Metallics JRM41SLT – Frequently Asked Questions
1) How are these sold, 100 count or individually?
The JRM41SLT ships as a 100 count jar, and 100 is the order minimum. So one unit on the order gets you a jar of 100 screws, not a single screw. The jar weighs 0.53 lbs.
2) Can I use these to replace a missing green ground screw in a steel box?
Thread-wise yes, 10-24 is the thread tapped into the grounding boss of most steel boxes, and the 5/8 inch length and slotted round head drive the same way. The difference is colour and marking: a dedicated ground screw is green so an inspector can identify it at a glance. For grounding terminations use a green 10-24 ground screw and keep the JRM41SLT zinc screws for general mounting.
3) How strong are these steel zinc machine screws, and are they hard enough for repeated service?
Tensile strength is 60,000 psi minimum, with hardness at Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial-grade machine screw strength: fine for mounting devices, covers, brackets, and enclosure hardware. It is not a high-strength structural fastener, so do not substitute it where a graded bolt is specified on a drawing.
4) Are zinc plated steel machine screws OK outdoors or in a damp location?
Zinc plating over steel is a mild corrosion barrier intended for dry indoor use, which is what the JRM41SLT carries. For wet, washdown, coastal, or buried work, specify stainless machine screws in the same 10-24 x 5/8 size instead, since the zinc will eventually rust through.
5) Do these Metallics machine screws meet Buy American or ARRA requirements on a public project?
Metallics flags the JRM41SLT as compliant for both ARRA and Buy American, while the country of origin is listed as China. If your contract language requires domestic melt and manufacture rather than the compliance flag, get the certification in writing before you submit it.
