Metallics JFMP90 – Frequently Asked Questions
1) Will a Metallics JFMP90 8-32 machine screw thread into a standard electrical box or device mounting hole?
Yes. The JFMP90 is an 8-32 machine screw, 32 threads per inch, UNC, cut to ANSI/ASME B1.1. That is the same thread used for device mounting holes in outlet boxes, switch boxes, and plaster rings, so it threads straight into existing box ears and mounting straps.
2) Do these screws qualify for a Buy American or ARRA funded project?
No. The JFMP90 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your government, school, or federally funded job carries a domestic sourcing requirement, this fastener will not satisfy it.
3) What screwdriver or bit do I need for the Metallics JFMP90?
A #2 Phillips. The head is a flat Phillips with a recess 0.182 inch in diameter and 0.11 inch deep, which is the standard #2 pocket. A #1 bit will cam out of it and a #3 won't seat.
4) Will this flat head screw sit flush, or will it stand proud of the plate?
Flush, provided the hole is countersunk. The flat head on the JFMP90 measures 0.285 to 0.312 inch across with a head height of 0.084 to 0.1 inch, so it seats down into a countersunk or chamfered hole and finishes level with the surface. On a plain drilled hole with no countersink, the head sits on top.
5) How does the Metallics JFMP90 come packaged and what is the minimum I can buy?
It ships in a jar of 100. The order minimum is 100 count, so this is a bulk service-truck or MRO-shelf item rather than a single-piece pick.
6) Can these zinc machine screws be used outdoors or in a damp location?
Keep them dry. The JFMP90 is low carbon steel per AISI 1006-1022 with a zinc finish, which handles indoor and concealed-box use but is not a corrosion-resistant fastener for wet, coastal, or washdown environments. For those, specify a stainless machine screw in the same 8-32 x 2-1/2 size.
7) What load will an 8-32 x 2-1/2 steel zinc machine screw hold?
Rated at 850 lb minimum tensile, with hardness of Rockwell B70 to B100. That is a general purpose carbon steel fastener for device mounting, plate mounting, and light fixture hardware, not a structural or high-strength grade bolt substitute.
8) Does the Metallics JFMP90 meet a recognized dimensional spec for submittals?
It is manufactured to ASME B18.6.3-1998 for head and screw dimensions and ANSI/ASME B1.1 for the thread form. Gaging diameter is 0.267 with protrusion 0.023 to 0.039 above gage, which is the figure a QC inspector checks a flat head against.
9) I need a different length or thread in the same screw. Is the Metallics FM/FMP line offered in other sizes?
Yes, the FM and FMP series covers other sizes and pack quantities by request. The JFMP90 is the 8-32 x 2-1/2 inch flat head Phillips in zinc plated steel, so if you need a shorter length for standard-depth boxes or a round or oval head, ask for the matching FM/FMP part rather than substituting a different thread pitch.
