Metallics JNCHTL12SS – Frequently Asked Questions
1) What thread size and pitch is the Metallics JNCHTL12SS locknut?
It's a 1/2-13 thread, meaning a 1/2 inch nominal diameter with 13 threads per inch. That's the standard UNC coarse pitch for 1/2 inch, so it mates with 1/2-13 all-thread rod, hanger rod, and 1/2 inch coarse bolts used on strut, trapeze, and conduit hanger assemblies.
2) Is the Metallics JNCHTL12SS nut stainless steel, and which grade?
18-8 stainless steel, the 300-series austenitic grade (roughly 18% chromium, 8% nickel) commonly used where carbon steel would rust. It's the usual pick for damp, outdoor, or washdown locations and for pairing with stainless rod or strut so you aren't mixing metals.
3) Will this locknut work on 1/2 inch threaded rod used for conduit and trapeze hangers?
Yes, as long as the rod is 1/2-13 coarse thread, which is the standard for electrical hanger and trapeze rod. The JNCHTL12SS threads straight on and locks without a washer. It will not fit 1/2-20 fine thread or 3/8-16 rod.
4) What is a hex top locknut and does it need a lock washer?
A hex top locknut is a prevailing-torque nut: the top of the nut is deformed so it grips the bolt threads and resists backing off under vibration. No separate lock washer is required. The JNCHTL12SS is the all-metal type in 18-8 stainless, so there's no nylon insert to worry about in a hot location.
5) How many nuts come in the Metallics JNCHTL12SS package?
Fifty nuts, packed in a jar rather than a bag or box, which is how electrical shops usually want loose fasteners for the van or bench. One jar covers 50 locknut points at 1/2-13.
6) Can a stainless 1/2-13 top locknut be reused once it's been taken off?
Prevailing-torque locknuts like this one lose grip each time they're run on and off, so for a connection you're relying on to stay tight, use a fresh nut from the jar instead of reinstalling one you removed. At 50 per jar there's room to do that.
7) What size wrench or socket fits the Metallics JNCHTL12SS nut?
It is a hex nut in 1/2-13, so a standard 3/4 inch wrench or socket is the normal fit for a 1/2 inch hex nut. Drive it with a wrench rather than an impact where you can, since all-metal prevailing-torque nuts run on with resistance for the full length of travel.
