Metallics JN163M – Frequently Asked Questions
1) Will the Metallics JN163M hex nut thread onto 1/4-20 all-thread rod?
Yes. The JN163M is a 1/4-20 hex nut, 20 threads per inch, cut to ASME B18.2.2, so it runs onto any standard 1/4-20 threaded rod, machine screw, or bolt. That makes it the usual nut for 1/4-20 trapeze and strut hanger rod on electrical and mechanical supports.
2) Is the JN163M strong enough to pair with a Grade 5 bolt?
No, not as a matched assembly. The JN163M is a Grade 2 steel nut, hardness Rockwell B68 to C32, which is intended for Grade 2 fasteners and general support work. If your drawing calls for a Grade 5 or Grade 8 bolt, specify a nut of matching grade so the nut is not the weak point in the joint.
3) What wrench or socket size fits a 1/4-20 Metallics hex nut?
Across the flats the nut measures 0.423 to 0.438 inch, which is the 7/16 inch hex a 1/4-20 nut normally takes. A 7/16 socket, open end, or nut driver seats it. Nut height runs 0.212 to 0.226 inch.
4) Can zinc plated steel hex nuts be used outdoors or in damp locations?
These are zinc plated steel, which is a dry indoor to lightly protected finish. Zinc gives some corrosion resistance but it is not a wet, coastal, or chemical environment nut. For exposed exterior runs, wash down areas, or anywhere standing moisture is expected, move to stainless steel hardware instead.
5) How many nuts come in a jar of Metallics JN163M, and can I buy fewer?
The JN163M ships as a jar of 1,000 nuts, and 1,000 is the order minimum, so it is sold by the full jar rather than loose by the piece. The jar is the right buy for a stocked gang box or shop bin; Metallics does offer other sizes and quantities by request.
6) Is this a finished hex nut or a jam nut?
It is a standard finished hexagonal nut, not a thin jam nut. Height is 0.212 to 0.226 inch, which is full nut height for a 1/4-20 under ASME B18.2.2. If you need a second locking nut stacked behind a first, order a thinner jam nut separately rather than using two of these where space is tight.
7) Does the JN163M hex nut meet Buy American and ARRA requirements on a public project?
The product record flags the JN163M as compliant for both Buy American and ARRA, while listing China as the country of origin. On a federally funded job where domestic melt and manufacture is enforced, confirm which compliance clause your contract cites, because origin and ARRA treatment are judged differently depending on the funding program.
8) How much does a 1,000 count jar of 1/4-20 zinc hex nuts weigh, and how big is the jar?
The full jar runs 7.17 lbs, measuring 3.5 inches in length and width by 5.75 inches in height. That is a one hand bin container, easy to drop in a van shelf or on a bench rather than needing a shelf pallet.
