Metallics JFMP127SS – Frequently Asked Questions

1) Will a 10-24 x 3 inch flat head Phillips machine screw thread into a standard device box or mud ring?
The Metallics JFMP127SS is a 10-24 UNC thread, 24 threads per inch, cut to ANSI/ASME B1.1. That is the same thread used on standard electrical device and fixture mounting holes, so it mates with 10-24 tapped holes in boxes, mud rings and fixture straps. The 3 inch length is the long one, meant for reaching through deep plaster rings, extension rings or thick wall build-up rather than a flush box.
2) Can I use a machine screw like this in drywall or wood, or does it need a tapped hole?
Machine screws need a mating thread. The JFMP127SS has a 10-24 UNC machine thread with a blunt end, so it goes into a tapped hole, a threaded insert, or a nut. It will not cut its own thread in wood, drywall or sheet metal. For those substrates use a wood screw, a self-drilling sheet metal screw, or install a 10-24 anchor or rivet nut first.
3) Will the flat head sit flush in a countersunk hole, and how much room does the head take?
Yes, it is a flat countersunk head, so it seats flush in an 82 degree countersink. Head width runs 0.333 to 0.362 inch and head height 0.098 to 0.116 inch, dimensioned to ASME B18.6.3-1998. If your plate or bracket is not countersunk, the head will stand roughly a tenth of an inch proud; use a round or pan head instead where a raised head is acceptable.
4) Is 18-8 stainless the right choice for damp, outdoor or washdown locations?
18-8 stainless handles general atmospheric corrosion, which covers damp interiors, food processing equipment and refrigeration gear, and it holds strength better than plain steel as operating temperature rises. It is not a marine-grade alloy, so for constant salt spray or submerged service you want 316 rather than 18-8. For a zinc-plated steel screw in a wet mechanical room, this is the upgrade.
5) Do these stainless machine screws meet Buy American or ARRA requirements on a public project?
The JFMP127SS carries a compliance flag for both Buy American and ARRA, with country of origin listed as China. On federally funded work, submit those flags against your project's specific domestic-content clause, because the threshold varies by funding source.
6) What size Phillips driver do I need for these 10-24 stainless machine screws?
A #2 Phillips. The recess on the JFMP127SS measures 0.198 inch diameter and 0.124 inch deep, which is the standard #2 geometry. Run a driver bit in good condition if you are power-driving, since 18-8 stainless is softer than hardened steel and the recess will cam out and round before the screw snaps.
7) How are these Metallics 10-24 x 3 in. screws packaged, and is there a minimum order?
They ship in a jar of 100, which is the order minimum (100 count). Shipping weight on the jar is 2.01 lbs. Handy if you are stocking a van or a maintenance crib rather than buying loose pieces.
