摘要
The rivet nut, consisting of a head (2) and a hollow shank with crimping and internally threaded (5) zones, has the latter pre-threaded to receive a self-braking insert (10) which has a number of cylindrical spirals and at least one polygonal self-braking spiral (12). The polygonal spiral is situated after the extreme position of a broach used to crimp the nut before it receives a bolt. The body of the nut can be of steel, stainless steel, aluminium or copper, and the insert (10) can be made from stainless steel, bronze or aluminium, with its surface treated with a dry lubricant or a coating of silver, cadmium, copper or zinc.
