Features
- Designed for use with stainless steel bolts and screws with a specified minimum tensile strength equal to or less than the specified proof stress of the mating nut. Both type of stainless are corrosion resistant with 316 stainless having greater such resistance as well as superior strength at raised temperatures.
- Six-sided internally threaded fastener whose thickness is 0.875 D is the nominal nut size and 1.5 D is their width across the flats, made from austenitic alloys.

Metallics JSN24 – Frequently Asked Questions
1) What thread size is the Metallics JSN24 hex nut, and will it fit a 1 inch UNC bolt?
The JSN24 is a 1-8 hex nut, meaning a 1 inch nominal thread at 8 threads per inch. That is standard 1 inch UNC coarse thread, so it mates with any 1-8 UNC bolt, rod, or stud. It is made to ANSI/ASME B18.2.2 dimensional standards for hex nuts.
2) Is the JSN24 nut 18-8 or 316 stainless?
18-8 stainless (type 304 family austenitic). If your application is marine, coastal, or involves raised service temperatures, 316 is the grade to specify instead, since it carries greater corrosion resistance and better strength at elevated temperature. For general outdoor and indoor electrical and structural work, 18-8 is the usual choice.
3) What bolts should I pair these stainless nuts with so the joint doesn't fail?
Pair the JSN24 with stainless bolts or screws whose specified minimum tensile strength is equal to or less than the specified proof stress of the nut. Hardness on the nut is Rockwell B80 to C32. Running a higher strength bolt than the nut can carry means the nut strips before the bolt yields, which is the failure you do not want in a hanger or strut connection.
4) What wrench or socket size do I need for a 1-8 stainless hex nut?
Width across the flats on the JSN24 runs 1.450 to 1.500 inches, so a 1-1/2 inch wrench or socket is the size to bring. Corner to corner measures 1.653 to 1.732 inches, which matters if you are working in a tight pocket or against a conduit run.
5) How thick is the JSN24 nut? I need to know how much bolt thread to leave.
Nut height is 0.831 to 0.887 inches, consistent with the standard 0.875 D thickness for a hex nut at this nominal size. Figure roughly 7/8 inch of engagement plus a couple of threads past the face when you cut rod or pick bolt length.
6) How many nuts come in a jar, and can I buy fewer than 50?
The JSN24 ships 50 count in a jar, and 50 is the order minimum, so the jar is the smallest unit. Metallics does offer other sizes and quantities by request if you need a different pack.
7) Does the JSN24 stainless nut meet Buy American and ARRA requirements for a public project?
Both the Buy American and ARRA compliance flags on the JSN24 are marked C. Country of origin is China, so if your specification requires domestic melt and manufacture rather than compliance classification, confirm that against the project's exact clause before you submit it.
8) Can I use these stainless hex nuts on threaded rod for overhead conduit and strut hangers?
Yes, as long as the rod is 1 inch 8 TPI coarse thread. The JSN24 is a six sided internally threaded nut in 18-8 stainless made to ANSI/ASME B18.2.2, so it runs on standard 1-8 all thread used for trapeze hangers and strut. Stainless is the right call where galvanized would corrode, such as wash down areas or exterior runs.
9) How heavy is a jar of 50 of the 1-8 stainless nuts?
A jar of the JSN24 weighs 13.4 lbs and the packed jar measures 7.25 x 6.75 x 3.25 inches. Worth knowing if you are staging material in a gang box or hand carrying to a roof.
