Smooth nails and screw nails coated with adhesives or paints based on vinyl and polyvinyl acetate (mixtures of vinyl and polyvinyl acetate) or water-soluble thermoplastic resins (eg acrylic resins) are known. The pull-out strength (i.e., nail retention strength) of these nails is approximately 10

れない欠点がある。[0003] According to conventional coated nails, a thermoplastic resin paint or adhesive is applied to the shank portion, which remains in its surface state after the nail making process. Therefore, while the coated nail is penetrating into the nail driving material, due to the friction between the nail driving material and the shank of the coated nail,
Since the resin coating is scraped off, there is a drawback that the drawing strength, which is one purpose of the coating, cannot be sufficiently improved.

It is characterized by consisting of a thermoplastic resin coating applied to the entire surface of the shank.

に対する３０年保証の要求にも十分応えられる。According to the present invention, the unevenness on the surface of the shank of the nail is large enough to become entangled with the fibers of the nail driving material, so that during nail driving, the unevenness on the entire surface of the shank can be prevented. This protects the coating from being scraped off due to friction between the nail driving material and the shank, and the coating is well maintained over almost the entire surface of the nail shank even after nail driving is completed. For this reason, the coating that melts due to frictional heat during nail driving intertwines with the fibers of the nail driving material and exerts an adhesive action, greatly improving the nail's holding power. As a result, for example, the requirement for a 30-year guarantee on nail retention can be fully met.

The surface of the nail is dissolved, a compound of phosphoric acid and nail material is formed on the surface of the nail, and the surface of the nail is roughened. As a result, unevenness as shown in FIG. 1 is formed on the surface of the shank portion of the nail. The surface characteristics of the shank portion of this nail can be understood by comparing them with the surface characteristics of the shank portion of a nail that is not subjected to chemical conversion treatment immediately after nail manufacturing, as shown in FIG. The surface of the nail shank shown in FIG. 2 is smooth except for the presence of microcracks here and there.

％の引抜き耐力向上を達成した。As mentioned above, nails exhibit a rust-preventing effect by being subjected to chemical conversion treatment using a phosphoric acid solution, and the surface of the nail is dissolved and roughened. By coating the roughened shank of the nail with a thermoplastic resin, the thermoplastic resin coating becomes entwined with the unevenness of the shank surface, allowing the coated nail to drive into the nail driving material (for example, wood). The thermoplastic resin coating does not scrape off from the surface of the shank portion during the nailing process, and remains dispersed over the entire surface of the shank portion of the coated nail even after nail driving is completed. Therefore, when the nail driving material is wood or other fibrous material, the thermoplastic resin coating melts due to friction during nail driving and entangles with these fibers as an adhesive, improving nail pullout strength. It seems to be. As a result of experiments, coated nails treated with the chemical conversion treatment of the present invention have a 50%
