Metallics TM63LP 6-32 x 1 in. Truss Head Combo Receptacle Screws - Steel Zinc - Each

Yes. The TM63LP is a 6-32 thread, which is the standard machine screw thread used on receptacle and switch mounting yokes and on device box ears in North America. Length is 1 inch, so it gives you extra reach when a device sits proud of a recessed box or behind a thick plaster ring.

Standard device screws run about 1/2 inch, so 1 inch is the long version, sold for deep-set boxes, thick mud rings, and stacked plaster rings where a short screw will not catch the yoke. On a flush box it simply bottoms into the box ear with thread to spare, which is harmless, or you back it out and use a shorter screw if the point would contact a conductor.

Either one. The truss head is a combo drive, slotted plus Phillips, so a #2 Phillips or a standard flat blade both seat. That matters on a device box where you are working one-handed in a panel and only have the screwdriver already in your hand.

A truss head is wide and low profile, so it spreads bearing load over the yoke slot and sits flatter under a wall plate than a taller oval or pan head. On receptacle and switch mounting where the plate has to close down tight, that lower crown is the reason to pick it.

The TM63LP is steel with a zinc plating, which is a general indoor corrosion coating, not a marine or wet-location finish. It is fine for interior device boxes, panel interiors, and dry MRO work. For exterior, washdown, or coastal openings, specify stainless 6-32 machine screws instead.

Yes, the TM63LP is domestically made, which is what lets it clear Buy American style sourcing language on government, school, and healthcare jobs where a fastener line item still has to carry a domestic origin.

No options to pick. The TM63LP is a single configuration, 6-32 by 1 inch truss head combo in zinc plated steel. If you need a different length or a different thread, that is a different Metallics part number, not an option on this one.
