ABSTRACT:
A fabric fastener adapted for fastening a fabric to a framework, or a workpiece to a fabric covered framework, comprises a head and shank, and a sharp edged tip section. The tip section has an unthreaded angle side which intersects a threaded side to form the sharp edge. Preferably two prongs with a space therebetween and sharp edges facing the space are formed at the end of the tip. The sharp edges, particularly of the prongs, serve to engage and cut through the threads of a fabric so that the fastener does not become entangled in the fabric, thereby minimizing damage to the fabric and also minimizing cross-threading with a framework aperture into which the fabric fastener is fastened.
