Product Basics & Types
What is a blind rivet?
A blind rivet is a mechanical fastener used to join two or more components when access is available from only one side of the joint. It consists of a rivet body and a mandrel. During installation, the mandrel is pulled through the rivet body, causing the body to deform and form a fastening point on the blind side.
Blind rivets are widely used for sheet metal, enclosures, equipment, and other applications where access to the rear side is limited.

What is the difference between a blind rivet and a pop rivet?
In most industrial applications, blind rivet and pop rivet refer to the same general type of fastener. “Pop rivet” is a commonly used name for a blind rivet, while “blind rivet” is the more general technical term.
Blind rivets are available in different body materials, mandrel materials, head styles, diameters, lengths, and grip ranges. The appropriate specification depends on the joint, material, hole size, and application requirements.
Blind Rivets
What is an open-end blind rivet?
An open-end blind rivet is a common general-purpose blind rivet design. Its rivet body is open at the rear, allowing the mandrel to pass through the body during installation and form the blind-side portion of the joint.
Open-end blind rivets are widely used for general sheet-metal and industrial assembly applications where a standard blind-rivet design is suitable.
Selection should be based on the required diameter, length, grip range, material, head style, and application conditions.
What is a multi-grip blind rivet?
A multi-grip blind rivet is designed to accommodate a wider range of joint thicknesses than a conventional single-grip specification.
This can be useful when material thickness varies between assemblies or when one fastener needs to cover several thickness conditions.
However, the actual grip range must always be checked against the manufacturer's specification. A multi-grip design does not mean that one rivet is suitable for every thickness.

What is a rivet nut?
A rivet nut, also called a threaded insert, is a fastener that creates a reusable internal thread in sheet metal or other thin materials.
It can be installed from one side of the workpiece, making it useful when the rear side of the panel is difficult or impossible to access. Once installed, it provides a threaded point for attaching a screw or bolt.
Rivet nuts are commonly used in enclosures, sheet-metal assemblies, automotive components, equipment, and other applications requiring a threaded connection in thin material.

What is a self-clinching fastener?
A self-clinching fastener is a mechanically installed fastener designed to become permanently secured in a sheet-metal panel.
During installation, the fastener is pressed into a properly prepared hole, allowing part of the panel material to flow into the fastener's locking feature. This creates a secure attachment without requiring a conventional nut on the rear side.
Self-clinching fasteners are commonly used in electrical enclosures, sheet-metal assemblies, electronics, and equipment manufacturing.

What are the different types of blind rivets?
Blind rivets are available in several designs for different joint requirements. Common types include open-end, closed-end, multi-grip, structural, large flange, pull-thru, tri-fold, and peel-type blind rivets.
The main differences are related to rivet body design, deformation behavior, grip capability, head configuration, and application requirements.
When selecting a type, consider the joint materials, total thickness, hole size, access conditions, environmental requirements, and the performance required from the finished joint.
Blind Rivet Types
What is a closed-end blind rivet?
A closed-end blind rivet has a closed rivet body that helps prevent the mandrel from passing completely through the rivet body after setting. This design can be selected when the application requires a more enclosed fastening configuration.
Closed-end blind rivets are commonly considered for applications where containment of the rivet passage is important, including certain equipment and enclosure applications.
Open-End vs Closed-End Blind Rivets
What is a structural blind rivet?
A structural blind rivet is designed for applications with more demanding joint requirements than general-purpose blind rivets.
Structural designs typically use a specialized rivet body and mandrel configuration intended to provide controlled deformation and secure mandrel retention after installation.
The correct structural blind rivet should be selected according to the manufacturer's specifications and the requirements of the joint, including material, thickness, hole size, and application conditions.

What is the grip range of a blind rivet?
The grip range is the range of total material thickness that a particular blind rivet is designed to accommodate.
For example, a rivet specified with a particular grip range is intended for joints whose combined material thickness falls within that range. The grip range is different from the overall length of the rivet.
When selecting a blind rivet, measure the actual joint thickness and compare it with the specified grip range. If the joint thickness falls outside the specified range, the rivet may not form the intended joint.

Blind Rivet Hole Size
What hole size is required for a blind rivet?
The required hole size depends on the blind rivet's nominal diameter and the manufacturer's dimensional specification.
The hole should provide the correct fit for the selected rivet. A hole that is too small can interfere with installation, while an oversized or poorly prepared hole can affect how the rivet forms and fits in the joint.
For production applications, always check the specified hole diameter for the exact rivet series rather than applying one general hole-size rule to all blind rivets.

What is the difference between aluminum and stainless steel blind rivets?
Aluminum and stainless steel blind rivets are used in different application conditions.
Aluminum blind rivets are lightweight and can be suitable when weight and general corrosion considerations are important. Stainless steel blind rivets are often selected when higher corrosion resistance or compatibility with stainless-steel assemblies is required.
The choice should not be based on material alone. Joint materials, environmental exposure, required performance, hole conditions, and the specific rivet design should also be considered.
For a particular application, the appropriate material should be confirmed against the product specification and operating conditions.
Blind Rivets
Can blind rivets be used to join different materials?
Yes. Blind rivets can be used to join components made from different materials, provided that the selected rivet is compatible with the joint and application conditions.
When joining dissimilar materials, consider material compatibility, corrosion risk, joint thickness, hole requirements, and the operating environment.
For example, the combination of the rivet material and the materials being joined can affect corrosion behavior over time. Material selection should therefore be considered together with the complete joint design rather than selecting the rivet based only on its nominal size.
