Metallics JNYN159 – Frequently Asked Questions
1) What thread size is the Metallics JNYN159 nylon insert lock nut?
It's a 6-32 nut, meaning a #6 machine screw thread at 32 threads per inch, cut to the ANSI/ASME B1.1 thread standard. It will thread onto any standard 6-32 machine screw or stud, which is the size most commonly used for device mounting screws, cover plates, and small bracket work.
2) Do I still need a lock washer if I use a nylon insert lock nut?
No. The nylon collar inside the nut grips the screw threads and resists loosening on its own, so the JNYN159 takes the place of a separate lockwasher in the stack. That also means one less loose part to handle overhead in a panel or box.
3) Will a 6-32 nylon lock nut hold up on equipment that vibrates?
That's exactly what it's specified for. Metallics lists the application as areas of high vibration along with the electrical, plumbing, and heating and air conditioning trades. The nylon insert keeps tension on the threads so the nut doesn't back off under cyclic movement, which is where a plain hex nut fails.
4) Are Metallics JNYN159 lock nuts Buy American or ARRA compliant for a government job?
No. The JNYN159 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic-sourcing clause, this part won't satisfy it.
5) Can I use these nuts outdoors or in a damp location?
The nut is steel with a zinc finish, which gives ordinary indoor and protected corrosion resistance. Zinc plating is fine for panels, boxes, and mechanical rooms, but for continuous wet exposure, coastal air, or washdown areas you want stainless rather than zinc-plated steel.
6) How many 6-32 lock nuts come in a jar, and is there a minimum order?
Each jar holds 100 nuts, and the jar is the order unit with a 100-piece minimum. Metallics notes other sizes and quantities are available by request, so if you're standardizing a shop on a different thread size the series covers it.
7) Is there a temperature limit to watch for with nylon insert lock nuts?
Yes, and it's the one real limitation. The locking element is nylon, so this style of nut is not the right choice next to high-heat equipment, on flues, or anywhere a torch will be used nearby. For hot service use an all-metal prevailing-torque or deformed-thread lock nut instead. For the mechanical and electrical work Metallics calls out, electrical, plumbing, heating and air conditioning, ambient temperatures are no issue.
8) Can nylon insert lock nuts be reused after I take the assembly apart?
Treat them as limited-reuse. The locking action comes from the nylon collar deforming around the screw threads, so it loses grip each time it's run on and off. For a joint that gets serviced repeatedly, plan on a fresh nut from the jar of 100 rather than reinstalling the old one.
