Avdelok

An Avdelok is a two part fastener that forms a high strength joint in sheet and structural assemblies. It has a pin and a collar that lock together when set.

An Avdelok fastener clamps metal panels and structures where a high strength joint is needed. It is set from one side with a placing tool, so access to the back is not required. The pin and collar work as a pair, and the collar is swaged onto the pin to lock the joint.

Avdelok fasteners are often made in steel, stainless steel or aluminium. Steel gives high strength, stainless steel resists corrosion, and aluminium keeps weight down.

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. Check the pin and collar fit, the head shape and that the grooves are clean on receipt.
