ABSTRACT:
A combination of deformations on a single nail shank provides a nail with optimal withdrawal performance and shear slip resistance. In particular, a nail has a head, a tip, and an elongate shank with a first deformation and a second deformation. The first deformation is positioned closer to the tip. When the nail fastens a first substrate to a second substrate, the first deformation is positioned completely in the second substrate to provide withdrawal resistance from the second substrate. The second deformation intersects the plane between the first and second substrates to provide resistance to shear slip. Moreover, the second deformation makes contact with the inner surface of the bore created by the first deformation.
