DUAL HEAD FASTENER ABSTRACT OF THE DISCLOSURE A fastener element adapted for use as a bolt head, nut and the like. The element includes an operative structure adapted for removable interconnection with at least one other element of a fastener assembly to complete the assembly. A head extends from the operative structure and has an exterior surface adapted to be removably engaged by a wrench for rotation of the element. The head is hexagonal in configuration and has a projection extending from each side of the head a predetermined height less than the height of the head and being circumferential ly aligned to thereby cooperate with the edges of each adjoining pair of sides of the head to form a twelve point head portion at the location of the projections while retaining a six point head portion at the remainder of the head. Thus, the fastener element can be used with either a six point or a twelve point wrench.
