Metallics JSRM101 – Frequently Asked Questions

1) Will a 12-24 machine screw thread into a standard electrical box or device ring?
Yes. 12-24 is the standard thread used in steel outlet boxes, mud rings and plaster rings, and the Metallics JSRM101 is a 12-24 thread with 24 threads per inch. At 1/2 inch long it is a common replacement for box-mounting and ring-mounting screws.
2) How many Metallics JSRM101 screws come in a jar, and can I buy just a few?
The JSRM101 ships as a jar of 100, and 100 count is the order minimum, so it is sold by the jar rather than by the piece.
3) Will a round head slotted screw sit flush, or does the head stand above the surface?
It stands proud. The round head is domed, measuring 0.139 to 0.153 in. high and 0.382 to 0.408 in. across, so it seats on top of the material rather than sinking in. If you need the head flush with a cover plate or panel face, you want a flat head countersunk screw instead.
4) Are these stainless machine screws OK for outdoor or damp locations?
They are made from 18-8 stainless, an austenitic grade that resists corrosion in wet and washdown areas, so they hold up far better than plated steel screws in exterior boxes, damp basements or coastal work. Hardness runs Rockwell B85-B95.
5) What screwdriver or bit drives these, and can I run them with a drill?
They take a slotted (flat blade) driver. The slot is 0.056 to 0.067 in. wide and 0.073 to 0.096 in. deep, which is a hand-driver job in practice; slotted heads cam out easily under power, so if you are installing hundreds a Phillips or combination head screw is the faster choice.
6) Do these Metallics screws meet Buy American or ARRA requirements on a public job?
The JSRM101 is flagged compliant for both ARRA and Buy American in the manufacturer data, with country of origin listed as China. For a federally funded project, verify which standard your specification cites, because the compliance flag and the origin need to be read together by your submittal reviewer.
7) Is 1/2 inch long enough for mounting a device or cover to a steel box?
For typical device-to-box and cover-to-ring work, 1/2 inch of 12-24 thread engages the tapped hole fully without bottoming out behind the box ear. Where you are stacking spacers, thick gaskets or multiple gangs, step up to a 3/4 or 1 inch 12-24 screw to keep enough thread in the hole.
8) What tensile strength can I count on from an 18-8 stainless machine screw?
80,000 psi minimum is the figure Metallics publishes for these. Worth knowing: stainless machine screw strength values are approximations, since there is no single performance standard for stainless machine screws. For a graded structural strength requirement, specify an alloy steel screw to a stated grade instead.
9) Can I get the same screw in a different length or a larger count for a big job?
Yes, the SRM series covers other sizes and quantities by request beyond the 12-24 x 1/2 in. jar of 100. That matters if you are standardizing a maintenance stock room on one thread and want several lengths of the same 18-8 stainless screw.
