Open-end blind rivets are among the most commonly used fasteners for applications where only one side of the workpiece is accessible. Their simplicity, strength, and versatility make them indispensable across construction, automotive, electronics, and aerospace manufacturing. As a reliable fastening solution for metal, plastic, and composite assemblies, open-end rivets provide consistent performance in both high-volume production and field installation.
Understanding Open-End Blind Rivets
Open-end rivets consist of a hollow rivet body paired with a mandrel. During installation, the mandrel is pulled through the rivet body, causing the tail to expand and form a secondary head on the blind side of the material. The mandrel breaks off at a predetermined point, leaving a clean, secure, vibration-resistant joint. This simple yet effective design allows strong fastening using only front-side access.

Advantages of Open-End Rivets
One-Sided Installation
Perfect for blind applications where the rear of the assembly cannot be reached.
Simple, Fast Installation
Requires only a standard blind rivet setting tool, making it ideal for production lines or field repairs.
Wide Material and Size Range
Available in multiple diameters, grip ranges, and materials to fit diverse requirements.
Durable Joint Performance
Provides strong, vibration-resistant fastening capable of withstanding demanding environments.
Installation Process
Prepare the Materials
Drill or punch a hole through the components to be joined, matching the rivet diameter.
Insert the Rivet
Place the rivet in the hole with the flange seated flush against the surface.
Set the Rivet
Use a blind rivet gun to pull the mandrel, expanding the body on the blind side and locking the materials together.
Complete the Joint
The mandrel snaps at the break point, leaving a clean, secure installation.
