ABSTRACT:
The invention relates to a plastic nut for mounting on a component having a penetration, said plastic nut being insertable into the penetration with a nut piece having a receiving hole for a screw and being provided with a flange for contact with one side of the component and with snap-on hooks for contact with the other side of the component, said snap-on hooks securing the plastic nut to the component, wherein, when in the relaxed position, said snap-on hooks on the one hand conform in their radial extent to the internal dimension of the penetration and on the other hand cover the receiving hole and spread apart when the screw is inserted and position themselves opposite the component. Disposed next to the snap-on hooks are walls extending in the spreading-apart direction, said walls extending from the flange to the nut piece and having reductions of their wall thickness—such thickness reductions extending in the central region thereof and in the spreading-apart direction—such that, when the screw is tightened, through bending of the walls at the thickness reductions the flange and the snap-on hooks contact the component on both sides.
