Abstract
The conduit body assembly includes a metallic conduit body having an open upper end and a metallic cover removably positionable over the upper end. A metallic threaded fastener secures the cover to the body. The metallic fastener includes a threaded post and a nut removably attached to one end of the post. The nut and the post are formed of similar non-corrosive materials so as to resist corrosion therebetween. The nut is removable from the post in an environment where corrosion between the metallic fastener and the conduit body and cover prevents removal of the threaded fastener therefrom. Removal of the nut from the threaded post permits removal of the cover from the conduit body.
