Metallics JRM130 – Frequently Asked Questions

1) What thread size and length is the Metallics JRM130 machine screw?
The JRM130 is a 3/8-16 machine screw, 3 inches long, with 16 threads per inch. That's the coarse 3/8 machine screw thread, so it mates with a 3/8-16 tapped hole or a 3/8-16 nut. Head is a round head in steel with zinc plating.
2) Can I drive these 3/8-16 combo screws with a Phillips bit, or do I need a flat blade?
Either one. The JRM130 head is a combo drive, slotted and Phillips in the same head, so a flat blade or a Phillips works. For the Phillips side use a #4 driver. The slot runs 0.081 to 0.094 inch wide and 0.117 to 0.155 inch deep, so a wide heavy-duty cabinet blade seats properly rather than a small electrician's screwdriver.
3) Are these sold individually or do I have to buy a full jar?
The JRM130 ships in a jar with a 50 each minimum, so the buying unit is 50 screws. Metallics notes other sizes and quantities are available by request.
4) Do these Metallics screws meet Buy American or ARRA requirements for a public project?
No. The JRM130 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a federally funded job with domestic sourcing requirements, this part will not qualify.
5) How much does the round head stand up off the surface, and how wide is it?
Head height on the JRM130 is 0.237 to 0.256 inch and head width is 0.67 to 0.708 inch. That's a domed profile that sits proud of the surface, so it is not a flush or countersunk screw. If you need the head below the surface, you want a flat head machine screw instead.
6) How strong are these screws, and are they hardened?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70 to B100. The steel is AISI 1006 through 1022, a low carbon range, so these are general purpose fasteners for electrical and mechanical mounting, not a substitute for a grade 5 or grade 8 bolt in a structural or high load joint.
7) What are the Phillips recess dimensions on the JRM130 so I can set up a production driver?
Phillips recess diameter is 0.374 to 0.387 inch, recess depth 0.202 to 0.228 inch, recess width 0.064 inch, and recess penetration gaging depth 0.182 to 0.208 inch. Pair that with a #4 Phillips bit for a correct fit and minimal cam-out on repetitive driving.
