Abstract
A method of manufacturing self-pierce rivets from a length of wire comprises separating the length of wire to form a plurality of slugs, each slug defining a head end and a tail end. The method further comprises forging a plurality of rivets from the slugs, each rivet having a head formed from the head end of a slug and a tip formed from the tail end of that slug, the head and the tip of the rivet being separated by a shank which defines a longitudinal axis, the rivet having a bore which runs substantially longitudinally through the tip and at least part way along the shank. For each of the plurality of rivets, the method comprises performing a machining operation on the tip the rivet or on the tail end of the slug from which the rivet was forged.
