Abstract
A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied.
