Interlock Rivet

An interlock rivet is a blind rivet with a locking feature that holds the mandrel in place after setting. It provides a vibration resistant joint and a dome head finish.

An interlock rivet sets into a drilled hole and locks the mandrel in place for a vibration resistant joint. It often suits panels and frames that see movement. A rivet gun or hand tool sets it from one side.

Interlock rivets are often made in aluminium, which is light and resists corrosion. Aluminium is softer than steel, so consider the load requirements.

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

Request a certificate of conformance and verify the rivet diameter and grip range on delivery. For critical joints, ask for a mill test certificate for the aluminium.
