ABSTRACT:
A hollow rivet and a setting mandrel are injection molded of thermoplastic material to form a single piece blind rivet or a blind rivet type foot of a fastener for moldings and the like. A draw shank and an enlarged head of the setting mandrel are interconnected by a break joint, and another break joint connects the mandrel with the surrounding tubular shank of the hollow rivet. Setting pull on the draw shank first ruptures the break joint between the mandrel and the hollow rivet, then sets the rivet, and finally ruptures the break joint between the draw shank and the mandrel head.
