Metallics JRMB103 – Frequently Asked Questions

1) Will the Metallics JRMB103 10-32 screw thread into a standard electrical box or device yoke?
Yes. The JRMB103 is a 10-32 machine screw with 32 threads per inch cut to ANSI/ASME B1.1, which is the thread 10-32 tapped holes in outlet boxes, device straps, and cover plates use. At 1/4 inch long it is short, so it suits picking up a thin cover or strap against a tapped boss rather than reaching through stacked material.
2) Why choose a brass 10-32 machine screw instead of steel or stainless?
Brass is the material on the JRMB103, and it is the usual pick for electrical grounding and bonding work because it stays conductive and does not rust in damp or outdoor enclosures. For high-strength structural pulls, a steel or stainless screw carries more load; brass is the softer metal of the three, so do not over-torque it in a tapped hole.
3) How big is the round head on this 10-32 slotted screw, and will it sit under a device plate?
Head width runs 0.334 to 0.359 in. and head height 0.123 to 0.137 in. on the JRMB103. That is a domed round head that sits above the surface, not flush, so it needs clearance. If you need the head buried in a countersink, a flat head screw is the right call instead.
4) Is the JRMB103 sold individually or by the jar?
It ships as a 100 count jar. The order minimum is 100 CT and the pack type is a jar, so this is a bulk stocking item for a truck or an MRO shelf rather than a single loose screw.
5) Does this Metallics machine screw meet Buy American and ARRA requirements for a public project?
The JRMB103 is flagged compliant for both Buy American and ARRA in the manufacturer's data, with country of origin listed as China. Institutional and government buyers working to a specific domestic-content clause should check that clause against those two flags, since they are not interchangeable with every agency's rule.
6) What dimensional standard do these round head machine screws conform to?
Head and thread geometry on the JRMB103 is built to ASME B18.6.3, the standard for inch-series machine screws, with threads to ANSI/ASME B1.1. That means head and thread dimensions interchange with any other B18.6.3 round head 10-32 screw from another maker.
7) Can I get this 10-32 brass round head screw in a longer length or a different jar count?
Metallics builds the JRMB series in other sizes and quantities by request. The JRMB103 itself is fixed at 10-32 x 1/4 in., so if your tapped hole or stack-up needs more thread engagement, ask for the longer length in the same series rather than forcing this one.
