Abstract
The invention proposes a blind fastening element, which is constructed similarly to a screw. The fastening element thus has a head (), which is disposed on one end of the shaft () and has a contact surface, which faces toward the shaft, for contact on the object to be fastened. On the opposite front end, the fastening element has a punch face (), which runs approximately transversely to the longitudinal axis and is enclosed by a closed punch edge (). The diameter of said punch face is less than the diameter of the shaft, for example, the diameter is in the range of approximately 70% to 30% of the diameter of the shaft. The shaft itself may be smooth on its exterior, if the fastening element is to be used as a blind rivet, or may have a thread (), however, if the fastening element is to be fastened after the punch procedure by rotating.
