Metallics JNCHTL38SS – Frequently Asked Questions
1) What thread size and pitch does the Metallics JNCHTL38SS locknut take?
It is a 3/8-16 nut, so it threads onto 3/8 inch rod or bolts with 16 threads per inch. That is the standard UNC coarse pitch for 3/8 inch fasteners, which is what 3/8 inch threaded rod used for hanging conduit, strut, and fixtures is cut to. It will not run on 3/8-24 fine thread.
2) Is the JNCHTL38SS stainless, and can it go outdoors or in a damp location?
The nut is 18-8 stainless steel, the common 300 series austenitic grade, so it holds up to outdoor and damp-location service far better than a zinc plated nut. That makes it a reasonable pick for exterior lighting supports, rooftop conduit racks, and wash-down areas. Pair it with stainless rod or bolts to avoid mixing metals.
3) Will the JNCHTL38SS work on 3/8 inch threaded rod for hanging conduit and strut?
Yes. Rod used for electrical hanging work in 3/8 inch size is cut 3/8-16, which is exactly what this nut takes. Being 18-8 stainless, it also matches stainless rod and strut hardware on exterior or corrosive runs.
4) What is a hex top locknut and when would I use one instead of a plain hex nut and lock washer?
A top locknut is a hex nut with a prevailing-torque locking feature at the top of the nut, so it resists backing off under vibration without any separate washer. On vibrating equipment, fan and motor mounts, or conduit racks near mechanical gear, it replaces the nut-plus-lock-washer stack with one part. Use a plain hex nut where you expect to break the joint down and reuse the hardware often.
5) How many nuts come in the Metallics JNCHTL38SS and how are they packaged?
One hundred nuts, supplied in a jar. The jar pack suits a van or shop bin where you are pulling a few at a time rather than a bulk box you have to decant.
6) What part number do I order for a 3/8-16 stainless top locknut from Metallics?
The manufacturer part number is JNCHTL38SS, and it is the single model offered for this 3/8-16 18-8 stainless hex top locknut in the 100 count jar.
