm diameter rivet requires a 5.0mm hole).
  • Rivet Selection: Select an Avex rivet that is suitable for the range of material thicknesses.
    For example, one Avex rivet may cover a total material thickness of 2.0mm-6.0mm.

2. Inserting the Rivet

 Insert the rivet body of the Avex rivet into the pre-drilled hole, making sure that the head of the rivet (usually rounded, large brimmed, or countersunk) fits snugly against the surface of the workpiece.

3. Installation Tool Preparation

How to Choose Right Door Rivets for Door

The installation of blind rivets usually requires the use of a rivet gun (manual, electric or pneumatic rivet tool).

For riveting of rivets, the operator needs to use the rivet gun to clamp the rivet mandrel. The pulling jaws of the rivet gun grasp the end of the mandrel, ready to apply tension.

4. Pulling Mandrel

The rivet body undergoes a series of changes when pressure is applied to the rivet. The following is the process of change.

  1. Pulling effect: The rivet gun applies upward pulling force by pulling the mandrel, so that the tail of the rivet begins to expand and deform.
  2. Rivet body deformation: The tail of the rivet body is pushed outward by the head of the mandrel to form a wide riveting surface.
  3. Multi-Grip Function: The deformation of the rivet body tail is designed to accommodate materials of varying thicknesses, ensuring that gaps between materials are completely filled.

5. Mandrel Breakage

What is the Rivets Expand?

When the tensile force on the mandrel reaches a set value (usually determined by the design of the mandrel’s break point), the mandrel breaks at a predetermined location, creating a flush riveted joint.

The riveted joint is completed:

  • The end of the rivet body firmly clamps the connecting material, providing a secure hold.
  • The residual portion of the mandrel does not affect the function of the rivet and the break point is smooth and aesthetically pleasing.

5 Advantages of Avex Rivets(Multi Grip Blind Rivets)

Here are some of the most important benefits of avex rivets.

Tips for Choosing the Right Avex Rivets

The trick to choosing the right avex rivets is that you need to be very knowledgeable about your business needs. You need multi grip blind rivets that can fully meet the needs of your application.

Determine the Range of Material Thicknesses

Before choosing avex rivets, business owners need to account for the total thickness range of the joining material, including the stacked thickness of all layers.

  • Avex Rivets are multi-grip rivets where a single model can accommodate multiple thickness ranges. Simply select the rivet size that covers that thickness range.
the grip range of blind rivet

Example:For a total thickness of 3mm-5mm, select Avex Rivets labeled for 2mm-6mm.

Note: Avoid rivets with a grip range much greater than the actual thickness to ensure clamping force and deflection.

Selecting the Right Head Type

  • Dome Head: This is the generic type that applies to the vast majority of connection scenarios. This provides a moderate contact area and good clamping force.
  • Large Flange Head: Suitable for thin plates, soft or brittle materials (e.g. plastics, composites). The cap rim distributes the pressure and prevents the material from being damaged.
  • Countersunk Head: For applications where a flat surface or hidden rivet head is required. Examples include decorative structures or aerodynamically demanding scenarios.

Selecting the Right Diameter Specification

Select the rivet diameter according to the hole diameter and load requirements of the connected material.

  • Hole Diameter Requirement: The rivet diameter should match the hole diameter, usually the hole diameter is 0.1-0.2mm larger than the rivet diameter.
  • Load Requirements: The larger the diameter, the greater the clamping force and shear resistance provided by the rivet.

Example:

  • For lightweight components (e.g., electronic equipment panels), use 3.2mm or 4.0mm rivets.
  • For components that carry higher loads, such as automotive frames, use 4.8mm or larger diameter rivets.

Q Rivets Installation

Why does rivet have a tail? Do you know what the purpose of a rivet tail is? By reading this post, you will learn everything you need to know about rivet tails. This includes the types of rivet tails as well as the reasons and types of rivet tails that exist. Let’s explore this together!

Table of Contents

What is the Tail of a Rivet? (Rivet Tail)

Blind Rivet is composed of two parts: 1. Rivet body (rivet tail) 2. Rivet mandrel.  Rivet tail is an important part of the Blind Rivet.Rivet tail is the part of the rivet formed after the deformation of the rivet in the assembly process, its main role is to fix the riveted parts and provide the mechanical strength of the connection.

Peel Type Blind Rivets for Soft Materials

Blind Rivets are the key part of the riveting process where the rivet tail and rivet head are pressed against each other to secure the materials to be joined. The rivet tail is the key element in the riveting process. It is deformed by expansion or compression to create a stable fastening effect.

