Metallics JRM312SLT – Frequently Asked Questions

1) Will a 10-24 machine screw thread into a standard electrical box or device yoke?
Yes. The Metallics JRM312SLT is a 10-24 machine screw, 24 threads per inch, which is the standard thread for device mounting holes in outlet boxes, switch boxes and device straps. At 3-1/2 inches long it is meant for deep-set boxes, extension rings or thick wall build-ups where a stock 1-inch device screw runs out of reach.
2) What head size does this round head slotted machine screw have, and will it sit on a device strap without pulling through?
The round head measures 0.334 to 0.359 inch across with a head height of 0.123 to 0.137 inch. That bearing surface is wider than a 10-24 clearance hole in a device yoke or plaster ring, so it seats on the strap rather than pulling through. The dome profile sits proud, so it is not a flush or countersunk substitute.
3) Are these zinc machine screws rated for outdoor or damp locations?
These are low carbon steel with a zinc finish. Zinc plating handles indoor and dry-location service and gives short-term protection in damp conditions, but it is not a stainless screw. For wet locations, coastal exposure or anywhere the screw sees standing water, go to a 10-24 stainless machine screw instead.
4) How strong are these 10-24 screws? Can I use them for a structural or load-bearing connection?
Minimum tensile strength is 60,000 psi, with hardness of Rockwell B70 to B100, from AISI 1006-1022 low carbon steel. That is standard commercial machine screw grade, fine for mounting devices, covers, straps, plates and light equipment. It is not a graded structural fastener, so do not substitute it for a Grade 5 or Grade 8 bolt in a load-bearing joint.
5) Do these Metallics machine screws meet Buy American or ARRA requirements on a federal job?
Metallics lists the JRM312SLT as ARRA compliant and Buy American compliant. Country of origin is China. On a federally funded project where the spec draws a hard domestic-melt-and-manufacture line, confirm which standard your contract is citing before you submit these.
6) Do I need a nut with these, or do they thread into something?
A machine screw has a straight machine thread, so it needs a tapped hole or a nut. Mounting a device into a box, the 10-24 thread picks up the tapped ear in the box or ring. On a blank plate or equipment panel with a clearance hole, you will need a 10-24 nut, which is not included with the screws.
7) How much does a jar of 100 of these 3-1/2 inch screws weigh for shipping?
The 100-count jar of JRM312SLT screws weighs 2.29 lbs. Useful if you are consolidating a fastener order onto a pallet or figuring out what a van stock refill adds up to.
