摘要：
A method for fabricating a threaded fastener having a discontinuous coating of a contaminant-inhibiting coating material. In a preferred embodiment, the threaded fastener is formed so as to provide a coated fastener with substantially coating-free crests. The article resulting from the fabrication method also forms a part of the present invention. The resulting threaded fasteners include electrically conductive portions, allowing use of the fasteners in fabricating structural assemblies using welding techniques.
