Metallics JFM105 – Frequently Asked Questions

1) What thread does the Metallics JFM105 machine screw use, and will it take a standard 1/4-20 nut?
The JFM105 is a 1/4-20 UNC machine screw, 20 threads per inch, cut to ANSI/ASME B1.1. That means it mates with any standard 1/4-20 coarse nut, tapped hole, or threaded insert. Overall length is 3 inches.
2) Is the Metallics JFM105 Buy American or ARRA compliant for a government job?
No. The JFM105 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.
3) How many 1/4-20 x 3 in. machine screws come in a jar?
They ship in a jar of 100, and 100 is the order minimum, so you buy by the jar rather than the piece.
4) Is a zinc plated steel machine screw okay for outdoor or wet locations?
The JFM105 is zinc plated carbon steel (AISI 1006-1022). Zinc plating is a mild corrosion barrier meant for dry indoor work, so it suits interior electrical, plumbing, and HVAC assemblies. For exterior, damp, or washdown areas, go with a stainless machine screw of the same 1/4-20 x 3 in. size.
5) Is this 1/4-20 x 3 in. screw long enough for my application?
Three inches of total length, measured from under the flat head as flat head screws are, so the full 3 inches goes into the material. Subtract your plate or strap thickness to see how much thread is left for the nut. For thinner stacks a shorter length in the same FM and FMP series keeps the thread engagement correct without excess sticking out.
6) What trades actually use these flat head machine screws?
Metallics lists the JFM105 for electrical, plumbing, and heating and air conditioning work. Typical uses are fastening device plates, box covers, hangers, straps, and equipment panels into tapped holes or through-bolted with a nut. The yellow zinc version of these screws is also common in electronics assembly.
7) What does a full jar of these 1/4-20 x 3 in. screws weigh?
A jar runs 3.38 lbs and the container measures 3.5 in. wide by 3.5 in. long by 5.75 in. high, which matters if you are stocking a van bin or a shop drawer.
