Abstract: A gun assembly for bonding a fastener to a workpiece is disclosed which uses heat induction to fuse a thermoplastic adhesive coating on the base of the fastener to the workpiece. The gun assembly has a head member of electrically non-conducting material. A hollowed core electrical conductor is embedded in the head member in a spiral configuration adjacent the surface of the forward end of the head member. Seating means are provided on the forward end centrally of the spiral configuration for receiving the fastener to be applied to the workpiece. An air conduit extending through the head member between its forward and rearward ends is in communication with the seating means. A flux concentrator plate is mounted on the forward end of the head member and surrounds the seating means. A body member slidingly supports the head member and is selectively moved between a retract position and a workpiece engaging position by a piston and cylinder drive means.

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.
