Metallics JNN163 – Frequently Asked Questions
1) What thread size are the Metallics JNN163 nylon insert hex nuts?
The JNN163 is a 1/4-20 hex nut with a nylon insert, so it threads onto any standard 1/4-20 UNC bolt, screw, or threaded rod. The nylon ring at the top of the nut grips the male thread and resists loosening from vibration, which is why these get used on equipment mounts, strut assemblies, and panel hardware rather than a plain hex nut.
2) How many nuts come in a jar of Metallics JNN163?
Fifty nuts per jar. The JNN163 ships as a jar pack, which is the handy size for a service van or a shop bin rather than a bulk box, so one jar covers a typical day of fixture or equipment mounting at 1/4-20.
3) Can I reuse a nylon insert lock nut like the JNN163, or is it one-time use?
Nylon insert nuts hold their grip because the collar deforms around the male thread the first time they are run on. Each time you back a JNN163 off and reinstall it, that grip drops off, so for anything carrying load or vibration the practice is to install a fresh nut from the jar. With 50 in a jar that is rarely an issue on the job.
4) Will a nylon insert nut work in a high heat location like a ballast housing or near a motor?
The locking element here is nylon, not metal, so it is not the fastener for sustained high temperature service. For hot locations use an all metal locking nut or a plain hex nut with a lock washer. The JNN163 is intended for normal interior electrical and equipment work where vibration, not heat, is the problem being solved.
5) What is the Metallics part number to order for a 1/4-20 nylon lock nut?
Order JNN163. That is the Metallics manufacturer part number for the 1/4-20 hex nut with nylon insert in the 50 count jar, and it is the number to quote so you do not end up with a plain hex nut or a different thread pitch.
6) Do I need a lock washer with these nuts?
No. The nylon insert does the job a lock washer would do, so the JNN163 is used with a plain flat washer, or on its own against a bolted flange. Stacking a split lock washer behind a nylon insert nut is redundant and only adds height to the stack.
