ABSTRACT:
A plastic accessory having a retaining socket for use with socket head cap screws, the plastic accessory engagingly receiving the head of the screw and having a hub concentrically positioned within the retaining socket and co-axial with the socket. The retaining socket of the plastic accessory is shaped to allow for engagement with the socket head cap screw and the hub of the plastic accessory extends into the socket of the head in the screw. The upper body portion of the hub, upon engagement with the screw, is both sheared and reshaped to a configuration corresponding to that of the head socket of the screw. A plurality of primary grips and a plurality of secondary grips are positioned on the inside wall of the retaining socket of the plastic accessory for absorbing the screw head tolerance and gripping the peripheral surface of the head of the screw. The screw head is resiliently received by deforming, shearing and press fitting the retaining socket of the plastic accessory.
