A fastener assembly includes a row of fasteners having a head, a tip, and a portion of a shank coated with a polymer composition. The polymer composition includes a polymer material such as polyurethane and metal particles. The polymer composition is used to provide improved corrosion and ultraviolet radiation resistance when used with naturally corrosive or pressure preservative treated wood. The fastener assembly is coated with the polymer composition by vacuum coating a dispersion of the polymer composition in a solvent such as water and removing the solvent. Una ensambladura de sujetadores incluye una hilera de sujetadores que tienen una cabeza, una punta, y una porcion de un cuerpo recubierta con una composicion polimerica. La composicion polimerica incluye un material polimerico como poliuretano y particulas metalicas. La combinacion polimerica se utiliza para proporcionar la resistencia mejorada contra la corrosion y contra la radiacion ultravioleta cuando se usa con madera tratada naturalmente corrosiva o conservada por presion. La ensambladura de sujetadores se reduce con la composicion polimerica al recubrir al vacio una dispersion de la composicion polimerica en un solvente como agua, y eliminar el solvente.
