Metallics JRM112SLT – Frequently Asked Questions
1) Is a slotted round head screw the right choice, or should I use a combination/Phillips head?
The JRM112SLT has a round head with a slotted drive only, with slot width 0.045 to 0.054 in. and slot depth 0.058 to 0.077 in. Slotted is what most electrical device and cover plate screws use, and it drives fine with a standard flat blade. If your crew runs Phillips or square bits off a driver, a combination head screw is the better pick, since a slot this narrow cams a flat blade out under power driving.
2) Are these zinc plated steel screws OK for outdoor or damp locations?
These are steel with a zinc finish, made from AISI 1006 to 1022 low carbon steel. Zinc plating handles dry interior work and normal box and panel use, but it is a sacrificial coating and will corrode in wet, exterior, or washdown locations. For those, specify a stainless 8-32 round head slotted screw instead.
3) How strong is the JRM112SLT, and can I torque it down hard?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70 to B100. That is standard low carbon steel machine screw strength, fine for mounting devices, plates, brackets, and enclosure hardware. It is not a grade 5 or grade 8 cap screw, so do not substitute it into a structural or high torque joint.
4) Do I have to buy these Metallics screws in bulk, and how do they ship?
The JRM112SLT comes in a jar of 100, with an order minimum of 100 count. That jar weighs 1.17 lbs. Practical for a shop or MRO stockroom running a standing 8-32 bin rather than someone needing two screws.
5) Do these Metallics screws meet Buy American or ARRA requirements on a public project?
The record flags the JRM112SLT as compliant for both ARRA and Buy American, with country of origin China. On a federally funded job where domestic sourcing is enforced, verify against your project's specific clause, since origin and compliance flags are not the same test.
