Abstract
A fastener nut for hydroformed parts comprises a nut body for receiving a threaded fastener and a locking ring with depending fingers that is received on the nut body. The nut body is adapted to pierce and then form a collar thereabout in a hydroformed part while the part remains in a die cavity under hydroforming pressure. The nut body and the collar formed thereby have a configuration that prevents turning of the locking ring while permitting turning of the nut body relative to the locking ring on full insertion of the nut in the collar, and a cam surface on the nut body that on partial turning of the nut body then forces the locking ring into locking engagement with the collar to thereby attach the fastener nut to the hydroformed part.
