Metallics JRM86M – Frequently Asked Questions

1) Will the Metallics JRM86M machine screw thread into standard electrical box and device mounting holes?
The JRM86M is an 8-32 UNC thread, which is the thread used on device mounting holes in outlet and switch boxes, on plaster rings, and on cover plates. 32 threads per inch, coarse series. The 1 inch length gives you room to pick up a box ear through a plaster ring or a shim stack.
2) How many 8-32 x 1 in. round head combo screws come in a jar, and is there a minimum order?
They ship 1,000 per jar, and 1,000 is the order minimum. Total packed weight is 5.72 lbs. If you only need a handful for one device box, this is a bulk jar, not a small pack.
3) Will a round head screw sit flush, or do I need an oval or flat head instead?
It will not sit flush. A round head stands proud of the surface by 0.107 to 0.12 in., with a head 0.287 to 0.309 in. across. That is fine for mounting devices, straps, and brackets where the head bears on the surface. If you need the head buried in a countersunk hole, you want a flat head machine screw instead; for a partly recessed look, an oval head.
4) Do I need a Phillips or a flat driver for these combo machine screws?
Either. The head is a combination drive, slotted and Phillips, so you can run them with a #2 Phillips bit or a flat blade. The slot is 0.045 to 0.054 in. wide and 0.058 to 0.077 in. deep; the Phillips recess measures 0.165 to 0.178 in. across. That is why electricians keep combo screws on the truck, whatever screwdriver is in your hand will drive them.
5) Are these Metallics JRM screws strong enough for structural or load-bearing fastening?
Carbon steel at 60,000 psi minimum tensile and Rockwell B70 to B100 hardness, made from AISI 1006 to 1022 steel. That is standard low-carbon machine screw strength, appropriate for devices, covers, straps, and light brackets. For a graded structural connection you need a graded bolt, not an unhardened machine screw.
6) Can I use these zinc plated steel screws outdoors or in a wet location?
Zinc plated carbon steel is a dry, indoor-location finish. It handles normal interior humidity but will corrode in wet, washdown, coastal, or buried applications. For exterior or damp locations, specify a stainless machine screw in the same 8-32 x 1 size.
7) Do the Metallics JRM86M screws qualify for a Buy American or ARRA funded project?
Both the ARRA Compliant and Buy American Compliant attributes are flagged C for the JRM86M. Country of origin is listed as multiple. For a federally funded job, cite the part number JRM86M on your submittal so the compliance flag travels with the order.
8) What is the exact part number for the 8-32 x 1 in. round head combo machine screw from Metallics?
JRM86M, in the Metallics JRM round head combo series: 8-32 UNC thread, 1 in. length, round head, slotted/Phillips combo drive, zinc plated steel, silver head, 1,000 per jar. That is the number to put on a purchase order or a counter request.
