A sub-assembly consisting of a synthetic plastic hub cover, separate fastener members, and a gasket improves efficiency in the production line mounting of hub covers to vehicular wheel ends. In a preferred form, each sub-assembly incorporates a plurality of fasteners (i.e. mounting bolts), lock washers, and a gasket, all secured to a moldable cover. The cover includes a plurality of cylindrical mounting apertures, each aperture containing an integrally molded segmented, tapered flange of a predetermined thickness. In a preferred embodiment the segments are designed to elastically flex upon insertion of a fastener through the aperture for retaining the fastener within the aperture. The gasket is retained against the cover via shafts of the bolts.

In a hub cover adapted for securement to a vehicular wheel end, said cover formed of a moldable material and including at least one cylindrical aperture defining an axis, and a threaded fastener comprising a shaft with threads having a defined root diameter, said fastener extending through said aperture for securement of said cover to said wheel end; an improvement comprising: said aperture comprising an integral flexible flange at one axial end of said aperture, said flange integrally attached to the cylindrical wall of said aperture, said flange comprising spaced segments extending orthogonally to said axis, said segments defining a lead-in hole for said fastener, said segments defining a plurality of V-shaped spaces between adjoining segments, the thickness of each segment being tapered such that the greatest thickness of each segment is at its integral attachment to the aperture wall, and wherein said lead-in hole comprises an undeflected diameter substantially equal to the root diameter of said shaft; whereby upon insertion of said fastener, said segments are axially deflected to permit axial passage of said fastener through said aperture, whereby said lead-in hole enlarges to enable said threads of said fastener to pass into and through the aperture.
