About the Rivnut®


Rivnut®, the original, blind-installed, internally threaded rivet, was invented (patent #2,149,199) in 1936 for the purpose of attaching a rubber aircraft wing deicer extrusion to the leading edge of the wing. The Rivnut® riveted the aluminum wing skin to the inner aluminum spar and then accepted a mating screw to attach the rubber deicer.


The Rivnut® fastener was given a military specification of MS27130 and an aerospace standard of NAS1329 and NAS1330. Use of the Rivnut® expanded within the military and aerospace markets, and soon became popular in general industry because of its many design and assembly advantages.
