Pair a lockbolt with a collar to form an assembly that withstands vibration and heavy loads without loosening to permanently fasten joints. Insert the lockbolt, also known as a bolt pin, into a predrilled hole like a rivet. Then use a lockbolt riveter (sold separately) to push the collar onto the shaft of the bolt and lock it into place. The bolt shaft is cut to set flush with the collar upon installation.
As part of a lockbolt-and-collar assembly, the lockbolt joins the materials to be fastened.
