Metallics JN163PL – Frequently Asked Questions
1) What thread size is the Metallics JN163PL hex nut, and will it fit a 1/4-20 bolt or threaded rod?
The JN163PL is a 1/4-20 hex nut, so 20 threads per inch on a 1/4 inch diameter. It threads onto any standard 1/4-20 UNC bolt, machine screw or 1/4-20 threaded rod. The thread conforms to ASME B18.2.2, which is the dimensional standard for hex nuts, so it mates with off-the-shelf 1/4-20 fasteners from other suppliers.
2) Are these plain steel nuts okay for outdoor or damp electrical work?
No. The JN163PL is plain finish steel with no plating or coating, so it will rust in wet or outdoor conditions. Keep these for dry indoor use (panel work, interior strut and bracket assembly). For exposed locations, order a zinc plated or stainless 1/4-20 hex nut instead.
3) What grade are these Metallics hex nuts, and are they strong enough for structural hanging?
These are Grade 2 steel nuts, hardness Rockwell B68 to C32. Grade 2 is general-purpose: fine for electrical mounting, boxes, brackets, light strut assembly and enclosure hardware. If your drawing calls for a Grade 5 or Grade 8 nut to match a high strength bolt, this is not the right nut, since the nut should match or exceed the bolt grade.
4) What wrench or socket size do I need for these 1/4-20 hex nuts?
Across the flats the nut measures 0.423 to 0.438 inch, which is a 7/16 inch wrench or socket. Nut height runs 0.212 to 0.226 inch.
5) How many nuts come in a jar of Metallics JN163PL, and can I buy fewer than 100?
They ship in a jar of 100 count, and 100 is the order minimum, so a jar is the smallest buy. The filled jar weighs 0.75 lbs. Other sizes and quantities are available by request.
6) Do these 1/4-20 hex nuts meet Buy American or ARRA requirements on a federal job?
The JN163PL is flagged compliant for both ARRA and Buy American in the manufacturer data, while country of origin is listed as China. If your contract enforces a domestic melt-and-manufacture clause, confirm the origin against your spec before you submit the material list.
7) Is a plain hex nut like this enough to hold on vibration, or do I need a locknut?
The JN163PL is a plain finished hex nut with no nylon insert and no distorted thread, so it has no locking feature. On equipment that vibrates (motors, fans, transformer mounts) pair it with a lock washer or step up to a nylon insert locknut in 1/4-20. For static electrical mounting it holds fine on its own.
8) Will the JN163PL work on 1/4-20 strut and channel hardware for conduit hanging?
Yes, as a thread match. It is a 1/4-20 nut built to ASME B18.2.2 hex nut dimensions, so it runs on 1/4-20 strut studs, trapeze rod and conduit clamp bolts. Note it is plain steel rather than plated, so use it inside dry areas; strut runs in parking garages, roofs or wash-down areas should get a plated or stainless nut. Also check that nothing on the hanger spec calls for a channel nut with a spring, which is a different part.
