The fasteners join similar or dissimilar metals and thicknesses reportedly forming an almost air and watertight joint with good vibration resistance and minimal distortion to the substrates. The self-piercing fasteners eliminate spot welding and riveting operations. To install the Fas-ners a machine uses a punch-and-die operation that feeds, punches, inserts, and locks fasteners into a solid joint in a single high-cycle operation. The machines range from single-hit units to completely automated turnkey systems.
