Additional Notes
- Other sizes and quantities available by request
Features
- 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.
- 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.

Metallics JSN34 – Frequently Asked Questions
1) What thread size is the Metallics JSN34 hex nut, and will it fit a 3/4 inch UNC bolt?
The JSN34 is a 3/4-10 hex nut, so 10 threads per inch, which is the standard UNC coarse pitch for 3/4 inch bolts and all-thread rod. It mates with any 3/4-10 coarse-thread bolt, screw or rod. It will not thread onto 3/4-16 fine thread.
2) What grade of stainless are these 3/4-10 hex nuts, and are they OK outdoors or in a wet location?
Material is 18-8 stainless steel, an austenitic corrosion-resistant alloy, which is why these get used on exterior strut, rooftop and damp-location work rather than plated carbon steel. If the environment is chloride heavy (coastal, pool chemistry, de-icing salt) 316 stainless has greater corrosion resistance and better strength at raised temperatures, so specify 316 for those jobs instead.
3) Can I use these stainless nuts with any 3/4 inch bolt, or does the bolt have to match?
Pair them with stainless steel bolts and screws whose specified minimum tensile strength is equal to or less than the specified proof stress of the nut. Mating a high-strength carbon steel bolt to an 18-8 stainless nut can strip the nut and also sets up galvanic contact between dissimilar metals, so keep the stainless bolt with the stainless nut.
4) What wrench or socket size do I need for a 3/4-10 stainless hex nut?
Width across the flats on the JSN34 runs 1.088 to 1.125 in., so a 1-1/8 inch wrench or socket is the one to bring. Height across the hex corners measures 1.240 to 1.299 in., which is what matters if you are working in a tight channel or next to a wall.
5) Do these Metallics hex nuts meet a dimensional standard I can put on a submittal?
Dimensions conform to ANSI/ASME B18.2.2, the standard for hex nuts, so the across-flats, across-corners and thickness values are to spec and interchangeable with any other B18.2.2 3/4-10 hex nut on the job.
6) How are the JSN34 nuts packaged and what is the minimum I can order?
They ship 25 count in a jar, and 25 pieces is the order minimum. Total shipping weight is 2.91 lbs for the jar. Other sizes and quantities are available by request if 3/4-10 in a 25 pack is not what the job needs.
7) Are Metallics JSN34 stainless hex nuts acceptable on a Buy American or ARRA funded project?
Both the ARRA and Buy American compliance flags on the JSN34 read compliant. Country of origin is listed as China, so if your specification demands domestic melt and manufacture rather than ARRA/BAA compliance as flagged, confirm which test your project is being held to.
