ABSTRACT:
A cage (28) constructed from a metal blank 26 for encompassing a plurality of nested conical washers (43) having a common threaded bore to form a nut (28). The cage side walls are free of separable openings (22) that would result in relaxation ("blossoming") of nut parts during nut tempering causing undesirable separation and misalignment of the nut threads.
