Metallics JFM42 – Frequently Asked Questions

1) Will the Metallics JFM42 10-32 screw thread into a standard electrical device box or switch plate?
The JFM42 is a 10-32 machine screw with 32 threads per inch cut to ANSI/ASME B1.1, which is the thread used for device mounting holes in outlet boxes, switch boxes and cover plates. At 5/8 inch long it gives enough engagement for a device yoke or a plaster ring without bottoming out in a shallow tapped hole.
2) Are the Metallics JFM42 screws coarse or fine thread, and will they fit a 10-24 tapped hole?
They are fine thread, UNF, at 32 threads per inch. A 10-24 hole is coarse thread (UNC) and these will not thread into it, even though both are number 10 diameter. Match the screw to the tapped hole: 10-32 for electrical device and plate holes, 10-24 for the coarse applications.
3) Can I use the Metallics JFM42 screws on a Buy American or ARRA funded project?
No. The JFM42 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. On a federally funded job with domestic sourcing requirements you will need a domestically produced 10-32 flat head machine screw instead.
4) Does the flat head on these 10-32 screws sit flush in a countersunk hole?
Yes. It is a flat countersunk head with a slotted drive, measuring 0.333 to 0.362 inch across the head and 0.098 to 0.116 inch in head height, so it seats flush in an 82 degree countersink rather than standing proud like a pan or round head.
5) How many Metallics JFM42 screws come in a jar?
They ship in a jar of 100 pieces, which is the order minimum. The filled jar weighs 0.56 lbs.
6) Do these Metallics machine screws meet a recognized dimensional spec for submittals?
Yes. The screw is made to ASME B18.6.3-1998 for slotted flat head machine screw dimensions, with threads to ANSI/ASME B1.1 and steel to AISI 1006 to 1022. Those are the three numbers to put on a submittal or spec sheet.
7) Does a 10-32 machine screw need a nut, or can it go straight into the hole?
A machine screw has a blunt, fully threaded shank with no point, so it needs a mating tapped hole or a nut. It will not cut its own thread in sheet metal or drywall the way a self tapping or sheet metal screw does. On electrical boxes and plates the 10-32 holes are already tapped, which is where this screw is used most.
