Abstract
A nail has a head, a penetrating tip and a shank extending from the head to the penetrating tip. The shank has a circumference and a longitudinal axis. A plurality of rows of deformations formed as teeth are formed 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 teeth are formed parallel to one another and formed at an angle of at least 50 degrees relative to a cross-sectional plane perpendicular to a longitudinal axis of the nail.
