ABSTRACT:
A self-threading polymeric fastener and blank therefor which can be used, for example, to support a wall plate over an electrical outlet or switch. The fastener blank comprises three portions, all integrally molded together, including a slotted head, a substantially cylindrical shank and a tapered tip. A helical thread is formed on the shank and tip by deforming the outer surfaces thereof without removing any significant amount of polymeric material therefrom. This is accomplished by rotating the tip and shank in a helically threaded bore, such as that provided in an outlet or switch. The polymeric fastener blank can be integrally molded with a polymeric wall plate to make their colors identical.
