Abstract
A mounting screw for mounting an electrical wiring device having non-metallic components, to an electrical outlet box and combination of root electrical wiring device and screw. The screw includes a head and a shank, with a lip projecting downwardly from the bottom surface of the screw head spaced from and encircling the shank, and a series of ribs extending radially outward between the shank and the lip. Advantageously the mounting screw is in combination with an electrical wiring device having non-metallic mounting straps so that when the screw is installed by a power tool, the lip-and-ribs arrangement on the screw bites into the mounting strap material to produce resistance to the turning of the power tool signaling the operator that the screw is secure.
