ABSTRACT:
A fastener with a shank and, arranged at one end of the shank, a head intended for welding to a workpiece, has multiple detent pawls formed on the shank that extend radially outward from the shank toward the head and that are elastically resilient in the radially inward direction. On the outside, each detent pawl has an engagement recess with support surfaces. The shank has a longitudinal hole, in which is located a stud, wherein one end of the stud projects out of the longitudinal hole and forms the head for welding. Also formed on the shank is a flange that is elastically resilient in the axial direction, whose outermost edge region is located opposite the engagement recess of the detent pawls.
