Abstract
A punch rivet for fastening individual components to one another of which at least one component is formed by a workpiece, with the punch rivet having a flange of larger diameter, a rivet section of smaller diameter and a ring-like component contact surface at the side of the flange adjacent the rivet section and surrounding the rivet section, with the rivet section having at its free end a ring surface for the piercing of the two workpieces which stands at least substantially perpendicular to the central longitudinal axis of the punch rivet and an inner concave ring surface which forms the transition from the end of the punch rivet into the hollow internal space of the rivet section. Ribs extending parallel to the longitudinal axis are provided at the generally cylindrical outer surface of the rivet section and extend up to the free end face of the rivet section.
