Metallics JFMP100SS – Frequently Asked Questions

1) What thread does the Metallics JFMP100SS machine screw have, and will it thread into a 1/4-20 tapped hole or standard nut?
It's a 1/4-20 UNC thread, 20 threads per inch, cut to ANSI/ASME B1.1. So it mates with any standard 1/4-20 tapped hole, coupling, or hex nut. Screw length is 3/4 inch under the head.
2) Can I use these on a federally funded or Buy American job?
No. The JFMP100SS is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin. If your spec carries a domestic-content requirement, these won't satisfy it.
3) What size Phillips driver do I need for these 1/4-20 flat head screws?
A #3 Phillips. The recess is 0.276 inch in diameter and 0.16 inch deep, so a #2 bit will cam out and chew the recess under any real torque. Load up a #3 bit before you start the run.
4) Are these stainless screws OK for outdoor, washdown, or refrigeration work?
They're 18-8 stainless, which is the grade used where general atmospheric corrosion resistance matters, including food processing machinery and refrigeration equipment. Stainless also holds strength better than plain steel as operating temperature climbs. For salt spray or chemical immersion service you'd want to step up from 18-8.
5) How many Metallics JFMP100SS screws come in a pack?
They ship 100 to a jar, and 100 is the order minimum. One jar covers a decent panel or device-mounting run without opening a second container mid-job.
6) What trades actually use the Metallics FM/FMP flat head machine screws?
They're stocked for the electrical, plumbing, and HVAC trades. Typical use is fastening device plates, enclosure covers, brackets, and equipment panels into tapped holes where the head has to finish flush. The 3/4 inch length suits thin-to-moderate material stacks where you still get full thread engagement.
7) Will these stainless screws gall when I run them into a stainless nut?
18-8 stainless on 18-8 stainless is prone to thread galling if driven fast or dry, and these are 18-8 throughout. Run them in slowly with a #3 Phillips, or use an anti-seize on the 1/4-20 UNC thread. Against an aluminum or carbon steel tapped hole it isn't a concern.
