ABSTRACT:
A laminated nut composed of laminations of tapped conical spring washer segments in which at least one of the segments has a different load-deflection ratio than another segment, thereby to provide for more uniform loading of the threads on the laminated segments, and to provide for self locking of the nut on the bolt by thread interference. A lock mechanism is also provided that automatically and positively locks the nut to the associated bolt, as is required for safety purposes and to avoid legal charges of product liability.
