Metallics JN164BR – Frequently Asked Questions
1) What thread size is the Metallics JN164BR brass hex nut?
The JN164BR is a 5/16-18 hex nut, so 18 threads per inch on a 5/16 inch coarse thread, cut to ANSI/ASME B1.1. It will run onto any standard 5/16-18 UNC bolt, rod, or stud. If your rod is 5/16-24 fine thread, this is the wrong nut.
2) Will this brass nut fit a standard 1/2 inch wrench or socket?
No. Across the flats the JN164BR measures 0.922 to 0.938 inch, which is a 15/16 inch wrench or socket. Corner to corner it runs 1.051 to 1.083 inch, so allow that much clearance in a tight box or channel. Height is 0.535 to 0.559 inch.
3) Why use a brass hex nut instead of a steel one on electrical work?
Brass is the material here, and that is the reason electricians reach for it on grounding and bonding connections: brass mates with copper conductors and copper-alloy lugs without the galvanic mismatch you get pairing copper to plain or zinc-plated steel, and it does not rust in damp vaults, pits, or outdoor enclosures. For dry structural or strut work where conductivity is irrelevant, a plated steel nut is the usual choice.
4) Does the Metallics JN164BR meet a dimensional standard I can put on a submittal?
It is built to ASME B18.2.2, the dimensional standard for hex nuts, and the thread conforms to ANSI/ASME B1.1. Those are the two references a spec section normally calls for on a nut, and the published across-flats, across-corners, and height figures match that standard's envelope.
5) Is the JN164BR brass nut Buy American and ARRA compliant?
Both flags are marked compliant on the JN164BR. Country of origin is China. On federally funded work where the contract carries a domestic-content clause rather than a trade-agreement clause, confirm which one your spec section invokes before you submit it.
6) How many nuts come in a jar, and can I buy fewer than a full jar?
The JN164BR ships as a jar of 50, and 50 count is the order minimum, so the jar is the smallest unit. The filled jar runs 0.55 lbs. Metallics does make other sizes and quantities in the JN line by request.
7) Is the Metallics JN164BR a plain hex nut or a locknut?
It is a plain hexagonal nut in brass, 5/16-18. There is no nylon insert and no distorted thread, so it will back off under vibration on its own. On equipment pads, generators, or anything that shakes, add a lock washer, a jam nut, or thread locker.
8) What size is the jar itself for bin or truck stock storage?
The packaged jar of 50 measures 3 in by 3 in by 2.15 in and weighs 0.55 lbs, so it drops into a standard parts bin or a van drawer without repacking.
