Metallics JFM85SS – Frequently Asked Questions
1) Will an 8-32 x 3/4 in. machine screw thread into standard electrical device and box tapped holes?
Yes. The Metallics JFM85SS is an 8-32 UNC thread, 32 threads per inch, cut to ANSI/ASME B1.1. That is the same thread used on receptacle and switch mounting holes and most outlet box device ears, so it will run into standard tapped device hardware. At 3/4 in. long it gives extra reach where a plaster ring or box extension sets the device back from the box.
2) Do these stainless machine screws meet Buy American or ARRA requirements for a public job?
No. The JFM85SS 18-8 stainless machine screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing language in the specification, these will not satisfy it.
3) Are 18-8 stainless machine screws the right choice for outdoor or wash-down equipment?
That is exactly what 18-8 stainless is for. The JFM85SS is 18-8 stainless steel, used where general atmospheric corrosion resistance matters, and it is a common pick for food processing machinery and refrigeration equipment. It also holds strength better than plain steel as operating temperature climbs. For continuous salt spray or chemical exposure, 18-8 is still a general-purpose austenitic grade, not a marine-specific one.
4) How much load will an 8-32 18-8 stainless machine screw take?
Rated at 850 lb minimum tensile, with a hardness of Rockwell B85-B95. Worth knowing that there is no national performance standard for stainless machine screws, so those figures are published as a guide rather than a certified grade marking. If your drawing calls out a graded fastener with a defined proof load, a stainless machine screw is not the part that satisfies it.
5) Is the JFM85SS a machine screw or a self-tapping screw?
A machine screw, part of the Metallics FM and FMP series. It has a uniform 8-32 UNC thread with a blunt end and needs an existing tapped hole or a nut to thread into. It will not cut its own threads in sheet metal. For electrical, plumbing, and HVAC work it is the screw used into pre-tapped device holes, boxes, enclosures, and panel hardware.
6) How are these Metallics 8-32 flat head screws packaged, and is there a minimum order?
They come in a jar, with a minimum of 100 pieces per jar. Jar weight is listed at 0.45 lbs. That packaging suits a van stock or shop bin rather than a single-fix purchase, so if you only need a handful for one device plate you are still buying the full jar.
