ABSTRACT:
The metal yoke or mounting strap of an electric receptacle includes an integrally formed portion stamped from the central section and bent to extend toward the receptacle cover. The screw holding the wall plate in position extends through aligned openings in the plate and receptacle cover to contact the portion of the mounting strap, providing a ground path for the screw and the wall plate in units wherein the latter is also of metal. Several means of anchoring the screw are disclosed, including tapping of the receptacle cover opening and/or the mounting strap section, one or more stamped teeth on the integrally formed strap section, and the use of self-tapping screws. In any event, significant cost savings are realized by elimination of the useful, internally threaded rivet or eyelet positioned in the receptacle cover opening and extending to contact with the mounting strap.
