Metallics JRM61SLT – Frequently Asked Questions

1) Will a 4-40 machine screw thread into a standard switch or receptacle device yoke?
No. Device mounting yokes on switches and receptacles take 6-32 threads, and the Metallics JRM61SLT is a 4-40 screw with 40 threads per inch. For device and cover plate mounting you need 6-32. The 4-40 size is used for smaller tapped holes, small terminal blocks, and light sheet metal assemblies.
2) We have a Buy American clause on a federally funded job. Does this screw qualify?
The JRM61SLT is flagged Buy American compliant and ARRA compliant in the product record, while the country of origin is listed as China. On a federally funded project, give your compliance officer both of those facts before you submit the submittal package.
3) How many Metallics JRM61SLT screws come in a jar, and can I buy fewer?
They ship 100 to a jar, and 100 count is the order minimum, so the jar is the smallest unit sold.
4) How strong is a 4-40 steel machine screw, and is it hard enough for a tapped metal hole?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial machine screw grade, fine for pulling down covers, brackets, and small devices into tapped holes or nuts. It is not a hardened structural or self-drilling fastener, so do not use it to cut its own thread in hard steel.
5) Is 1 inch too long for the panel I'm fastening?
The JRM61SLT is a full 1 inch of screw length under a round head, which is long for a 4-40. It suits stacked assemblies, standoffs, and thick spacers. Fastening two pieces of thin sheet metal will leave most of the thread hanging out the back, so for that work order a shorter 4-40 in the same JRM round head slotted line.
