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 JSN22316SS – Frequently Asked Questions
1) What thread does the Metallics JSN22316SS hex nut take, and will it fit a 7/8 inch bolt?
It is a 7/8-9 hex nut, meaning 7/8 inch nominal size with 9 threads per inch, which is the standard UNC coarse pitch for 7/8 inch. It threads onto any 7/8-9 UNC bolt or rod. It will not fit 7/8-14 fine-thread fasteners.
2) Is the Metallics JSN22316SS nut 316 stainless or 18-8?
316 stainless steel. Compared with 18-8, 316 gives greater corrosion resistance and better strength at elevated temperatures, which is why it gets specified for coastal, marine, wastewater, and chemical exposure rather than general indoor work.
3) Can I use this stainless nut on a Grade 5 or Grade 8 steel bolt?
It is intended for stainless steel bolts and screws whose specified minimum tensile strength is equal to or less than the proof stress of the mating nut. Pairing a stainless nut with a higher-strength alloy bolt like Grade 5 or Grade 8 puts the nut as the weak link, so match it to stainless fasteners. There is also a galvanic consideration mixing stainless nuts onto plain or galvanized steel bolts in wet service.
4) How many nuts come in a jar of Metallics JSN22316SS, and is there an order minimum?
They ship 25 to a jar, and 25 count is the order minimum. Total shipping weight of the jar is 5.18 lbs. Other sizes and quantities are available by request.
5) Does this hex nut meet a dimensional standard I can put on a submittal?
Dimensions conform to ANSI/ASME B18.2.2, the standard for hex nuts, so it interchanges with any other B18.2.2 7/8-9 hex nut on dimensions. Hardness is Rockwell B95-C32.
6) Will a 7/8-9 316 stainless hex nut work for a federally funded job with domestic sourcing requirements?
The JSN22316SS is flagged compliant for both ARRA and Buy American purposes in our product data. Country of origin is China, so if your specification demands a domestically manufactured fastener rather than compliance under the program flags, verify against your project's exact clause.
7) Is this a plain hex nut or a flange, nylon lock, or jam nut?
It is a plain six-sided internally threaded finished hex nut in austenitic stainless, with no flange, nylon insert, or locking feature. At 0.724 to 0.776 inches thick it is a standard-pattern nut, not a thin jam nut. If you need vibration resistance, you will want a lock washer, a nylon insert nut, or thread locker in addition.
