Abstract: The invention relates to a method of manufacturing fasteners such as self-piercing rivets, self-piercing studs, plugs, inserts, etc.. In such method a blank is provided and said blank is subjected to a rolling process causing material of the blank to flow radially towards said central axis and axially so as to axially lengthen the blank, with said predetermined geometry of said finished fastener being formed by said rolling process. In addition, a mandrel can be used to precisely define the geometry of the fastener. Fasteners made by the method of the invention are much cheaper than fasteners made by conventional upsetting and extrusion processes. Furthermore, the fasteners made by the method of the invention generally have the advantage of superior grain flow and closer manufacturing tolerances.
