Metallics JFM11 – Frequently Asked Questions

1) Will Metallics JFM11 8-32 machine screws thread into a standard electrical box or device yoke?
Yes. The JFM11 is an 8-32 UNC screw cut to the ANSI/ASME B1.1 thread standard with 32 threads per inch, which is the same 8-32 thread used on device yokes, box ears, and cover screws. At 5/16 inch long it is a short screw, so it suits shallow tapped holes rather than deep standoffs.
2) Does the flat head on this 8-32 screw sit flush, and what countersink does it need?
The JFM11 is a flat head, so it seats flush in a countersunk hole. The head measures 0.285 to 0.312 inch across with a head height of 0.084 to 0.1 inch, built to ASME B18.6.3-1998, so any standard 82-degree countersink prepped for a #8 flat head will take it flush.
3) How many Metallics JFM11 screws come in a package?
They ship in a jar of 100. The order minimum is 100 count, so 100 pieces is the smallest quantity you can buy.
4) Is the zinc finish on these 8-32 screws good enough for outdoor or damp locations?
The JFM11 is zinc plated carbon steel (AISI 1006-1022). Zinc plating is a mild indoor corrosion coating, fine for panels, boxes, and dry interior work. For wet locations, washdown areas, or exterior use, specify a stainless machine screw instead.
5) How strong is a Metallics JFM11 8-32 screw in tension?
Rated at 850 lb minimum tensile, with a hardness of Rockwell B70 to B100. That is standard low-carbon machine screw strength, suitable for mounting devices, covers, and plates. It is not a graded structural fastener, so do not substitute it where a Grade 5 or Grade 8 bolt is called out.
6) What is the difference between a machine screw like this and a self-tapping sheet metal screw?
The JFM11 is a machine screw with a uniform 8-32 UNC thread, so it needs a pre-tapped hole or a nut. A sheet metal screw cuts its own thread into unthreaded material. If you are fastening into an existing 8-32 tapped hole in a box, yoke, or enclosure, the machine screw is the correct part; for bare sheet with only a pilot hole, use a tapping screw.
7) Do these Metallics machine screws meet Buy American or ARRA requirements on a public project?
The JFM11 is flagged compliant for both ARRA and Buy American in the manufacturer's product data, with country of origin listed as China. Procurement teams working to a specific Buy America clause should match that flag against the clause their contract cites.
