586054 A nail comprising a head, a penetrating tip, a shank extending from the head to the penetrating tip and having a circumference and a longitudinal axis, and a plurality of rows of deformations in the shank extending outwardly of the shank. The rows are formed in a spiral pattern along the length of the shank from about the head to about the penetrating tip, the rows of deformations being formed parallel to one another and formed at an angle of at least 50 degrees relative to a perpendicular to a longitudinal axis of the nail. The deformations are formed as teeth extending outwardly from the shank and are formed with a leading portion tapering toward the penetrating tip and a trailing portion having an interference surface oriented toward the head, opposite the leading portion, and wherein the teeth overlap one another at adjacent leading ends and trailing ends.
