Metallics JRM37SLT – Frequently Asked Questions

1) Will a Metallics JRM37SLT machine screw thread into a standard electrical box or device yoke?
Yes. The JRM37SLT is a 12-24 machine screw, 24 threads per inch, which is the standard thread used for device mounting and ground screw holes in steel outlet and switch boxes. At 3/4 inch long it gives enough engagement for mounting straps and brackets without bottoming out in a shallow box.
2) Do Metallics JRM37SLT screws meet Buy American or ARRA requirements for a federal job?
No. The JRM37SLT is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing requirements, you will need a domestically produced fastener instead.
3) How many 12-24 x 3/4 round head slotted screws come in a pack, and how are they packaged?
They ship 100 to a jar. The order minimum is 100 count, so a jar is the smallest buy.
4) Is the JRM37SLT screw head going to sit flush, or does it stand proud of the surface?
It stands proud. The round head is a domed, non-countersunk head measuring 0.382 to 0.408 in. across with a head height of 0.139 to 0.153 in., so it bears on top of the material rather than sinking into it. If you need the head below the surface, you want a flat or oval head instead.
5) What driver do I need for Metallics JRM round head machine screws?
A flat blade screwdriver. The drive is a single slot, 0.056 to 0.067 in. wide and 0.073 to 0.096 in. deep, so a standard cabinet tip blade seats properly. There is no Phillips or combo recess on this one, so a bit driver with only cross-tip bits will not turn it.
6) Are these zinc machine screws suitable for outdoor or damp locations?
These are carbon steel with a zinc plated finish, which handles indoor and normally dry locations well. Zinc plating gives sacrificial corrosion protection but it is a thin coating, so for wet, coastal, or wash-down environments a stainless machine screw is the better call.
7) How strong is a Metallics 12-24 steel machine screw?
Minimum tensile strength is 60,000 psi, with a hardness of Rockwell B70 to B100, made from low carbon steel in the AISI 1006 to 1022 range. That is standard low carbon machine screw strength, fine for device mounting, straps, covers, and bracket work, but it is not a graded structural fastener.
8) Can I get the same 12-24 round head slotted screw in a different length or larger quantity?
Yes. Metallics offers other sizes and quantities in the JRM series by request; the JRM37SLT is specifically the 12-24 x 3/4 in. round head slotted version in zinc plated steel.
