ABSTRACT:
An improved sheet metal nail utilizing a protrusion, or protuberance, aligned with the locking tangs and interposed the tangs and the leading edge of the nail is provided. The protrusion enters the media into which the nail is driven prior to entry of the tangs and thus provides a lead hole for the tangs to minimize damage thereto during the nail driving operation.
