ABSTRACT:
A vehicle plastic panel is mounted by means of a one-piece molded screw anchor on a substructure member in a bi-directional tolerance compensating manner. The screw anchor is adapted for snap-in capture in a substructure elongated rectangular aperture enabling it to slide along the aperture major axis. Upon the insertion of a self-tapping screw in a panel circular opening overlying the screw anchor, the screw tip enters the anchor upper lead-in chamber. If the screw and anchor are misaligned, the screw tip contacts a subjacent one of a pair of opposed anchor ramped side surface portions whereby the anchor is cammed for limited adjustment along the aperture major axis. The anchor ramped surface portions terminate in a lower, elongated channel extending transverse to the major axis. The anchor base wall is adapted to be threadably engaged upon driving the screw at a piercing point in vertical alignment with the panel opening.
