Metallics JRM4SLT – Frequently Asked Questions

1) Will an 8-32 x 1/4 in. round head machine screw work for mounting a device or cover plate in an electrical box?
8-32 is the standard thread for switch, receptacle and cover plate mounting in North American electrical boxes, and the Metallics JRM4SLT is an 8-32 screw with 32 threads per inch. The 1/4 inch length is short, so it suits tapped holes and thin plate stack-ups rather than deep box ears with spacers. If you need to pull a device out through drywall or a plaster ring, step up to a longer 8-32 screw.
2) Are these zinc plated steel screws OK for outdoor or damp locations?
The JRM4SLT is steel with a zinc finish. Zinc plating handles indoor and dry interior work well, but it is a sacrificial coating that will eventually corrode in wet, washdown, coastal or chemically aggressive locations. For those, specify a stainless 8-32 machine screw instead.
3) Do the Metallics JRM4SLT screws meet Buy American or ARRA requirements on a public project?
The JRM4SLT carries a compliant flag for both ARRA and Buy American in its product record, while country of origin is listed as China. On a federally funded job where the specification requires domestic melt and manufacture, verify the documentation against your project requirements before submitting.
4) Is a machine screw like this the same as a sheet metal or self-tapping screw?
No. A machine screw has a uniform straight thread, 32 per inch here, and needs a mating tapped hole or a nut. It will not cut its own thread into sheet metal or wood. If you are fastening into an untapped hole, use a self-tapping or sheet metal screw instead; if the hole is already tapped 8-32, this is what you want.
5) How much head sits above the surface on the Metallics JRM4SLT round head screw?
Head height runs 0.107 to 0.12 in., with a head width of 0.287 to 0.309 in. A round head is domed and seats on top of the material, so it does not sit flush. Where you need the screw flush with the plate or panel face, use a flat head in a countersunk hole instead.
6) How are the Metallics JRM4SLT screws packaged and what is the minimum order?
They come in a jar, with an order minimum of 100 count. That makes them a shop or truck stock item rather than a single-piece buy, which is how most MRO and electrical crews want 8-32 hardware.
7) What is the strength rating on these 8-32 machine screws?
60,000 psi minimum tensile, with hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial grade machine screw material, fine for device mounting, enclosure covers, brackets and panel work. It is not a graded structural fastener, so do not substitute it where a drawing calls out a Grade 5 or Grade 8 bolt.
8) What is the exact part number and series for these Metallics round head slotted screws?
Order as Metallics JRM4SLT, part of the JRM series of round head slotted machine screws. The JRM family runs across other diameters and lengths, so match the full suffix when you reorder: JRM4SLT is specifically 8-32 x 1/4 in. in steel zinc.
