Metallics JFMP19SS – Frequently Asked Questions

1) Will a 10-24 x 3/8 in. machine screw thread into standard electrical box and device mounting holes?
The Metallics JFMP19SS is a 10-24 UNC thread screw cut to ANSI/ASME B1.1, with 24 threads per inch, so it mates with any tapped 10-24 hole. That is the thread used on most steel outlet and device box mounting ears and on cover plate bosses. At 3/8 in. long it is short, so it suits a single-thickness bracket or ear; if you are stacking a plaster ring plus a bracket you need a longer screw.
2) Will a flat head machine screw sit flush, and what countersink does it need?
Flat head means it is designed to finish flush in a countersunk or chamfered hole. On the JFMP19SS the head measures 0.333 to 0.362 in. across with a head height of 0.098 to 0.116 in., so the countersink has to accept roughly a 3/8 in. head. In a plain punched hole with no chamfer the head will stand proud by about the head height. The screws are made to ASME B18.6.3-1998 head dimensions, so they interchange with any other B18.6.3 flat head 10-24.
3) What size Phillips driver do I need for these Metallics 10-24 stainless screws?
A #2 Phillips. The recess on the JFMP19SS measures 0.198 in. diameter with a 0.124 in. depth, which is a #2 recess, so a #2 bit seats fully and keeps you from camming out in stainless. Stainless is softer than hardened steel and will chew a recess quickly with an undersized bit.
4) Are these stainless screws suitable for outdoor, washdown, or refrigeration use?
Yes. The JFMP19SS is 18-8 stainless, which is used where general atmospheric corrosion resistance is needed, including food processing machinery and refrigeration equipment. 18-8 also holds its strength better than plain steel at elevated operating temperatures. For heavy salt or chemical exposure, 18-8 is not the same as a 316 grade.
5) Do these screws meet Buy American or ARRA requirements for a public project?
The JFMP19SS carries both an ARRA compliant and a Buy American compliant designation in Metallics' data, with country of origin listed as China. Institutional and government buyers working to a specific domestic-content clause should match the clause wording against those designations, since the two programs are written differently.
6) Is a machine screw the right choice, or should I be using a sheet metal or self-tapping screw?
A machine screw like the JFMP19SS has a uniform 10-24 UNC machine thread with a blunt end, so it needs a tapped hole or a nut on the back side. It will not cut its own thread. If you are fastening into unthreaded sheet steel with no access behind, use a self-tapping or sheet metal screw instead. Where the hole is already tapped 10-24, as on device boxes and equipment chassis, the machine screw is correct.
7) How are these Metallics JFMP19SS screws packaged and what is the minimum order?
They come in a jar of 100 pieces, and 100 count is the order minimum. Packaged weight is 0.38 lbs. For an MRO crib or a service van, the jar keeps the count contained rather than loose in a bin.
8) Can I get this Metallics flat head stainless screw in other lengths or diameters?
The JFMP19SS is the 10-24 x 3/8 in. size in Metallics' FM and FMP flat head machine screw series, and other sizes and quantities in that series are available by request. If you need the same 18-8 stainless flat head Phillips in a longer shank for stacked brackets, ask for the series size you need rather than substituting a different head style.
