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 JSN25316SS – Frequently Asked Questions
1) Will a Metallics JSN25316SS hex nut thread onto a 1/2-13 bolt?
Yes. The JSN25316SS is a 1/2 inch hex nut with 13 threads per inch, which is the standard UNC coarse pitch for 1/2 inch fasteners, so it mates with any 1/2-13 bolt, rod, or screw. Threads are made to ANSI/ASME B18.2.2.
2) Is 316 stainless worth it over 18-8 for outdoor or coastal mounting?
The JSN25316SS is made from 316 stainless steel, an austenitic alloy. Both 18-8 and 316 resist corrosion, but 316 has greater corrosion resistance and better strength at raised temperatures, which is why it gets specified for marine, coastal, chemical, and hot-service locations. For dry interior work 18-8 is usually sufficient.
3) Can I use a stainless hex nut on a grade 5 or grade 8 steel bolt?
Not recommended. Metallics specifies these 316 stainless nuts for use with stainless steel bolts and screws whose minimum tensile strength is equal to or less than the proof stress of the mating nut. A grade 5 or grade 8 alloy bolt is stronger than the stainless nut can hold, and mixing plain steel with stainless also sets up galvanic corrosion. Match the nut to a stainless bolt of equal or lower strength.
4) Do these stainless nuts meet Buy American or ARRA requirements for a public job?
No. The JSN25316SS hex nut is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project has domestic-sourcing language in the spec, these will not satisfy it.
5) What wrench or socket size fits these 1/2-13 stainless hex nuts?
Width across the flats runs 0.840 to 0.866 inches, so a 7/8 inch wrench or socket is the correct size. Nut height is 0.427 to 0.448 inches.
6) How many nuts come in a jar of Metallics JSN25316SS?
They ship 50 pieces to a jar, and 50 each is the order minimum. The packed jar weighs 1.82 lbs.
7) Will a 1/2-13 hex nut clear a tight pocket or recessed hole?
The nut body measures 0.840 to 0.866 inches across the flats and 0.427 to 0.448 inches thick, and thickness follows the standard 0.875 D relationship to nominal size with 1.5 D across the flats. Lay that against your pocket depth and the corner-to-corner swing before you commit, since a hex needs clearance at the points, not just the flats.
8) Are these hex nuts hard enough for strut, hanger rod, and conduit support work?
Hardness runs Rockwell B95 to C32. Metallics lists them for the electrical, plumbing, and heating and air conditioning trades, which covers strut, rod hanging, and conduit support where a corrosion-resistant 1/2-13 nut is called for.
9) Can I get this Metallics JSN hex nut in other sizes or pack quantities?
Yes. The JSN series 1/2-13 nut is stocked as a jar of 50, and Metallics notes other sizes and quantities are available by request.
