ABSTRACT:
A wire nail for use with a powered nail-driving tool has a full-round head with an axis that is offset from an axis of the integrally formed shank. An outer circumferential surface of the shank is at least as offset from the shank axis in one radial direction as a circumferential surface of the head in that radial direction. Accordingly, such nails may be collated shank-to-shank in a strip of wire nails such that adjoining shanks are both parallel and touching. During manufacture of the wire nail, a notch is formed in the shank at the intersection between the shank and the head. The notch and the head axis are disposed on opposite sides of the shank axis from each other. The notch facilitates improved metal flow during the head-forming procedure and results in strong shank to head connections.
