ABSTRACT:
A blind setting rivet which may be used to secure two layers of materials together is disclosed which drills and deburrs its own aperture through the two layers of materials and attaches the materials together in a secure, water-resistant, sealed manner. The rivet includes deburring ears to remove any burrs from the drilling operation, thus ensuring that the rivet head will fit in a flat manner on the outside surface of the materials to be secured. The shaft used to set the rivet has a plurality of spiral flutes located around the circumference thereof, which spiral flutes ensure the application of a uniform amount of force to set the rivet prior to fracture of the shaft.
