Metallics JRM144SLT – Frequently Asked Questions

1) Is the head on the Metallics JRM144SLT low enough to sit under a cover plate?
The round head measures 0.24 to 0.26 in. across with a head height of 0.091 to 0.103 in. That is a domed head, not a flat or oval countersink head, so it sits on top of the surface rather than flush in a chamfered hole. If you need the screw to disappear into a countersunk plate hole, a round head is the wrong profile.
2) How are these Metallics machine screws packaged and what is the minimum I have to buy?
They ship in a jar, with an order minimum of 100 count. So this is a bulk shop quantity rather than a single fastener, which is how most electrical contractors stock long device screws on the truck.
3) Are zinc plated steel machine screws acceptable for damp or outdoor electrical work?
Zinc plated carbon steel is a dry interior finish. The JRM144SLT is steel with a zinc finish, which handles normal indoor box and device work but will corrode in wet, exterior, or washdown locations. For those, specify a stainless machine screw in the same 6-32 x 4 in. size instead.
4) What is the strength rating on these Metallics 6-32 screws, and can I torque them down hard?
Minimum tensile strength is 60,000 psi, with a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard low carbon machine screw material: fine for mounting devices, plates, straps and enclosure components, not a substitute for a graded cap screw in a structural or high-torque joint.
5) Do these screws meet Buy American or ARRA requirements on a federal or institutional job?
Both the ARRA and Buy American compliance flags on the JRM144SLT read C, with country of origin China. Procurement officers writing domestic-content clauses should treat the origin as the governing fact and confirm it against the clause in their contract before submitting.
6) How much does a 100 count jar of these 6-32 x 4 in. screws weigh?
About 1.41 lbs for the packaged jar. Useful if you are building a parts order to a weight limit or stocking a van shelf with several sizes.
