Metallics JRM54SLT – Frequently Asked Questions

1) What thread size and length are the Metallics JRM54SLT machine screws?
They run 1/2-13 by 3/4 inch long: a 1/2 inch nominal diameter with 13 threads per inch, which is the standard UNC coarse pitch for that diameter. The short 3/4 inch length suits bolting through thin steel channel, boxes, or bracket flanges where you only need a nut or tapped hole on the back side.
2) Will a standard 1/2 inch nut or a 1/2-13 tapped hole take these screws?
Yes. The JRM54SLT is cut 1/2-13, the common coarse thread for 1/2 inch fasteners, so it mates with any standard 1/2-13 nut, strut nut, or tapped hole. It will not thread into a 1/2-20 fine-thread hole.
3) How strong are these Metallics round head machine screws?
Minimum tensile strength is 60,000 psi, with hardness in the Rockwell B70 to B100 range. The steel is made to AISI 1006 to 1022, so this is low-carbon steel fastener stock, fine for general electrical and MRO mounting work rather than high-strength structural bolting where a Grade 5 or Grade 8 bolt is called out on the drawing.
4) Can these zinc plated screws be used outdoors or in damp locations?
The JRM54SLT is low-carbon steel with a zinc finish, which handles indoor and dry or occasionally damp conditions. Zinc plating is a sacrificial coating, not a marine-grade one, so for wet exteriors, wash-down areas, or coastal sites use a stainless machine screw instead.
5) Is a slotted round head screw the right choice, or should I use a Phillips or combo drive?
The JRM54SLT uses a slotted drive with a round head. Slotted is the traditional choice for electrical device and cover work because it drives with a flat blade screwdriver you already have on the belt, but it cams out easily under power tools, so hand-drive it. If you are running screws with a drill, pick a Phillips or combination drive version instead. Metallics offers combination drive machine screws across its line.
6) How do these Metallics machine screws come packaged, and what is the minimum order?
They ship 100 count in a jar, and 100 is the order minimum, so the smallest purchase is one jar of 100 screws. That jar of 1/2-13 by 3/4 inch screws weighs 6.36 lbs. Other sizes and quantities can be requested from Metallics.
7) Do these screws meet Buy American or ARRA requirements for a public project?
The record flags the JRM54SLT as compliant for both ARRA and Buy American, while country of origin is listed as China. On a federally funded job where domestic melt and manufacture is a hard spec line, verify against the specific provision your contract cites before committing the material.
8) What is the part number to reorder these 1/2-13 round head slotted screws?
Order Metallics part number JRM54SLT, from the JRM series of round head slotted machine screws. One model number covers the 1/2-13 by 3/4 inch steel zinc configuration, so there is no finish or length option to specify.
