Abstract: A polymer-coated metal fastener is provided which has both improved ease of drive into a substrate, and improved resistance to withdrawal from the substrate. The coated fastener is prepared by heating a metal fastener, or a portion of it, to about 400-2000° F. and cooling in an aqueous medium containing an acrylic or modified acrylic polymer. The rapid cooling causes formation of a thin yet durable polymer coating on the fastener.

Abstract: A selectively hardened nail includes a nail head, an elongated shank, and a tip. A portion of the nail shank is made harder than the remainder by selectively heat treating that portion, and cooling it. The nail has controlled bending properties. The selectively hardened portion does not significantly bend when the nail is fired at a surface using a power driving tool, or during use of the nailed object.

Abstract: An angled strips of brads with a plurality of cohered brads having a shank with a tip portion. A head portion of at least some of the plurality of brads having a bulge protruding forwardly from the leading side thereof and extending at least partially into the trailing side of the head portion of an adjacent brad. An upper leading side portion of the head portions of the plurality of brads offset rearwardly of the leading side of the shank, whereby interlocking of adjacent head portions of the angled strip of brads is reduced. The rearwardly biased head portion is formed preferably with a rearwardly sloped riser portion of a header punch.

Abstract: A method and apparatus for providing a coating on the exterior surfaces of a plurality of elongate members, such as wires, including positioning a plurality of elongate members substantially parallel to each other, coating the exterior surfaces of each member with a coating, removing any excess coating from desired portions of each member and curing the coating to adhere the coating to each member.

Abstract: A steel fastener has an elongate shank, an enlarged head formed at one end of the shank, and a generally pointed tip formed at the other end of the shank. A grooved portion of the shank is formed with helical grooves defining helical ribs and with annular grooves defining annular rings. The shank has a cylindrical portion between the grooved portion and the tip and a cylindrical portion between the grooved portion and the head. Each of the annular grooves has a root where deepest and each of the annular rings has a crest where largest. The roots define an imaginary cone diverging toward the tip. The crests define an imaginary cone converging toward the tip. The shank has an exterior surface coated with a polymeric coating, which is formed from an aqueous composition containing a water-based acrylic resin and a water-based polyurethane resin. A zinc layer and a chromate conversion layer are provided between the polymeric coating and the exterior surface of the shank.

Abstract: A fastener assembly, such as a nail assembly, includes a row of fasteners held together and maintained in position by an extrudable thermoplastic adhesive composition containing a particulate filler, an extrudable thermoplastic resin reacted with a polar compound, and optional quantities of an additional thermoplastic resin. The adhesive composition provides the fastener assembly with increased rigidity, reduced bending and buckling, and reduced shearing requirements for separating an individual fastener from the row. The invention also includes an adhesive composition useful in the fastener assembly.

Abstract: A corrosion-resistant, headed fastener, such as a nail for exterior applications, is made from a carbon steel wire pre-coated with a protective, metallic layer having corrosion-resistant properties, the protective, metallic layer being discontinuous at a region on a leading end of the pre-coated wire. After at least part of a protective, metallic cap having corrosion-resistant properties is disposed near the leading end of the pre-coated wire, at least part of the protective, metallic cap is welded to the leading end of the pre-coated wire so as to cover the region where the protective, metallic layer is discontinuous, by impact welding, as a fastener is formed from the pre-coated wire in such manner that the fastener is formed with a shank and with a head, which is formed by deformation of the leading end.

The composition comprises a mixture of a copolymer of an aromatic monomer, preferably styrene, and a monomer with .alpha., .beta. unsaturation with carboxyl groups, preferably maleic anhydride, and a thermoplastic resin disposed within an organic solvent. The resin is preferably polyvinyl acetate, and the solvent can be an aromatic solvent, a ketone, a chlorohydrocarbon, or a mixture there of. The coating composition is disposed within a reservoir, and the fastener is dipped into the composition within the reservoir. The coated fastener is then subsequently dried at approximately ambient temperature.
