Metallics JRM62SLT – Frequently Asked Questions
1) What thread size and length is the Metallics JRM62SLT machine screw?
It's a 5-40 screw, 1 inch long. The 5 is the machine screw gauge and 40 is the threads per inch, so it mates with any 5-40 tapped hole or 5-40 nut. Length is measured as 1 inch under the round head.
2) Is a round head slotted screw the right choice for mounting a device or cover plate, or should I use a flat head?
Round head sits proud of the surface, so use the JRM62SLT where the part has a plain through hole and you want bearing surface on top. If your plate or bracket has a countersunk (chamfered) hole and the head must finish flush, a flat head screw is the one you want instead, not this. Drive is a straight slot, so a flat blade driver.
3) Will these zinc plated steel screws hold up in an outdoor or damp electrical enclosure?
The JRM62SLT is carbon steel with a zinc plating, which is a dry indoor finish. It handles general indoor panel, device and enclosure work fine, but in a wet, washdown or coastal location the plating will eventually give up and you should specify stainless instead.
4) How strong is the Metallics 5-40 round head machine screw?
Rated at 60,000 psi minimum tensile, with a hardness of Rockwell B70 to B100, made from low carbon steel in the AISI 1006 to 1022 range. That's standard commercial grade material for light device, bracket and cover fastening, not a structural or high load joint.
5) Can I use the Metallics JRM62SLT on a Buy American or ARRA funded job?
It is flagged compliant for both ARRA and Buy American in the manufacturer's data, with country of origin listed as China. If your specification requires domestic melt and manufacture rather than the compliance flag, verify against the project's own procurement language before you submit it.
6) Is 1 inch too long for a standard device or box mounting hole?
Often, yes. At 1 inch the 5-40 JRM62SLT is a long screw for its gauge, suited to stacking through a spacer, standoff or thick cover. If you are only picking up a thin tapped ear, a shorter 5-40 will seat better and leave less thread hanging past the nut; Metallics lists other lengths in the same JRM round head slotted line.
7) How are the Metallics JRM 5-40 screws packaged and what is the minimum I can buy?
They come in a jar of 100, and 100 count is the order minimum. The packed jar runs 3 x 3 x 2.15 inches and weighs 0.37 lbs, so it drops straight into a van bin or a service cart drawer.
8) Do these screws come with nuts or washers?
No. The JRM62SLT is the screw only, 100 to a jar. If you are through-bolting rather than threading into a tapped hole, order 5-40 nuts and any washers separately.
