Fastening has an anchor nut and a holder profile with wedge clamping slits to take the straps of the holder profile when pressed together in a firm hold with high gap tolerances even with a low-profile anchor nut

摘要

The fastening has an anchor nut (1), holder profile (3) and a press system (7-9) to press the straps (2) of the holder profile (3) into the two tapering clamping slits (15) in the anchor nut (1), with wedge clamping surfaces. When in the clamped position, the clamping surfaces grip matching side surfaces (2a,2b) of the straps (2). The clamping slits (15) have chamfered surfaces at the opening, to form a wedge-shaped entry with a larger opening angle than the wedge taper at the clamping zone.
