Self-Expanding Fasteners

Foilgard fasteners offer a self-expanding shank that ensures positive contact with plated through-holes and eliminates the risk of shaving the plating out of the hole. Gripping teeth allow the fastener to yield high torque-out and the flared shank allows high pushout performance. Foilgard fasteners are easily installed by inserting the shank of the fasteners into a punched or drilled hole and squeezing the fastener using a flat punch and anvil. Sufficient force is applied so that the projecting knurl teeth are embedded and the inside shoulder of the knurl contacts the board. The shank expands outward to complete the installation. The fasteners are available in thread sizes from #4040 through # 1 0-32 and M3 and MS and in various lengths.
