ABSTRACT:
A cover for the end of a bolt to which a nut is attached is provided. The cover includes a body having an open end which is communication with an internal cavity. The internal cavity includes a first section of the shape of the nut and a second section. The second section of the internal cavity is cylindrical and is of a diameter between the outer and inner thread diameters of the bolt. In operation, the cover is forced over the bolt and nut such that the first internal cavity section surrounds the nut and the second internal cavity section engages the threads. By virtue of the interference fit provided, the cover may not readily be removed.
