1. A self-punching functional element for fastening to a workpiece, said self-punching functional element comprising
a functional section; and
a fastening section that has
a contact surface for an engagement of a setting device,
an end face remote from the contact surface, and
an outer peripheral surface connecting the contact surface and the end face,
wherein the end face is radially outwardly bounded by a punching edge for punching a slug out of the workpiece, and wherein at least one projection is provided at the outer peripheral surface adjacent to the contact surface, said projection rising from the outer peripheral surface in a radial direction and extending further outwardly in the radial direction than the punching edge and, wherein the projection is continuous in the peripheral direction.
