Metallics JNN164 – Frequently Asked Questions
1) What thread size is the Metallics JNN164 hex nut?
The JNN164 is a 5/16-18 hex nut, so it threads onto any 5/16 inch coarse-thread bolt, rod, or screw. 18 threads per inch is the standard coarse pitch for 5/16 inch fasteners, so it mates with common 5/16-18 machine bolts, hanger rod, and strut hardware. It will not thread onto 5/16-24 fine-thread fasteners.
2) Is the JNN164 a nylon insert lock nut or a plain hex nut?
It is a nylon insert hex nut (the "Hx Nut Ny" callout). The nylon collar at the top grips the bolt threads and resists loosening from vibration, which is why these get used on vibrating equipment mounts, fan and motor hardware, and overhead support assemblies rather than a plain finished hex nut.
3) How many nuts come in a jar of Metallics JNN164?
Each jar holds 50 of the 5/16-18 nylon insert hex nuts. The jar pack is the shop-bin format, so it suits a service van or a maintenance crib where you pull a handful at a time instead of buying a bulk box.
4) Should I use a nylon insert nut or a plain hex nut with a lock washer on electrical equipment mounts?
A nylon insert nut such as the JNN164 handles vibration on its own and needs no extra washer, which makes it the simpler choice on motor, fan, and equipment mounting where the joint sees movement. A plain nut with a lock washer is the alternative when the connection runs hot enough to degrade nylon, or where a nut needs to be removed and reinstalled repeatedly, since the nylon version does not hold its grip after the first installation.
5) Can I reuse a nylon insert lock nut like the JNN164 after taking it off?
Treat them as single use. The nylon collar is deformed by the bolt threads the first time it is run on, so a removed nut loses prevailing torque and the locking action is no longer reliable. With 50 nuts in the jar, the practical approach on a 5/16-18 connection is to fit a fresh one each time the joint is broken.
