Metallics JN166G – Frequently Asked Questions
1) Will the Metallics JN166G hex nut thread onto 1/2-13 all-thread rod?
Yes. The JN166G is a 1/2-13 hex nut, meaning a 1/2 inch nominal diameter with 13 threads per inch, which is the standard UNC coarse thread used on 1/2 inch all-thread rod and 1/2 inch hex bolts. It will not fit 1/2-20 fine thread hardware.
2) Will these Metallics nuts satisfy a Buy American or ARRA requirement on a public job?
No. The JN166G is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your specification carries a domestic sourcing clause, this part will not clear it.
3) What wrench or socket size do I need for a 1/2-13 Metallics galvanized hex nut?
Across the flats the nut measures 0.840 to 0.866 inches, so a 7/8 inch wrench or socket is the right tool. Corner to corner it runs 0.736 to 0.750 inches on the listed head width spec, and nut thickness is 0.427 to 0.448 inches.
4) Is the galvanized finish on these 1/2-13 hex nuts OK for damp or outdoor locations?
The JN166G is steel with a galvanized finish, which is the usual choice for strut, rod hangers and supports in damp interior and exterior locations where plain steel would rust. For continuously wet, coastal or chemically aggressive environments, stainless is the better call.
5) How many nuts come in a jar of Metallics JN166G?
They ship in a jar of 50, and 50 each is the order minimum, so you buy in full jars rather than loose counts. Metallics notes other sizes and quantities are available by request.
6) Can I use the JN166G hex nut on plumbing and HVAC hanger work, or is it electrical only?
It is sold through the electrical side but the stated field application covers electrical, plumbing, heating and air conditioning work. Any 1/2-13 threaded rod hanger, strut or trapeze assembly in those trades takes this nut.
7) How much does a jar of 50 Metallics 1/2-13 hex nuts weigh for shipping?
A jar weighs 1.92 lbs, and the jar itself measures 3 inches by 3 inches by 3.6 inches, so a few jars drop easily into a gang box or van bin.
