摘要： A fastener is embodied as a bolt having a shank with a threaded portion for introduction through an aperture in a work piece is disclosed. The fastener is divided into exposed and unexposed portions when used in the work piece. The fastener comprises a first coating formed on the exposed portion and a second coating formed on the unexposed portion. The first and second coatings are mechanically distinct from each other and substantially non-overlapping. The first coating provides a decorative coating on the fastener. The second coating provides a proper torque-tension relationship between the work piece and the unexposed portion. The second coating deposits relatively uniformly to ensure the unexposed portion will not become oversized. An auxiliary coating may further be applied to all or a portion of the unexposed portion, beneath the second coating. The fastener may also be embodied as a nut, a bolt-lock structure, or a lock nut.
