Abstract:
An low-profile cam locking fastener assembly in which a locking nut is connected to a locking washer through a tubular skirt that extends from the nut opening. The skirt and nut opening are coaxial having contiguous inner surfaces that are threaded to receive a bolt or stud. The washer is mounted to the skirt so as to be rotatable with respect to nut as well as axially movable to a position in which cooperating cam elements on opposing faces between the washer and the nut are separated. The cam elements are arranged so that when the nut and washer are fastened down to a bolt or stud on a workpiece, the cam elements engage one another to substantially prevent the nut from loosening from the threaded bolt/stud.
