Metallics JFM130 – Frequently Asked Questions

1) Will a 3/8-16 machine screw thread into a standard 3/8 UNC tapped hole or nut?
Yes. The Metallics JFM130 is a 3/8-16 UNC screw, 16 threads per inch, cut to ANSI/ASME B1.1. That is the standard coarse thread for 3/8 inch hardware, so it mates with any 3/8-16 tapped channel, strut nut, or hex nut.
2) How deep do I need to countersink for this flat head screw to sit flush?
The flat head on the JFM130 runs 0.67 to 0.717 in. across the head and 0.2 to 0.23 in. in head height, dimensioned to ASME B18.6.3-1998. Use a standard 82 degree countersink sized for that head diameter and the screw will seat flush with the surface.
3) How strong is this screw, and will it hold in a structural or load-carrying connection?
The JFM130 is rated at 4,650 lb minimum tensile, with hardness of Rockwell B70-B100, made from AISI 1006-1022 steel. That is plenty for electrical, plumbing, and HVAC mounting, panel, and bracket work. It is a commercial machine screw, not a graded structural bolt, so if your drawing calls out an SAE grade or ASTM structural bolt, specify that instead.
4) Do these screws meet Buy American or ARRA requirements for a federal or public project?
No. Model JFM130 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, this screw will not satisfy it and you need a domestically produced fastener.
5) How much material can a 3 inch long machine screw actually clamp?
Fastener length is 3 inches, measured from the bearing surface of the flat head (flat heads are measured overall, so the full 3 inches goes into the hole). Subtract whatever thread engagement your nut or tapped hole needs and the rest is usable grip, so this size suits stacked plates, spacers, and through-bolting thicker assemblies rather than thin sheet work.
6) Is zinc plated steel okay outdoors or in a damp mechanical room?
The finish is zinc plating over steel, which handles indoor and protected locations well, dry electrical rooms, panel interiors, mechanical spaces. Zinc plate is a sacrificial coating, not stainless, so for direct weather exposure, wash-down areas, or corrosive atmospheres go with a stainless machine screw in the same 3/8-16 x 3 size.
7) Are these machine screws sold individually or by the box?
They ship in a jar, with an order minimum of 100 pieces per jar. If you need a different count or a different size in the FM/FMP series, other sizes and quantities are available by request.
8) What is the shipping weight on a jar of these 3/8-16 x 3 in. screws?
A jar comes in at 8.19 lbs, with carton dimensions of 7.25 x 4.5 x 4.5 in. Worth knowing if you are staging several sizes on a cart or spec'ing a stock room shelf.
