Abstract
A method for making a plated spline nail includes plating an elongated wire with a corrosion resistant material, passing the wire through a forming machine having rollers configured with protrusions formed thereon and extending outwardly therefrom to form grooves in the wire. cutting the wire to a desired length and forming a head, and a point on the wire to form the nail. The nail may have ring shanks formed therein after the head and point are formed. A lubricant may be applied to the nail and/or the forming machine prior to forming the ring shanks and/or prior to passing the wire through the forming machine to form the grooves in the wire. A nail formed by pre-plating the wire, and a nail formed by the method are also disclosed.
