Avbolt

An Avbolt is a blind bolt that clamps two or more parts through a drilled hole. It gives a high strength fixing from one side of the work. It often comes as a two piece or three piece system.

An Avbolt suits structural and general engineering where access is from one side only. It takes a nut and often a washer of the same thread and class. It is set with a spanner or a socket.

Avbolts are often made in steel. Steel gives high strength for structural applications. They may have a protective coating.

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

Ask for a mill test certificate for the steel. Check the bolt for correct dimensions and thread. On receipt, inspect for damage and confirm the system type.
