Metallics JRM32M – Frequently Asked Questions

1) Will a 10-24 x 1/2 in. round head combo machine screw thread into a standard electrical box or device mounting hole?
Yes. The Metallics JRM32M is a 10-24 machine screw, 24 threads per inch, which is the standard thread for outlet box, device and cover plate mounting holes in US electrical work. At 1/2 inch long it suits direct device-to-box fastening rather than deep standoff work.
2) Can I drive these round head combo screws with a Phillips bit, or do I need a slotted screwdriver?
Either one. The JRM32M head is a combo recess, slotted and Phillips in the same head, so a flat blade or a #2 Phillips bit both work. The Phillips recess runs 0.182 to 0.195 inch in diameter with a 0.093 to 0.119 inch depth; the slot is 0.05 to 0.06 inch wide and 0.065 to 0.087 inch deep. That is what lets one driver in the pouch cover the whole job.
3) Do these Metallics screws meet Buy American or ARRA requirements for a government job?
No. The JRM32M is listed as not Buy American compliant and not ARRA compliant, with a multiple-country origin. On federally funded work with domestic sourcing requirements, you will need a domestically produced machine screw.
4) How many Metallics JRM32M screws come in a package?
They ship in a jar with an order minimum of 1,000 pieces. If you need a smaller count or a different length in the same 10-24 combo round head, Metallics states other sizes and quantities are available by request.
5) Are these zinc machine screws suitable for outdoor or damp locations?
These are steel with a zinc finish, which is a dry-location, indoor-duty plating. It handles incidental moisture but it is not a marine or sustained-wet coating. For exterior panels, wet locations or washdown areas, specify a stainless machine screw in the same 10-24 x 1/2 size instead.
6) What is the tensile strength and hardness of the Metallics JRM32M machine screw?
60,000 psi minimum tensile, with a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard low carbon machine screw duty: fine for device, panel, enclosure and cover plate fastening, not a substitute for a graded structural bolt.
7) How much does the round head sit up off the surface?
The JRM32M round head measures 0.334 to 0.359 inch across with a head height of 0.123 to 0.137 inch, so it stands proud of the surface by roughly an eighth of an inch. If you need the fastener flush in a countersunk hole, a flat head machine screw is the right choice instead of this round head.
