Metallics JSRM1461 10-32 x 2 in. Round Head Slotted Machine Screws - 316 Stainless - Each

Yes. 10-32 is the standard machine screw thread used for grounding and device mounting holes in steel outlet boxes, mud rings and plaster rings, so the Metallics JSRM1461 screw threads straight into those tapped holes. The 2 inch length is well past a standard device screw, so it is intended for deep mud rings, thick wall build-ups, or stacking gang covers and spacers.

They are made of 316 stainless, the marine grade alloy that holds up better than 304 against chlorides, so coastal, wash-down and damp exterior locations are exactly what it is for. Pool houses, marinas, food processing areas and roof-mounted enclosures are typical uses.

A flat blade screwdriver. The head is a round head with a single slot drive, not Phillips and not combination, so no Phillips or square bit will seat in it.

Round head sits proud on the surface with a domed crown and a flat bearing face underneath, so use it where the hole is not countersunk and you want the head to clamp a plate or strap on top of the material. If the part has a chamfered or countersunk hole and the head has to finish flush, a flat head machine screw is the one you want instead.

These are machine screws, not self-tapping or sheet metal screws. The 10-32 thread needs a mating tapped hole or a 10-32 nut, so for through-bolting an untapped enclosure wall order 10-32 nuts separately, in 316 stainless if you want to keep the corrosion rating consistent.

They come in a jar, which is how Metallics packs its loose fastener counts for bench and van stock. Handy if you are restocking a service truck rather than pulling a single screw.

Mechanically fine, but be aware that stainless against aluminum in a wet or salt-air location sets up galvanic corrosion of the aluminum. Dry indoor use is a non-issue; for exposed coastal work use an isolating washer or a sealant at the joint.

Metallics part number JSRM1461. That number covers the 10-32 diameter, 2 inch length, round head slotted, 316 stainless configuration, which is what distinguishes it from the shorter lengths in the same Metallics screw range.
