Avdelok Lock Bolts

Avdelok is a two piece lock bolt fastener, offering the very best shear and tension performance. Designed for use in very high load applications, Avdelok is commonly used in commercial vehicle, bus and rail construction, as well as heavy duty enclosure construction.

Avdelok is capable of closing gaps between misaligned sheets and has excellent resistance to vibration. Once installed Avdelok is very difficult to remove without special equipment making it ideal for applications where security is a consideration.

For thinner sheet applications a flanged collar can be used to help spread the clamp load. Half collars are available for applications which require a lower profile on the tail side.

Manufactured in Steel, stainless steel and aluminium, Avdelok comes in brazier, truss, countersunk and large flange head forms.
