This nut torque indicator cover includes a cover piece that is joined to an indicator piece. It is fastened to a nut/bolt assembly primarily by pressing it down onto and over the exposed threads of the bolt so that the indicator piece registers with the hex portion of the nut. A snap fit design is incorporated into the nut torque indicator cover such that the cover piece and indicator piece can rotate relative to each other. The cover piece fastens securely to the external threads of the bolt providing protection to the threads, while the indicator piece, secured by the hex flats of the nut, indicates the nut circumferential position, allowing an indication of any torque loss.
