AbstractAn improved, one-piece, sheet metal nail having a generally cross-sectionally V-shaped shank portion and a head portion comprising extensions of the two legs defining the generally V-shaped shank portion which are folded inwardly at substantially right angles thereto is provided. One of said shank portion extensions will overlap the other of said shank portion extensions to provide a relatively easily produced head portion having improved strength characteristics. The extensions of the shank portion legs are of sufficient length to provide a head portion of sufficiently large area for driving of the nail and/or for providing a sufficiently large bearing surface to retain the member through which the nail is driven to the member into which the nail is driven.
