ABSTRACT:
A V-nail fastener has a leading edge that is partially formed with asymmetric sharpening, limited substantially to the central sections. Flange elements extend generally perpendicularly to the panel elements of which the central (V-shaped) portion is constructed and cooperate therewith to give the fastener a W-shaped overall profile. The lateral sections of the leading edge, which extend along the flange elements, are substantially devoid of sharpening, or are otherwise so formed as to permit the directional influence of the asymmetric sharpening to occur substantially undiminished.
