The invention relates to a fixing element, comprising a concentric front face forming a friction surface for friction welding joining to a planar component fixed against the rotational and axial forces acting on the component by the fixing element and with several radial beads on the front face. The beads are defined in the rotational direction by a front groove let into the friction surface, the beads only having a marginal axial projection relative to the friction surface and are provided with a scraper surface from which the scraped material is pushed into the front groove during the welding process.

The invention relates to a hole-forming and thread-forming screw (1) for screwing into a metal plate, said screw comprising a head (2) provided with a tool-receiving element, in addition to a threaded shaft (3) and a hole-forming part (4) which tapers off in the form of a cone. Ribs (6, 7) extend in a thread-type manner along the hole-forming part. The hole-forming part ends in a truncated rounded end piece (5), and the rounded ribs which only drive out the material of the metal plate are symmetrically arranged and have a pitch which is equal to a multiple of the pitch of the thread.
The invention relates to a hole-forming and thread-forming screw comprising a head provided with a tool receiving element, in addition to a threaded shaft, and a hole-forming part tapering off in the form of a cone and ending in a truncated end piece. Said end piece has a coaxial recess surrounded by an edge that has an outer diameter (d) which is between 0.25 and 0.75 times smaller than the largest diameter (D) of the hole-forming part.
The invention relates to a self-tapping drill screw (1) which can be screwed into a metal sheet (20) comprising a slotted head (2) and a threaded shank (3), a slightly tapered tapping part and a friction part (5, 8, 12) being slightly conical. The friction part comprises a radial shoulder designed as a hole and coaxially surrounding the conical part (7, 10, 13, 15, 17) and being attachable to the metal sheet (20), having a substantially larger diameter compared to the conical part and verging into the tapping part (14) via a rounded ring edge (14).
The invention relates to a U-shaped clamping piece for attachment to a panel provided with an opening, having two flat legs, connected by a yoke, with a nut part axially movably disposed between the two legs for receiving a bolt, said bolt penetrating the opening and one leg, wherein said nut part is non-rotatably held on the clamping piece by a lateral arm. The nut part is secured by its end in axially resilient manner to the leg facing away from the panel by means of a plurality of straps extending from the end of the nut part to the leg.
The invention relates to a rotationally symmetrical fastening element (1) with an axially central rounded-off tip (5) for a friction-welded joint with respect to a component of a flat form. The tip is adjoined by a conical circumferential surface (6), which goes over into a flute (7) for receiving material that is melted during the friction welding, and by a shoulder (9) which surrounds the flute, is set back axially from the tip and goes over into the friction-welded joint.

The invention relates to a tapping screw (1) having projections (5) on its screw thread (4), the rear flank (8) being provided, starting from the start of the screw thread, with protruding projections and the load flanks (9) forming a continuous smooth surface. The projections extend across the pitch peaks and the screw thread is provided with projections over its full length.
The invention relates to a method for producing hollow bolts (1) which comprise a longitudinal bore (6) and circumferential notches (11). The hollow bolts are provided with longitudinal grooves which extend between elevations that determine the bolt diameter while circumferential notches are rolled onto the hollow bolts encompassing the longitudinal grooves and the elevations. The cross section of the longitudinal grooves is selected such that some of the material that is displaced when the notches are rolled on flows into the longitudinal grooves.

The present invention relates to a sliding clutch made of plastic material, which is especially suitable for the use in adjustment drives for vehicular exterior mirrors. The sliding clutch thereby comprises a first clutch part and a second clutch part, wherein the first clutch part and the second clutch part abut one another with planar faces in such a way that they are into engagement with one another up to a maximum torque only because of static friction. In this way, a sliding operation without rattling noises can be guaranteed. For achieving this safety function by means of which no force or torque transmission occurs from a predetermined torque range, no further mechanical components or additional electrical controls are required.
