Metallics JBRMNW48M Screw 10-32 x 3/4 Round Head Combina (Jar 1000)

No. Device ears on receptacles and switches are tapped 6-32, and cover plate screws are usually 6-32 as well. A 10-32 screw will not thread into them. 10-32 is the box and ring thread, used for grounding screws and for fastening straps, rings, and covers to the box body itself.

It is a combination drive, so the head is slotted and Phillips in one recess. You can run it with a flat blade or a #2 Phillips, which is handy in a panel or box where you already have one screwdriver in hand. Head style is round, so it seats on top of the material rather than countersinking flush.

1,000 screws per jar, packaged as a jar rather than a box, which is the shape most electricians keep on the van or at a bench. Model number to order is JBRMNW48M. For a maintenance crew or a rough-in crew standardizing on one device screw, a single jar covers a lot of openings.

For a plain device-to-box attachment with no ring, 3/4 inch is longer than needed and you will have thread standing proud behind the strap, though it does not hurt anything on an open box. Where 3/4 inch earns its length is through a plaster ring or an extension ring, or when the device sits forward of the box face. If you are only ever fastening flat to the box ears, a 1/2 inch 10-32 is the tidier choice.
