Abstract:
A device for fastening side impact supports, and door or flap hinges (10) to the doors (12) or flaps or to the bodywork of motor vehicles, with a screw (141) which extends through an opening in the door (12), the flap or the bodywork sheet and through an opening in the side impact support or hinge (10), and is secured by a nut (16), in which a hollow absorber element (18) is arranged between the nut (16) and the sheet of the door (12), the flap or the bodywork or the side impact support or the hinge (10), which absorber element is penetrated by the screw (14') and has side walls (20) which run substantially parallel to the axis of rotation of the screw (14'), and two abutment surfaces (22, 26, 34) each running perpendicularly to the axis of rotation of the screw (14'), wherein the one abutment surface (26, 34) is supported on the sheet of the door (12), the flap or the bodywork or the side impact support or the hinge (10) while the other abutment surface (22) bears the nut (16). The invention also relates to similar devices in which an inner thread is provided on the absorber element instead of the nut.
Abstract:
A self-tapping screw (10) having a head (12) and an outer thread carrier (16) with an end (20) at which the outer thread (18) has an outer diameter decreasing towards the end (20), at least over a part (K) of the length thereof ending at the end (20), and the outer diameter of the outer thread (18) decreases according to the draft angle of holes in which the screw (10) is to be set.
Abstract:
The invention relates to a self-locking nut (10) having an internal thread (12) with a core hole which has one or a plurality of regions (14) having a reduced internal diameter.
