Metallics JTM63 6-32 x 1 in. Truss Head Combo Receptacle Screws - Steel Zinc - Each

Yes. The JTM63 is a 6-32 thread screw, which is the standard machine screw thread used on receptacle and switch mounting yokes and on device plates in North America. At 1 inch long it threads through the yoke and into the box ear with room to spare.

The extra length is what gets you through added depth. Device screws packed with a receptacle are usually around 1/2 inch, which runs short once you are mounting through a thick wall plate, a plaster ring, a mud ring, or a box set back from the finished surface. The JTM63 gives you a full 1 inch of 6-32 thread to reach the box ears in those cases.

Truss head is the wide, low profile option, and that is why it is used on electrical devices. The broad bearing surface spans the slot in a device yoke or a ground clip without pulling through, and the low crown keeps the head from standing proud behind a wall plate. A pan or round head sits taller and bears on less area; an oval or flat head needs a countersink the device does not have.

They are zinc plated steel, so the plating gives moderate corrosion resistance for dry and normally damp interior work. For sustained outdoor exposure, washdown areas, or coastal humidity, specify a stainless 6-32 device screw instead, since zinc plating on steel will eventually rust through in those conditions.

They ship in a jar, which is how most contractors want a device screw stocked, scoopable at the bench or in the van rather than loose in a bag. Model number to order against is JTM63.

Not well. Decorative and standard wall plates use 6-32 screws too, but a 1 inch length is far longer than a plate needs and the truss head will stand above the plate face. Use the JTM63 for mounting the device to the box and a short 6-32 oval head screw for the cover plate itself.
