Metallics RM87M Screws 8-32 x 1-1/4 RH CD MS St-Zn (1000 pcs)

Yes, as long as the tapped hole is 8-32, which is the standard thread on device boxes, plaster rings and fixture straps. The 1-1/4 inch length gives you room to pass through a strap plus a canopy or bracket and still engage the threads. If you are only fastening a cover plate flat to a ring, that length is longer than you need and a shorter 8-32 is the cleaner choice.

It is a machine screw (MS), meaning a uniform straight thread that requires an existing tapped hole or a nut. It will not cut its own threads in sheet metal. If you need a fastener that forms its own thread in an untapped hole, you want a self-tapping sheet metal screw, not this one.

Round head with a combination drive, so the same screw takes either a flat blade or a Phillips driver. The round head seats on top of the surface rather than countersinking, which is what you want when you are fastening through a strap or bracket and not into a chamfered hole.

They are steel with a zinc plating. That covers normal dry interior electrical work, boxes, covers, straps and fixture mounting. For wet locations, exterior work or corrosive environments, spec a stainless fastener instead rather than relying on zinc plating.

Each RM87M box holds 1,000 screws. That is a bulk contractor pack, sized for a shop or truck stock rather than a single opening, so an electrician rough-in crew or an MRO storeroom standardizing on 8-32 hardware is the usual buyer.
