Abstract: A self-punching functional element serves for the fastening to a workpiece and comprises a head part that has an abutment surface for introducing a punching force directed in a punching direction into the functional element and a rivet section that extends away from the head part in the punching direction and that comprises a free end that is provided with a first punching edge for punching a slug out of the workpiece. The functional element further comprises a functional section that has a punching pilot that is radially surrounded by the rivet section, that extends away from the head part in the punching direction, and that has a second punching edge for punching a hole into the slug. The second punching edge is set back with respect to the first punching edge in the punching direction.

Abstract: The present invention relates to an apparatus for fastening a functional element to a section of a workpiece and/or for reshaping a section of the workpiece, said apparatus comprising a support device for supporting the workpiece, wherein the workpiece section has a first surface facing the support device and a second surface facing away from the support device. The support device comprises a first support element having a first workpiece support surface that is associated with the first surface, and a second support element having a second workpiece support surface that faces away from the first workpiece support surface and that is associated with a supporting surface. The first and the second support element are movable relative to one another by means of a spreading device such that the first and the second workpiece support surface can be moved away from one another in an axial direction, in particular wherein the axial direction extends perpendicular to the first and/or second workpiece support surface.
