Metallics JFMP67SS – Frequently Asked Questions

1) Will a 5/16-18 machine screw thread into my existing 5/16 UNC tapped hole or nut?
Yes. The Metallics JFMP67SS is a 5/16-18 UNC screw, 18 threads per inch, cut to ANSI/ASME B1.1. That is the standard coarse thread for 5/16 inch fasteners, so it mates with any 5/16-18 tapped hole, nut, or insert. It will not thread into a 5/16-24 fine-thread hole.
2) What size Phillips driver bit do I need for these 5/16-18 stainless screws?
A #4 Phillips bit. The recess on the JFMP67SS measures 0.358 in. diameter, 0.205 in. deep, with a 0.061 in. slot width. A #3 bit will cam out and chew the recess on a screw this size, so stock the #4 before you start the run.
3) Can I use these stainless machine screws outdoors or in a washdown area?
18-8 stainless is the right choice for general atmospheric corrosion resistance, which is why these screws get specified in food processing machinery and refrigeration equipment where moisture and cleaning chemicals are routine. 18-8 also holds its strength better than plain steel as operating temperature rises. For marine immersion or heavy chloride exposure, 18-8 is not the top tier of stainless.
4) How are these sold, loose or in a pack?
They come in a jar of 100, which is the order minimum. Full jar weight is 2.91 lbs. Other sizes and quantities can be arranged by request.
5) Will a 1-1/2 inch screw be long enough for my assembly?
On a flat head screw the 1-1/2 in. length is measured including the head, since the head sits flush in the countersink. So your usable grip is the full 1-1/2 in. minus the material you are countersinking into. Add up panel thickness plus the depth of thread engagement you need, and if the total runs past 1-1/2 in. you need a longer screw in the same 5/16-18 thread.
6) Do these screws meet Buy American or ARRA requirements for a government job?
The JFMP67SS carries a C designation for both Buy American and ARRA compliance, with country of origin listed as China. For a federally funded project with strict domestic sourcing language, confirm that designation against your contract's specific clause before you commit the material.
