Proposed set of tools neatly dimple cup washer to prevent screw from turning in mounting hole. Two dimples required, one leaning outward to grip recess in mounting hole and one leaning inward to grip recess in screw-head. Tools do not cause cracks and tears. Substitute die-forming process for hammer-and-center-punch process. De-forming process requires less skill and gives results of greater quality and consistency.
