Disclosed are a method and a device for mounting a fastening element ( 12 ) to a part ( 13 ), e.g. a sheet metal part, said fastening element comprising a head piece ( 14 ) with a tubular rivet section ( 16 ) which is disposed concentric to an axis of symmetry ( 18 ) of the fastening element ( 12 ) or a fastening section ( 20 ) of the fastening element ( 12 ) and extends into the head piece via a radially extending contact surface ( 22 ). The rivet section ( 16 ) is guided through the part ( 12 ) so as to form a hole in said part, and the rivet section ( 12 ) is flanged such that the part is clamped between the contact surface and the flanged rivet section in the area of the hole. The inventive method and device are characterized in that the part is placed above a rivet matrix, and the rivet section is pressed through the part and is then flanged by applying a local force to the head piece of the fastening element, said force moving in circles about the central axis of symmetry, or by applying such a force to the matrix while performing a relative axial advancing movement between the tool applying said force and the matrix.
