Metallics JFM50 – Frequently Asked Questions

1) Will a 5/16-18 machine screw thread into a standard 5/16-18 tapped hole or coupling nut?
Yes. The Metallics JFM50 is cut to UNC threads at 18 threads per inch to ANSI/ASME B1.1, which is the standard coarse 5/16 series, so it mates with any 5/16-18 tapped hole, nut, or strut channel nut.
2) Do these 5/16-18 flat head screws meet Buy American or ARRA requirements for a public job?
No. The JFM50 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic-content requirements, this part will not qualify.
3) How many screws come in a jar, and can I buy less than a full jar?
The JFM50 ships as a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest quantity. The packed jar weighs 1.74 lbs.
4) Is zinc-plated steel OK for outdoor or damp locations?
The JFM50 is zinc-plated carbon steel, which is a mild corrosion coating meant for dry interior electrical, plumbing, heating and air conditioning work. For wet locations, washdown areas, or exterior exposure, step up to a stainless machine screw of the same 5/16-18 size instead.
5) Is 3/4 inch long enough to get full thread engagement in a 1/8 inch panel?
Yes, with room to spare. The screw is 3/4 in. under the head, and because the flat head countersinks into the material, nearly the full 3/4 in. of UNC thread is available for the nut or tapped hole behind a thin sheet metal panel or enclosure wall.
6) Can I get this flat head slotted machine screw in other lengths or diameters?
Yes. The Metallics FM and FMP series covers other sizes and pack quantities by request; the JFM50 is the 5/16-18 by 3/4 in. configuration in a 100-count jar.
