Metallics JNYN167 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JNYN167 nylon insert lock nut?
It is a 5/8-11 nut, meaning a 5/8 inch nominal diameter with 11 threads per inch, cut to the ANSI/ASME B1.1 thread standard. That is the UNC (coarse) pitch for 5/8 inch, so it threads onto standard 5/8-11 coarse bolts, rods and all-thread. It will not run on 5/8-18 fine thread.
2) Do I still need a lock washer with a nylon insert lock nut?
No. The nylon collar in the JNYN167 grips the bolt threads and holds the nut in place, which eliminates the need for a lockwasher. That saves a part in the stack and a step on the install, and it is why these get specified in areas of high vibration.
3) Is the Metallics JNYN167 locknut a standard dimension nut or a proprietary size?
It is built to ASME B18.16.6, the dimensional standard for prevailing torque nylon insert lock nuts, with threads to ANSI/ASME B1.1. So it interchanges dimensionally with any other B18.16.6 5/8-11 hex nylon insert locknut and drops into standard hole patterns and clearances.
4) Is a zinc plated steel locknut OK for outdoor or damp locations?
The JNYN167 is steel with a zinc finish. Zinc plating handles indoor and protected applications well, including the electrical, plumbing and HVAC work it is intended for. For sustained outdoor exposure, wet locations or corrosive environments, step up to stainless rather than zinc plated steel.
5) Are Metallics JNYN167 locknuts acceptable on a Buy American or ARRA funded job?
No. The JNYN167 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements, specify a domestically manufactured locknut instead.
6) Should I use a nylon insert locknut or a double nut on threaded rod hangers?
A nylon insert nut gives you locking in a single piece and no lockwasher, which is why it shows up on electrical, plumbing and HVAC hanger work and anywhere there is real vibration. A jam nut arrangement takes two nuts, more rod length and more labor. Where the nylon nut does not belong is heat: the insert is plastic, so for high temperature service or anywhere a flame could reach it, use an all-metal prevailing torque nut.
7) How does the Metallics 5/8-11 locknut come packaged, and what is the minimum I can buy?
These 5/8-11 nylon insert locknuts ship in a jar, with a minimum order of 25 each. Jar weight is listed at 2.19 lbs. Other sizes and quantities are available by request.
8) Can I reuse a nylon insert locknut after taking it off?
Nylon insert locknuts like the JNYN167 rely on the nylon collar deforming around the bolt threads, and that grip weakens each time it is run on and off. For a vibration application, which is what these are specified for, use a fresh nut on reassembly rather than the one you backed off. Buying by the jar makes that practical.
