Abstract
A direct fastening fastener particularly suited for use in normal weight or lightweight composite deck system. The fastener is heat treated to a dual-hardness level so that a portion of the fastener is capable of driving into the support member, such as a joist and a decking member. The remaining portion of the fastener remains relatively ductile so that it can withstand and transfer shear loads imposed by shifting of the concrete slab, which overlies the composite decking, to the support member. The fastener can be a single or multiple piece fastener which includes specially formed annular flanges that enhance interlocking between the fastener, the concrete slab and support members.
