Metallics JFM100SS – Frequently Asked Questions

1) Will the Metallics JFM100SS machine screw thread into a 1/4-20 tapped hole or nut?
Yes. The JFM100SS is a 1/4-20 UNC screw, 20 threads per inch, cut to ANSI/ASME B1.1, so it mates with any standard 1/4-20 tapped hole, nut, or strut channel nut. Shank length under the head is 3/4 inch, so your grip plus nut engagement has to fall inside that.
2) Will a 1/4-20 flat head screw sit flush in my countersunk hole?
It will if the countersink matches an 82 degree flat head of this size. Head width on the JFM100SS runs 0.442 to 0.477 in. and head height 0.131 to 0.153 in., per ASME B18.6.3-1998 flat head geometry. If your plate is drilled straight through with no chamfer, the head will stand proud and you want a pan or round head instead.
3) Are the Metallics JFM100SS screws Buy American or ARRA compliant for a government job?
No. The JFM100SS is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project has domestic-sourcing requirements, this is not the fastener to submit.
4) Is 18-8 stainless the right choice for outdoor or wash-down equipment?
That is what it is for. 18-8 stainless machine screws are used where general atmospheric corrosion resistance is needed, including food processing machinery and refrigeration equipment, and they hold strength better than plain steel at elevated operating temperatures. For salt spray or chlorinated environments, 316 stainless is the step up.
5) How many Metallics JFM100SS screws come in a jar, and can I buy just a few?
These ship 100 to a jar, and the jar is the order minimum, so it is a full 100-count package rather than a loose count. The packaged jar weighs 1.08 lbs.
6) Can I use these stainless machine screws for mounting electrical boxes and HVAC panels?
Yes, the field application for these 1/4-20 flat head stainless screws is the electrical, plumbing, heating and air conditioning trades. Typical use is fastening into pre-tapped or nutted holes in boxes, enclosures, straps, and panels. They are machine screws, not self-tappers, so the hole has to be threaded or carry a nut.
