    • As formed from a predetermined length of carbon steel wire, such as AISI C 1062 steel wire or high-manganese carbon steel wire, in sequential forming, rolling, and austempering steps, a pin for axial, non-rotational penetration into a steel, concrete, or masonry substrate has a head, a tapered shank, a point having a tip, and a transition zone between the tapered shank and the head. The head has an outer diameter at least about 2.6 times greater than the initial diameter of the predetermined length wire. The smaller end of the tapered shank has a diameter about 0.6 times the initial diameter thereof. The larger end of the tapered shank has a diameter about 0.7 times the initial diameter thereof. The point is joined unitarily to the smaller end of the tapered shank and conforms exept at the tip, which is rounded, substantially to a tangent ogive, which is tangent to the tapered shank. The transition zone has a tapered portion with a smaller end joined unitarily to the larger end of the tapered shank and with a larger end joined unitarily to the head at a circumferential fillet. The larger end of the tapered portion of the transition zone has a diameter about 1.1 times greater than the initial diameter of the predetermined length wire. The axial length of the transition zone is less than about one half of the axial length of the tapered shank. The austempering step provides the pin with a surface hardness not greater than about Rockwell C 48 and with a core hardness in a range from about Rockwell C 48 to about Rockwell C 58.

    • A method of assembling roof decking to an underlying substrate comprises the steps of providing a pin having a shank portion and a head portion having a predetermined diametrical extent, and a washer, having a central aperture, disposed upon the shank portion of the pin such that the washer has a diametrical extent which is substantially the same as that of the pin head so as to cooperate therewith in guiding the pin when the pin is axially driven through a drive bore of a fastener-driving tool. The inner periphery of the washer central aperture is also provided with a plurality of concave pin-engaging surfaces which are angularly spaced from each other so as to encompass less than one-half of a complete cylinder, but not less than one-third of a complete cylinder, so as to limit potential damage to the shank portion of the pin when the washer is moved axially along the shank portion of the pin as the pin is driven into the substrate by the fastener-driving tool in order to secure the roof decking to the underlying substrate.
