Metallics JN163BR – Frequently Asked Questions
1) What thread does the Metallics JN163BR brass hex nut take?
It's a 1/4-20 nut, so 20 threads per inch on a 1/4 inch coarse (UNC) thread, cut to ANSI/ASME B1.1. It will thread onto any standard 1/4-20 machine screw, bolt, or threaded rod.
2) Will a standard 7/16 inch wrench fit these 1/4-20 brass hex nuts?
Yes. Across the flats the nut measures 0.423 to 0.438 inch, which is the standard 7/16 inch hex for a 1/4-20 nut, so a 7/16 wrench, socket, or nut driver fits. Corner to corner it runs 0.488 to 0.505 inch and height is 0.212 to 0.226 inch, so plan clearance accordingly in a tight box or channel.
3) Can I use Metallics JN163BR nuts on a federally funded Buy American or ARRA job?
No. The JN163BR is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a project with domestic-sourcing requirements you'll need a documented domestic brass nut instead.
4) Why use a brass nut instead of a steel or zinc-plated one on electrical work?
Brass is non-magnetic, corrosion resistant, and conducts, which is why these are specified for grounding and bonding connections, panel and enclosure hardware, and damp-location assemblies where plated steel would rust. The JN163BR is solid brass, and Metallics lists it for the electrical, plumbing, heating and air conditioning trades. Brass is softer than steel, so it is not the right nut for a high-torque structural joint.
5) Does the JN163BR hex nut meet a recognized dimensional standard for spec work?
It is made to ASME B18.2.2, the standard that governs hex nut dimensions, with threads per ANSI/ASME B1.1. That is the pair of standards a submittal or inspector normally asks for on a fastener callout.
6) How are these 1/4-20 brass nuts packaged and what is the minimum order?
They ship in a jar of 100, and the jar is the minimum order unit, so 100 pieces is the smallest quantity. Jar weight is 0.71 lbs. Metallics also offers other sizes and quantities in the JN series by request.
7) What size shelf or bin space does a jar of Metallics JN163BR nuts take up?
The jar measures 3 in by 3 in with a height of 2.15 in, so it drops into a standard small parts bin on a service van or stockroom shelf without repackaging.
