Avex Rivet

A blind rivet is a permanent fastener set from one side of a joint. It pulls a mandrel through the body to form a tail, clamping the parts together.

An Avex rivet joins sheets and panels where only one side can be reached. It sets with a rivet tool that pulls the mandrel, and the mandrel often stays locked in the body after setting. A dome head spreads the clamp load over the top sheet.

This kind of rivet is often made in aluminium, which keeps weight low and resists corrosion in indoor and sheltered outdoor use. The mandrel can be steel or aluminium depending on the joint strength needed.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance with the batch. On receipt, check the rivet body for cracks, the mandrel for straightness, and that the head sits flat against a test plate.
