Metallics JRM130SLT – Frequently Asked Questions
1) How many screws come in a jar of Metallics JRM130SLT machine screws?
The JRM130SLT ships 50 pieces to a jar, and 50 count is the order minimum. Jar weight works out to 4.34 lbs for the pack, so plan on that if you're carrying a few up a ladder or stocking a van bin.
2) Will a 3/8-16 x 3 in. round head machine screw thread into a standard 3/8-16 strut nut or tapped channel?
Yes. The JRM130SLT is cut 3/8-16, meaning 3/8 inch nominal diameter at 16 threads per inch, which is the standard UNC coarse pitch for that diameter. It mates with any 3/8-16 tapped hole, channel nut, or hex nut. At 3 inches of length you get plenty of reach for stacking a bracket and washers before the nut.
3) Are these zinc plated steel screws OK for outdoor or damp locations?
Zinc plating over carbon steel gives moderate corrosion resistance, which suits dry interior electrical work, panel and enclosure assembly, and covered locations. For direct weather exposure, wet wells, coastal air, or chemical exposure, go with a stainless machine screw instead. The base material here is low carbon steel per AISI 1006 to 1022 with a zinc finish, not stainless.
4) Do these machine screws meet Buy American or ARRA requirements for a public project?
The JRM130SLT is flagged compliant for both ARRA and Buy American in the product record, with China listed as country of origin. If your contract carries a strict domestic end product clause, submit those two data points to the specifying authority before you install, since compliance programs differ on what they accept.
5) Can I get the same 3/8-16 x 3 in. round head screw in a different quantity or a Phillips drive?
The JRM130SLT is the slotted drive version, sold 50 to a jar. Metallics notes that other sizes and quantities in the round head machine screw line are available by request, so if you need a larger bulk count or a different length in the same JRM family, ask for it rather than assuming the jar is the only option. For a Phillips or combo head you'd be looking at a different Metallics catalog number.
