Metallics JRM142 – Frequently Asked Questions

1) Does the Metallics JRM142 machine screw qualify for a Buy American or ARRA funded project?
No. This screw is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If you are on a federally funded job with domestic sourcing requirements, you will need a domestically produced 6-32 instead.
2) Do I need a Phillips or a slotted screwdriver for Metallics combo drive screws?
Either one works. The JRM142 round head carries a combination slotted/Phillips recess, so you can drive it with a flat blade or a #2 Phillips, whichever is already in your pouch. The Phillips recess runs 0.149 to 0.162 inch diameter with 0.056 to 0.084 inch depth, and the slot is 0.039 to 0.048 inch wide by 0.051 to 0.068 inch deep. That matters in a panel where you are working one-handed and do not want to swap bits.
3) How much clearance does the round head need around the hole?
The head measures 0.24 to 0.26 inch across and stands 0.091 to 0.103 inch proud of the surface. So budget roughly a quarter inch of flat bearing area around the hole and about a tenth of an inch of head projection. A round head sits on top of the material rather than sinking in, so it will not work where you need a flush face, use a flat head countersunk screw for that.
4) How many screws come in a jar of Metallics JRM142?
100 screws per jar, and the jar is the minimum order unit. Total weight of the jar is 1.02 lbs. For MRO stockrooms that is a sensible bin quantity for a long 6-32, which usually gets pulled a few at a time rather than by the box.
5) Is a zinc plated steel machine screw okay for outdoor or damp locations?
Zinc finish over steel handles indoor panels, control cabinets, HVAC equipment and normal jobsite humidity. It is a sacrificial plating, not stainless, so for standing moisture, coastal air, or wet-location enclosures you want a stainless 6-32 instead. Metallics lists this one for electrical, plumbing, and heating and air conditioning work, which is where it belongs.
6) What is a 3 inch long 6-32 screw actually used for?
Deep reach. Common uses are running a device or component through a thick stack in a panel, pulling a fixture body back through insulation or a mud ring build-out, and reaching a tapped boss at the back of an enclosure. Anywhere a standard length 6-32 bottoms out before it engages, this is the one you reach for. Excess length can be cut off after the nut if needed since these are plain machine threads.
