ABSTRACT:
A blind fastener is disclosed comprised of a rivet having an axial internally threaded bore and a threaded pin to be received within the threaded bore of the rivet. The rivet has a head at one end thereof, and preferably a chamfered bore at the other end thereof. The rivet is provided with a plurality of cuts in the outer wall of the rivet, extending axially along the wall of the rivet and forming zones of weakness in the rivet wall. The threaded pin has an outwardly protruding portion, preferably bell-shaped, and a head at the other end of the pin, such as a square head, for threading the pin through the rivet. When the pin is threaded into the rivet, the protruding bell-shaped end portion thereof is received within the chamfered bore of the rivet. The rivet-pin assembly is positioned in a hole of parts to be fastened. Further turning of the pin causes radial expansion of the inner end of the rivet against the zones of weakness therein, formed by the cuts in the rivet wall, and forms a blind head for locking the fastener in position on the parts which are fastened. The rivet is preferably formed of a rubber-like elastomeric material, and the pin is comprised of a metal.
