ABSTRACT:
The invention relates to a rotationally symmetrical fastening element with an axially centralized rounded tip for a friction-welded joint with a flat component. The tip is adjoined by a conical lateral surface, the conical lateral surface transitioning into a flute for receiving a material melted during friction-welding, and by a shoulder, wherein the shoulder surrounds the flute, is axially recessed in relation to the tip and transitions into the friction-welded joint.
