Metallics JFM127 – Frequently Asked Questions

1) Does the flat head on this 10-24 x 3 in. screw sit flush in a countersunk hole?
It does, provided the countersink matches. The head measures 0.333 to 0.362 in. across with a head height of 0.098 to 0.116 in., built to ASME B18.6.3-1998, so it seats flush in a standard 82 degree countersink for a #10 flat head screw. If your hole is not countersunk the head will stand proud by roughly a tenth of an inch.
2) Will these screws pass a Buy American or ARRA requirement on a federal job?
No. The JFM127 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a federally funded project with domestic sourcing language you need a domestically produced 10-24 machine screw instead.
3) What screwdriver do I need for the Metallics JFM127 machine screws?
A flat blade driver. These are slotted drive, with a slot 0.05 to 0.06 in. wide and 0.034 to 0.053 in. deep. Pick a cabinet-tip blade that fills the slot width to avoid camming out; no Phillips or square bit will work on them.
4) How many 10-24 x 3 in. flat head screws come in a jar, and can I buy just a few?
They ship in a jar of 100, which is also the order minimum. There is no loose or small-count break on the JFM127, so a single order is a full 100-piece jar weighing 1.96 lbs.
5) Are zinc plated steel machine screws suitable for outdoor or damp locations?
Zinc plating on carbon steel is a mild corrosion coating meant for dry interior service. The JFM127 is zinc finished steel made from AISI 1006 to 1022 carbon steel, so for wet locations, exterior panels, or corrosive atmospheres you want a stainless machine screw of the same 10-24 x 3 in. size instead.
6) How much load will a 10-24 x 3 in. steel machine screw take in tension?
1050 lb minimum tensile, with the steel running Rockwell B70 to B100 for hardness. That is a carbon steel commercial machine screw rating, fine for mounting devices, plates, straps, and light equipment. It is not a structural fastener and carries no SAE grade marking.
7) Is a 3 inch machine screw too long for mounting a device in a standard box?
For a flush device in a standard box, yes, it is far longer than needed. The 3 inch length on the JFM127 is for reaching through built-out surfaces, thick finishes, spacers, or stacked extension rings where a short 1/2 inch device screw cannot bottom in the tapped hole. For normal device mounting, order a shorter 10-24 flat head in the same FM and FMP series.
8) What trades and applications are these Metallics flat head slotted screws intended for?
Metallics lists them for the electrical, plumbing, and heating and air conditioning industries. In practice that is general MRO assembly work: securing covers, plates, brackets, straps, and panels into tapped 10-24 holes. The zinc yellow finish is also common in electronics assembly.
