Abstract
A variable grip blind rivet includes a tubular rivet body and a mandrel. The rivet body has a first shank, insertable into a hole in a workpiece, and a flange at a first end of the first shank for abutting the workpiece when so inserted. The mandrel has a head, for engaging a second end of the first shank, and a second shank adapted to extend through the axial bore of the rivet body. The head has an abutment portion for abutting the first end of the first shank, and the second shank has a first reduced diameter portion adapted to break when a predetermined tensile is loaded applied. At least one protrusion adjacent the abutment portion defines a recess for receiving the first end of the first shank during setting of the rivet.
