Abstract
A fastener, for connecting a first component having a first hole to a second component having a second hole, includes a cage which is fitted at its end with a radial flange and further a cross-sectionally rectangular or square shank segment. This shank segment is insertable into the second hole of the second component, for resting against the associated side of the second component. A nut is at least partly axially received in the cage and is rotatable from a first rotational position in the cage into a second rotational position. The nut has an axial borehole to receive an affixation screw and also comprises at its outside the diametrically opposite wing elements, where, upon rotation of the nut from the first into the second rotational position, the wing elements will be pulled on account of the affixation screw's rotation in the nut against the other side of the second component, with a head of the affixation screw resting against the first component and compressing latter against the cage flange. The cage and nut are made of molded plastic. The hole is square or rectangular. The wing elements of the nut are situated in the first rotational position within the contour of the cag…
