Metallics JSRM80 – Frequently Asked Questions
1) Will a 10-32 x 1/4 in. machine screw thread into a standard electrical box or device yoke?
Yes. 10-32 is the standard thread used for device mounting holes and ground screws in steel outlet and switch boxes, and the JSRM80 is cut 32 threads per inch to match. At 1/4 inch long it is short, so it suits tapped holes where only a few threads engage, not through-bolting thicker assemblies.
2) Are these Metallics round head machine screws stainless, and will they hold up outdoors or in damp locations?
They are 18-8 stainless, the common austenitic grade used where plated steel would rust. That makes them a reasonable pick for damp, wet, or coastal exposure on electrical enclosures and fixture hardware. Hardness runs Rockwell B85 to B95.
3) Can I use the Metallics JSRM80 on a federally funded or Buy American job?
No. The JSRM80 is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. For a project with domestic sourcing requirements you'll need a domestically manufactured 10-32 stainless screw instead.
4) How much tensile strength do these 18-8 stainless machine screws have?
The JSRM80 is rated at 80,000 psi minimum tensile. Keep in mind that stainless machine screw strength figures are approximations, since there is no single performance standard for stainless machine screws, so don't treat them as a substitute for a graded steel fastener in a structural application.
5) How big is the round head on the JSRM80, and will it clear a recessed device hole?
Head width measures 0.334 to 0.359 in. and head height 0.123 to 0.137 in. That domed profile sits above the surface rather than flush, so if your plate or bracket is countersunk for a flat head, this isn't the screw for it.
6) What screwdriver do I need for these Metallics machine screws?
A flat blade. The drive is a single slot, 0.05 to 0.06 in. wide and 0.065 to 0.087 in. deep, so a cabinet tip flat driver seats properly. No Phillips or square drive on this one, which matters if you're running a power driver and expected a recess.
7) Do these come loose by the piece or in a bulk pack?
They ship in a jar, with a 100 count order minimum. So the smallest buy is 100 screws, which is how most shops stock a common 10-32 size for service trucks and MRO bins.
8) Is a 10-32 machine screw the same thing as a sheet metal or self-tapping screw?
No. A machine screw like this has a uniform straight machine thread meant to go into a pre-tapped hole or a nut, with no point to cut its own thread. If you're fastening into unthreaded sheet steel you want a self-drilling or sheet metal screw, not the SRM series.
9) I need a longer 10-32 stainless screw than 1/4 inch. Is that available?
The JSRM80 itself is fixed at 1/4 in. long, but other lengths and quantities in the SRM stainless machine screw line can be had by request. Specify the length you need along with the 10-32 thread and slotted round head when you order.
10) What dimensional standard are these screw threads made to?
The SRM series machine screws are built to SAE material standard, with 32 threads per inch on the 10-32 size. That is the standard unified fine thread for a #10 screw, so it mates with any standard 10-32 tapped hole or nut.
