Metallics RM8810M Screws 8-32 x 1-1/2 RH CD MS St-Zn (10000 pcs)

Yes. 8-32 is the standard machine screw thread for outlet and switch boxes, device mounting ears, and cover plate straps in US electrical work, so the RM8810M threads into those tapped holes directly. The 1-1/2 inch length is longer than the typical short device screw, which is what you want when you are reaching through furred-out plaster, tile, or a mud ring.

Round head with a combination drive, so you can run them with either a flat blade or a Phillips bit. No special driver needed. The round head sits proud of the surface rather than countersinking, so it is not the screw to use where you need a flush face.

Carbon steel with a zinc plating. That is a general indoor, dry-location fastener. For wet, washdown, or coastal exterior work, specify a stainless 8-32 instead, since zinc plating on steel will eventually corrode in those conditions.

10,000 pieces. This is a bulk contractor and MRO quantity, aimed at crews doing repetitive device and box work or shops that want one bin stocked for the year, not a one-off repair purchase.

No. It is a machine screw, not a self-tapping or drywall screw. It needs a pre-tapped 8-32 hole or a matching 8-32 nut, clip, or captive strap to hold. For sheet metal with no tapped hole, use a self-drilling tapping screw or add an 8-32 speed nut.

The RM8810M at 1-1/2 inches is the long version, meant for deep reach. For flush device mounting in a standard box, step down to a shorter 8-32 round head machine screw, commonly 1/2 or 3/4 inch, in the same Metallics zinc plated steel line. The thread is identical, only the shank length changes.
