ABSTRACT:
A protective and decorative cover for application to bolts, nuts and the like. The cover comprises a retainer made of a resilient compressible material having legs which align with the flats of a bolt head or nut. A generally cylindrical cap is then applied over the retainer. The internal diameter of the cap provides an interference fit with the legs of the retainer thereby compressing them against the flats of the bolt or nut. The exposed head of the bolt or the nuts is thus fully enclosed by the cap and protected from the elements. The cap may have a decorative shape and finish that is particularly desirable in automotive, motorcycle and marine applications.
