Rivnut® by Bollhoff is the global leader in rivetnut technology. Rivnuts® were invented in the mid 30's as a way to attach material to the outside of an aircraft wing. There was no chance to access the inside of the wing to attach a nut, so the Rivnut was able to install threads inside the wing from the outside surface. This is known as a blind application, access to only one side of the assembly while fastening. Bollhoff, a leading German firm aquired the Rivnut business and added to an already impressive line of products similar to Rivnuts, called Rivkle (pronounced riv'-clay").

Rinvuts are available from 6-32 or M3 to 1/2-13 or M12. Materials available include Steel, Aluminum, 400 Series Stainless, Non Magnetic Stainless. Platings are available in Zinc, RohS Compliant Zinc, Cadmium and Zinc/Tin.
