Metallics JRM13SLT – Frequently Asked Questions
1) Will a 10-32 round head machine screw work in a standard electrical box or device bracket?
Yes. The Metallics JRM13SLT is a 10-32 machine screw, which is the thread used for device mounting and box ears on standard US electrical boxes, with 32 threads per inch. At 5/16 inch long it's a short screw, so use it where the threaded hole is shallow or where you're only picking up a bracket or cover, not where you need to span a deep stack of plaster rings.
2) How many Metallics JRM13SLT screws come in a jar, and can I buy fewer?
They ship in a jar of 100, and 100 count is the order minimum, so that's the smallest quantity you can take. Metallics notes other sizes and quantities are available by request.
3) Is the zinc finish on these steel machine screws suitable for outdoor or damp locations?
These are zinc plated carbon steel (AISI 1006-1022), which is a dry-location finish. Zinc plating handles indoor humidity and incidental moisture, but for wet locations, exterior boxes, or coastal air you want stainless rather than steel zinc. For interior panel, box, and device work the zinc plating is the normal choice.
4) Why a slotted drive instead of Phillips on these Metallics screws?
The JRM13SLT uses a single slot, 0.050 to 0.060 inch wide and 0.065 to 0.087 inch deep. Electricians still carry a flat blade for terminal and cover work, and slotted lets you drive by hand with controlled torque rather than cam out. If your crew is running impact or cordless drivers all day, a Phillips or combo head screw is the better match. Metallics has offered a full combo line since 1985.
5) Do these screws meet Buy American or ARRA requirements for a government job?
The JRM13SLT is flagged ARRA compliant and Buy American compliant in Metallics' data, with country of origin China. On a federally funded project, verify which standard your contract invokes, because those two flags and the origin need to line up with your spec before the submittal goes in.
6) What is the tensile strength and hardness of the JRM13SLT machine screw?
60,000 psi minimum tensile, with a hardness of Rockwell B70 to B100. That is standard low-carbon steel machine screw strength, fine for mounting devices, covers, brackets, and plates. If you're into a structural or high-torque joint, step up to a grade-rated cap screw instead.
7) How much does a jar of 100 of these machine screws weigh for shipping?
The 100 count jar is listed at 0.47 lbs, in a container measuring 3 inches by 3 inches by 2.15 inches. Light enough to throw several sizes in a van kit without thinking about it.