Why Does Rivet Have a Tail?

From the above information, I think you already know that rivets are made up of a rivet tail and a rivet mandrel. So why do rivets need to have rivet tails in their design and how does the Rivet tail play a role in the riveting process?The Rivet tail is the key to the rivet’s ability to make a strong connection.Its presence allows the rivet to provide long-lasting mechanical support during the assembly process, spread the load, and ensure vibration resistance and durability of the connection.The Rivet tail is the key to the rivet’s ability to achieve a strong connection. Here’s why and what it does:

1. Provide a Strong Mechanical Connection

Rivets form a locking structure through the deformation of their tails. This structure ensures that the rivet cannot be loosened from the hole, thus holding the joined workpieces firmly together.

  • The Rivet Tail presses against the back of the workpiece to create a clamping force for permanent riveting.
  • The strength of the joint is supported by the head and tail of the rivet, with additional support provided by the deformation of the tail.

2. Distribute the Load and Protect the Connecting Material

The deformation of the Rivet tail will increase the contact area between the rivet and the workpiece, thus effectively dispersing the concentrated load and avoiding excessive local stresses.

  • The ‘cap edge’ or ‘flap’ formed at the end of the rivet tail can reduce the shear or compressive stress on the connected material.
  • Particularly suitable for joining thin or soft materials to prevent tearing or damage to the material.

3. Ensure Vibration Resistance of the Connection

The deformation of the Rivet tail will tightly adhere to the surface of the workpiece, which effectively prevents the rivet from loosening or falling out under high vibration or dynamic loads.

  • The Rivet tail provides additional tightening force to prevent the connection from loosening due to prolonged use or vibration.
  • In high vibration environments (e.g. automotive, aerospace equipment), the deformed tail structure enhances the durability of the connection.

4. Improved Shear and Tensile Resistance

Unlike screws, the deformed structure of the Rivet tail allows the rivet to withstand higher shear and tensile forces.

  • The rivet tail, by plastic deformation close to the workpiece, can withstand external shear forces, thus enhancing the overall strength of the joint.
  • It resists pull-out forces and ensures that the workpiece will not come loose under external forces.

5. Simplifies the Installation Process

Deformation of the Rivet tail allows the rivet to form a tight connection. There is no need to use nuts or washers at all, which greatly simplifies the installation process.

  • The connection is made by simple pulling of the rivet and is suitable for one-sided operation.
  • This improves installation efficiency, especially in confined spaces or mass production.

The Process of Rivet tail Formation

What is the Rivets Expand?

The process of forming the Rivet tail represents the process of forming a complete fastening of the rivet. Below is the process of rivet tail formation.

  1. Insertion of the rivet: The tail of the rivet is first inserted into the hole of the workpiece to be joined, with the head of the rivet flat against the side of the workpiece.
  2. Applying Tension: A rivet gun is used to stretch the core of the rivet, causing the tail to expand and compress the workpiece.
  3. Tail deformation fixation: The tail of the rivet deforms plastically after the application of force to form a mushroom, cone or other shaped structure that is firmly attached to the workpiece.

Types of Rivet Tails

There are several different types of rivet tails when forming a stable connection with a blind rivet.

  • Mushroom Tail: A round cap-like structure formed by the expansion of the rivet tail. The rivet tail is formed into a round tail when a standard blind rivet is installed. This type of rivet tail provides a larger contact area and distributes pressure.
  • Flared Tail: The tail of the rivet expands outward to form a petal-like structure, commonly found in Peel type blind rivets and tri fold rivets.Blind rivets that can form a flared tail are ideal for joining thinner or softer materials, as this structure prevents the material from being damaged by stress.
  • Locking Tail: In structural blind rivets, the tail is locked to the rivet core to form a high strength connection. This type of rivet tail provides a fixing that is resistant to vibration and high tensile forces.

Tips of Choosing the Types of Rivet Tails

Which specific rivet tails are right for your project? There are really three main things to consider:

  1. Material compatibility: rivet tail deformation requires sufficient toughness, the material should be adapted to the hardness of the connected workpiece to avoid inadequate deformation or damage to the workpiece.
  2. Tail size and shape: the final shape of the rivet tail determines the firmness of its connection and anti-shear performance, need to choose the appropriate tail type according to the application scenario.
  3. Installation Tools and Methods: Different rivet types require matching tools to form the tail. For example, standard blind rivets and structural rivets use different types of rivet guns.
