Metallics JRM72SLT – Frequently Asked Questions

1) What thread does the Metallics JRM72SLT machine screw use, and will it run into a 3/8-16 tapped hole or nut?
The JRM72SLT is a 3/8-16 machine screw, 16 threads per inch, so it threads into any 3/8-16 tapped hole, nut, or strut channel nut. Usable length is 1-1/4 inches under the head, which is what limits how much material you can clamp. Note 3/8-16 is a UNC coarse thread; it will not engage a 3/8-24 fine-thread nut.
2) Are these zinc plated steel screws OK outdoors or in a wet location?
The JRM72SLT is carbon steel with a zinc finish, which is a dry-location and indoor plating. It handles handling and incidental moisture, but in wet, washdown, coastal, or buried applications zinc plated steel corrodes. For those, go to a stainless 18-8 machine screw in the same 3/8-16 x 1-1/4 size.
3) How strong are the Metallics JRM72SLT screws - can I use them on a structural or load-bearing connection?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70 to B100, made from AISI 1006-1022 low carbon steel. That is standard commercial machine screw material, fine for mounting boxes, panels, covers, enclosures, and equipment. It is not a graded structural fastener - if a drawing calls out an SAE Grade 5 or Grade 8 bolt, or an ASTM structural bolt, this screw does not substitute.
4) Is a machine screw like this the right fastener for mounting into sheet metal or drywall?
No. A machine screw such as the 3/8-16 x 1-1/4 JRM72SLT has a straight, blunt-ended machine thread and needs a mating tapped hole or a nut - it will not cut its own thread. For sheet metal use a self-tapping or sheet metal screw; for hollow wall use a toggle or anchor. Machine screws are for pre-tapped equipment holes, channel nuts, and bolted-through assemblies.
5) Do the JRM72SLT screws come loose or in a package, and what is the smallest quantity I can order?
They ship in a jar, with an order minimum of 100 count. So the buying unit is a 100-piece jar rather than individual screws - plan on that if you only need a handful for one box. The packaged jar weighs 4.47 lbs.
6) Do these Metallics machine screws meet Buy American or ARRA requirements on a federal job?
The JRM72SLT carries ARRA Compliant and Buy American Compliant flags in Metallics' product data, with country of origin listed as China. On a federally funded project where the specification demands domestic melt and manufacture, verify which standard your contract actually invokes, because the origin and the compliance flag point in different directions depending on the clause.
7) I need a different length or quantity in the Metallics JRM round head slotted line - is that possible?
Metallics states other sizes and quantities in the JRM round head slotted series are available by request beyond the 3/8-16 x 1-1/4 inch JRM72SLT. If you are standardizing a maintenance stock across several diameters and lengths, ask for the sizes you need rather than substituting a nearby length.
