The invention relates to a device for fastening an add-on (21) and a support (20) at a distance from each other, comprising a plastic mounting nut (1), a plastic compensating bush (5) and a fastening screw (14) having a screw shank (15) from a hard material. A threaded arrangement (8, 9) having a first direction of thread is configured between the mounting nut (1) and the compensating bush (5). The screw shank (15) has an external thread (17) having a second direction of thread opposite the first direction of thread which is used to produce an internal thread in a channel section (12) configured in the compensating bush (5). When the fastening screw (14) is screwed in, the compensating bush (5) is automatically screwed out from the mounting nut (1). |
