Metallics JNYN170 – Frequently Asked Questions
1) What thread size does the Metallics JNYN170 nylon insert lock nut take?
It's a 12-24 nut, meaning a #12 screw at 24 threads per inch, cut to the UNC coarse series and right-hand thread. The thread conforms to ANSI/ASME B1.1, so it mates with any standard 12-24 machine screw or bolt, including the 12-24 screws used in equipment racks and enclosure hardware.
2) Do these locknuts meet a dimensional standard so they interchange with what's already on the job?
Dimensions follow ASME B18.16.6, the standard for prevailing-torque hex nuts, and the threads follow ANSI/ASME B1.1. That means the 12-24 JNYN170 nut is dimensionally interchangeable with any other standards-made 12-24 nylon insert hex locknut already installed, same wrench size, same thread engagement.
3) Will a nylon insert locknut hold up in a hot location like a light fixture or motor housing?
The locking element is nylon, so it's a mechanical prevailing-torque lock rather than a heat-tolerant one. These are steel nuts with a zinc finish and work well on vibration-prone dry interior assemblies: strut, enclosures, equipment racks, panel mounting. For high-temperature spots, specify an all-metal lock nut or a flange nut with a toothed bearing face instead.
4) Should I use a nylon insert locknut or a plain nut with a lock washer?
A nylon insert nut locks by thread friction through the whole run-down, so it resists loosening under vibration without needing a washer and without marring the mating surface. A plain nut plus a split washer relies on clamp load and bites into the part. For panelboard, strut, and enclosure work where you want reusable hardware and no surface damage, the nylon insert version is the simpler call. Keep in mind nylon insert nuts lose locking effectiveness after repeated reuse, so replace rather than recycle them on anything critical.
5) Can I use the Metallics JNYN170 locknuts on a federally funded or Buy American job?
They're flagged compliant for both ARRA and Buy American purposes. Country of origin is listed as multiple, so if your spec requires a documented single source of manufacture, confirm the origin on the lot you receive before submitting it.
6) How are these 12-24 locknuts packaged, and what's the smallest quantity I can buy?
They ship in a jar of 100, and 100 count is the order minimum. The jar weighs 0.91 lbs and measures 3 x 2.15 x 3 in., so it fits a van bin or a service cart drawer without repacking.
7) Are zinc-plated steel locknuts okay outdoors or in a damp mechanical room?
Zinc plating over steel gives moderate corrosion resistance, which suits dry interior and sheltered applications. For sustained wet exposure, coastal air, or washdown areas, step up to stainless. The silver zinc finish on these also matches typical zinc-plated strut and enclosure hardware if you're standardizing a look across an install.
8) I need the same nylon insert locknut in 1/4-20 and 10-32. Does Metallics make other sizes in this series?
Yes. The JNYN series covers additional thread sizes and pack quantities beyond the 12-24 jar of 100, available by request. Tell us the thread size and count you need and we'll pull the matching JNYN part.
