Metallics JFM200SS – Frequently Asked Questions

1) What size and thread does the Metallics JFM200SS machine screw have?
It's a 3/8-16 screw, 1 inch long, with 16 threads per inch in UNC (coarse) form to ANSI/ASME B1.1. That means it mates with any standard 3/8-16 UNC nut or tapped hole. If the hole in your enclosure or channel is tapped fine thread (3/8-24), this screw will not engage it.
2) Will 18-8 stainless machine screws hold up outdoors or in a wash-down area?
18-8 stainless is the grade used where you need general atmospheric corrosion resistance, and it's the usual choice for food processing machinery and refrigeration equipment, so damp and wash-down duty is what it's made for. It also keeps its strength better than plain steel as operating temperature rises. For constant salt spray or chlorinated exposure, 316 stainless is the step up.
3) Is a machine screw the right fastener here, or do I need a bolt or a self-tapping screw?
A machine screw like the JFM200SS is fully threaded 3/8-16 UNC with a blunt end, so it needs a tapped hole or a nut. It will not cut its own thread in sheet metal, and it's not a wood or concrete fastener. If the mating part isn't tapped, pair it with a 3/8-16 nut, or tap the hole first. For a thick unthreaded clamp-up where you want a grip length with no thread in the shear plane, a hex bolt is the better pick.
4) Are these the same dimensions as any other brand's 3/8-16 x 1 in. flat head slotted screw?
Dimensionally, yes. The screw is made to ASME B18.6.3-1998 with ANSI/ASME B1.1 threads, which is the same spec other manufacturers build inch flat head slotted machine screws to, so head diameter, head height and thread fit interchange with any compliant 3/8-16 x 1 in. flat head slotted screw. Material is 18-8 stainless, so match on grade too if you're mixing fasteners in one assembly to avoid dissimilar metal contact.
5) How are the Metallics JFM200SS screws packaged, and is there a minimum order?
They come in a jar of 100, which is also the order minimum (100 count). The jar weighs 3.39 lbs. Handy for a van or shop drawer if you're setting a lot of 3/8-16 hardware; if you only need a handful for one panel, you're still buying the full jar.
6) I need the same screw in a different length or diameter for the rest of the job. Does Metallics make it?
The FM and FMP series covers other sizes and quantities beyond the 3/8-16 x 1 inch, available by request. If you're standardizing an enclosure or panel build on slotted flat head 18-8 stainless, you can stay in the same series and material across lengths.
