ABSTRACT:
The invention relates to a plastic nut to be fitted to a component having an aperture, which, with a nut piece serving to hold a screw, can be plugged into the aperture and which, in order to bear on one side of the component, is provided with a flange which has a through hole for the screw and, on its side facing the component, has a sealing washer and, in order to bear on the other side of the component, is provided with snap-action hooks which, after insertion, spread out as the screw is tightened in the accommodation hole in the plastic nut and therefore secure the plastic nut to the component. The sealing washer has at its outer rim a shoulder which encloses the flange and projects beyond the thickness of the latter and, from its inner rim, merges into a collar which projects into the through hole.
