Countersunk Stainless Steel Rivet With Steel Mandrel

A blind fastener with a self-contained carbon steel mandrel which permits the formation of an upset on the blind end of the rivet and expansion of the rivet shank during rivet setting. The steel mandrel is pulled into or against the rivet body, breaking at or near the junction of the mandrel shank and its upset end. The head of the rivet body is countersunk at an angle of 120°.
