Metallics JRM115SLT – Frequently Asked Questions

1) What thread size and length is the Metallics JRM115SLT machine screw?
It's a 5/16-18 machine screw, 2 inches long, with 18 threads per inch. That's the coarse (UNC) pitch for 5/16 diameter, so it mates with standard 5/16-18 nuts and tapped holes. Thread is cut the full machine-screw style, not a tapping thread, so the hole has to be tapped or you need a nut on the back side.
2) Will a round head slotted screw sit flush in a countersunk hole?
No. The JRM115SLT has a round head that stands proud of the surface, measuring 0.557 to 0.59 in. across and 0.198 to 0.216 in. high. If your part is countersunk for a flush finish, you need a flat head screw instead. Round head works where you have a plain drilled hole and want bearing surface against the material.
3) How strong are these screws, and can I use them for a structural connection?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70-B100, which is ordinary low-carbon machine screw material (AISI 1006 to 1022). That's fine for mounting devices, enclosures, brackets, and trim. It is not a graded structural fastener, so if your drawing calls out a grade or a bolt spec, use a graded bolt rather than this screw.
4) Can I use these on a Buy American or ARRA-funded job?
No. The JRM115SLT is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For federally funded work with domestic-content requirements, you'll need a domestically sourced fastener.
5) Is the zinc plating on these Metallics screws good enough for outdoor or damp locations?
These are carbon steel with a zinc finish, which is a dry-location plating. It handles indoor panel work, device mounting, and enclosure interiors fine, but in exterior, wash-down, or coastal use the plating will eventually give up and rust. For wet or corrosive spots, specify a stainless machine screw in the same 5/16-18 x 2 in. size.
6) Do I have to buy a full jar of these, or can I order a few?
They ship as a jar with a 100-count minimum, so the smallest order is 100 pieces of JRM115SLT. Metallics notes other sizes and quantities are available by request if 5/16-18 x 2 in. isn't the length you need.
