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 JSN16D – Frequently Asked Questions
1) What thread size are the Metallics JSN16D stainless hex nuts, and will they fit 3/8 inch all-thread rod?
The JSN16D is a 3/8-16 hex nut, so 16 threads per inch on a 3/8 inch nominal diameter. That is standard UNC coarse thread, which is what 3/8 inch all-thread rod used for hanging strut, conduit and fixture supports is normally cut to. It will not run on 3/8-24 fine thread.
2) Is the Metallics JSN16D nut 304 or 316 stainless?
It is 18-8 stainless, the austenitic 300 series grade commonly supplied as 304. 316 is the alloy you want if the nuts sit in coastal salt air, a wastewater plant, a pool room or a chemical wash-down area, since 316 gives greater corrosion resistance and better strength at raised temperatures. For general indoor and normal outdoor electrical work, 18-8 is the usual choice.
3) Are these hex nuts made in the USA and acceptable on a Buy American job?
Country of origin is the United States, and Metallics flags the JSN16D as both Buy American compliant and ARRA compliant. That covers the usual federal, municipal and school district procurement language on domestic fasteners.
4) What size wrench or socket do I need for these 3/8-16 stainless hex nuts?
Width across the flats runs 0.628 to 0.650 inch, which is a 5/8 inch wrench or socket. Nut height is 0.320 to 0.337 inch, so it is a standard pattern hex nut rather than a jam nut or a heavy hex.
5) Do these stainless hex nuts meet a recognized dimensional standard for spec work?
Yes. The JSN16D is made to ANSI/ASME B18.2.2, the dimensional standard for hex nuts, so the across-flats and thickness figures match what a drawing calling out a 3/8-16 hex nut expects. Hardness runs Rockwell B95 to C32.
6) Can I use these stainless nuts with any 3/8-16 bolt, or do the bolts need to be stainless too?
Match them to stainless bolts and screws whose specified minimum tensile strength is equal to or less than the proof stress of the nut. Pairing a stainless nut with a high strength plated steel bolt risks the nut stripping before the bolt reaches its rated load, and it also sets up dissimilar metal contact in wet locations. Keep the assembly stainless throughout.
