Aluminum alloy breakstem fasteners with a split tail formation providing a very large blind side bearing area against the rear sheet. The non-structural version of our Klamp-Tite® rivets are ideal for use in thin sheet or low-strength materials.

Klamp-Tite® fasteners are ideal rivets for plastic assembly. Assembly applications include domestic appliances, plastic components, automotive plastic assemblies, and caravans and recreational vehicles.

The Klamp-Tite® rivet is also available as a structural product, containing a visible mechanical lock to give extra strength to the joint.
