Abstract: A fastening element for fastening a base plate on a substructure having a web-shaped edge region includes a rotary drive and a screw spring element formed from a spring wire. A rotational axis of the rotary drive and a spring axis of the screw spring element are coaxial. The fastening element having a shank to which the screw spring element is fastened with a first end of the spring wire. The screw spring element is rotated about the spring axis via the rotary drive. The opposite free end of the screw spring element having, as a threading aid, a pitch widening which grips the web-shaped edge region of the substructure upon rotation and clamps the edge in the screw spring element upon further rotation.

Abstract: A package packages a variety of point hooks having angled tips, which are to be applied by a nailing machine.
