Abstract: A cap device for covering the exposed sections of a nut and bolt assembly and preventing oxidation of those exposed sections. The cap device incudes at structure having a first end that is opened and an opposite second end that is at least partially opened. The cap structure defines a chamber in between the first end and the second end that is sized to receive a nut and a segment of a bolt that extends through the nut. The chamber inside the cap structure is at least partially filled with a viscous material that creates an air impervious seal between the cap structure and the nut and bolt assembly. As the cap structure is advanced over a nut and bolt assembly, the viscous fill material is displaced from the chamber through the second end of the cap structure. Once fully seated, a closure element is used to seal the second end of the cap structure. The presence of the closure element creates a vapor lock type of seal that helps retain the cap structure in place.
