A variable grip blind rivet has a rivet body with a first shank adapted to be inserted into a hole in a workpiece and having an axial bore, and a flange at a first end of the first shank for abutting the workpiece when the first shank is inserted into the hole in the workpiece. A mandrel has a head, for engaging a second end of the first shank, and a second shank adapted to extend through the axial bore. The head has an abutment portion for abutting the first end of the first shank. 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.

Variable grip blind rivet

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.

A method of loading a column of hollow rivets on to a mandrel for use in blind-riveting. The rivets are provided assembled head-to-tail on a strand made of resilient plastics material. The strand may be tubular or have at least a hollow end portion and be connected to the mandrel by being pushed on to a reduced end portion of the mandrel so that the strand grips the mandrel and the rivets are slid off the strand and on to the mandrel.

Method of loading rivets

A stacking device for stacking headed tubular fasteners. The device comprises air blowing means which accelerates an end fastener in a guide relative to the remaining fasteners in the guide thereby ensuring that each fastener leaves the guide separately without jamming to fall into a stacking passage in which the fasteners form a column one-above-the-other. The stacking device is utilized for stacking rivets in a rivet packaging machine which assembles a column of rivets on a sleeve made of resilient plastics material for later transfer to the mandrel of a pull-through blind riveting tool.
