Metallics JRM123SLT – Frequently Asked Questions

1) What thread size and length are the Metallics JRM123SLT machine screws?
The JRM123SLT is a 3/8-16 x 2-1/2 inch round head slotted machine screw. That's 16 threads per inch on a 3/8 inch diameter body, so it mates with any 3/8-16 tapped hole or nut. The 2-1/2 inch length is measured under the round head, which is the standard measuring point for a round head machine screw.
2) Are these zinc machine screws strong enough for a structural bolted connection?
No. The JRM123SLT is a low carbon steel machine screw made from AISI 1006 to 1022 material with a 60,000 psi minimum tensile strength and Rockwell B70 to B100 hardness. That is general purpose fastener grade, not a graded structural bolt. For load bearing steel connections use an SAE Grade 5 or Grade 8 hex bolt instead; this screw is for mounting devices, enclosures, boxes and panels.
3) Will a 3/8-16 x 2-1/2 inch machine screw work for mounting into a threaded electrical enclosure or strut nut?
Yes, as long as the tapped hole or nut is 3/8-16. Machine screws are made for threaded holes and nuts, not for driving into sheet metal or wood, and the JRM123SLT has a full 3/8-16 thread with 16 TPI. At 2-1/2 inches long it gives you room to stack a mounting bracket, washers, and still get full thread engagement on the nut. If your enclosure hole is unthreaded, pair it with a 3/8-16 nut.
4) How are the Metallics JRM123SLT screws packaged and what is the minimum I can buy?
They ship in a jar of 100 pieces, and 100 count is the order minimum. So the smallest buy is one jar, not a single screw. The packed jar weighs 7.54 lbs.
5) Do these screws meet Buy American and ARRA requirements for a public project?
The JRM123SLT carries a C designation for both ARRA Compliant and Buy American Compliant in Metallics' data, with country of origin listed as China. On federally funded work, verify which clause your contract invokes, since the two programs treat fasteners differently.
6) Is the JRM123SLT available in other sizes or a different quantity?
The JRM round head slotted machine screw line runs other diameters, lengths and pack quantities, and Metallics makes those available by request. The JRM123SLT specifically is the 3/8-16 x 2-1/2 inch zinc plated steel version in a 100 piece jar.
