Metallics JFM103SS – Frequently Asked Questions

1) Will a 1/4-20 machine screw thread into my existing tapped hole or standard 1/4-20 nut?
Yes. The Metallics JFM103SS is a 1/4-20 UNC thread, 20 threads per inch, made to ANSI/ASME B1.1. That is the standard coarse 1/4 inch machine screw thread, so it mates with any 1/4-20 tapped hole, nut, or strut channel nut cut to the same standard. Overall length is 1-1/2 inches, so you need enough grip plus thread engagement within that.
2) Are these stainless screws OK for outdoor or wet locations, like exterior boxes and wash-down areas?
18-8 stainless is the material, chosen for general atmospheric corrosion resistance, and it is used in food processing machinery and refrigeration equipment where wash-down and moisture are routine. It also holds strength better than plain steel at elevated operating temperatures. For heavy chloride exposure (coastal spray, pool chemistry) 18-8 is not the top tier, but for general exterior electrical and HVAC work it is the usual choice over zinc-plated steel.
3) Can I use these on a Buy American or ARRA-funded job?
No. The JFM103SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded or domestic-content job you will need a domestically sourced fastener instead.
4) How many screws come in a jar of Metallics JFM103SS, and can I buy fewer?
They ship 100 to a jar, and the jar is the order minimum. If you need a different count or a different length in the FM and FMP series, other sizes and quantities are available by request.
5) Do I need a special bit, or will a standard flat-blade screwdriver drive these?
A standard flat-blade driver does it. The slot is 0.064 to 0.075 in. wide and 0.046 to 0.07 in. deep, so a medium cabinet-tip blade that fills the slot width is what you want. Slotted drive does not cam out like Phillips, but it also will not hold a bit on a driver, so these are easier by hand than on a drill.
6) What trades actually use these 1/4-20 stainless machine screws?
They are stocked for electrical, plumbing, heating and air conditioning work: mounting devices and plates to tapped holes, panel and enclosure hardware, strut and bracket assembly, equipment covers. The 1-1/2 inch length suits stacked or gasketed assemblies where a shorter screw will not reach the threads.
7) How much does a jar of 100 of these 1/4-20 x 1-1/2 stainless screws weigh for shipping?
The jar weighs 1.83 lbs, with a package footprint of 3 x 3 x 3.6 inches. Light enough to carry several jars on the van without much thought.
