Abstract
A pair of nut locking cups are engaged on the external surfaces of a pair of nuts and are constructed so that the outside radius of a cup is equal to one-half of the distances between adjacent studs to allow the cups to be placed on the nuts regardless of nut position with the outside radii of the cups remaining in contact with each other; a locking bar is positioned across the two adjacent studs with the studs being welded to the bar; the locking cups are also welded to the locking bar and thus form a positive lock between the studs and the anchor point for the nut lock cups.
