Abstract
A method for the attachment of the fastener element to a workpiece with the aid of a washer and also a die button are described. The fastener element has a flange of larger diameter, a rivet section of smaller diameter which extends away from the flange and a workpiece contact surface at the side of the flange adjacent the rivet section. The die button is provided to receive a washer and has a central post the end face of which lies at least substantially flush with the side of the washer adjacent to the workpiece. The non-pre-pierced workpiece is pierced by the said end face of the central post and the free end of the rivet section and the rivet section of the fastener element is subsequently deformed to form a rivet bead. Moreover, a die button and a combination of a die button with a washer are claimed.
