Abstract: A blind rivet includes a tubular shell formed with an enlarged head and a shank, and a mandrel formed with a stem and an enlarged head. The shell and mandrel are insertable from one side of a plurality of members to be fastened together through aligned openings such that a pull force applied to the mandrel from that side causes the shell shank to bulge outwardly, and thereby to securely fasten the members between the shell head and the bulged portion of the shell shank. The mandrel includes two gripping portions axially spaced from the mandrel head and each other by bridging portions of smaller diameter than the gripping portions such that the shank is firmly gripped by the outer surfaces of the two gripping portions when the mandrel is pulled to outwardly bulge the shell shank.
