Case 3652 IMPROVED PLASTIC HEADED FASTENER ABSTRACT There is disclosed an improved fastener of the type having a head portion, a shank portion extending from the head portion, and a plastic cover overlying the fastener head. The head includes an outer perimeter of generally square configuration having a plurality of substantially straight side portions. The upper surface of the head is provided with an oversized drive recess which extends along the diagonals of the square perimeter. As a result, the fastener head may be readily aligned within a mold which forms the plastic head cover. More particularly, anyone of the straight side portions may engage an alignment surface of the mold to permit the final drive recess forming portion of the mold to be readily aligned with and received by the initial over sized drive recess. The resulting plastic cover entirely overlies the fastener head and the thickness of the plastic within the oversized recess reduces the drive recess dimension to a final desired size.
