Metallics JNCHTL34 – Frequently Asked Questions
1) What thread size is the Metallics JNCHTL34 locknut, and will it fit 3/4 inch threaded rod?
It's a 3/4-10 nut, so it threads onto standard 3/4 inch coarse-thread rod or bolts (10 threads per inch, the UNC pitch for that diameter). If your rod is 3/4-16 fine thread, this is the wrong nut.
2) Is the JNCHTL34 a prevailing-torque locknut or does it use a nylon insert?
The JNCHTL34 is a hex top locknut, meaning the locking action is in the deformed top of the steel nut itself rather than a nylon insert. That makes it reusable in a way a nylon-insert nut is not, and it does not have the temperature limit a plastic insert brings.
3) What finish is on this 3/4-10 locknut, and is it suitable for damp or outdoor electrical work?
Steel with a yellow zinc plating (St-YZ). Yellow zinc gives better corrosion resistance than clear zinc for indoor and sheltered work, hanging strut, rod, and conduit supports. For sustained outdoor exposure or wet locations, specify hot-dip galvanized or stainless instead.
4) Can I use the JNCHTL34 locknut on vibrating equipment mounts instead of adding a jam nut?
That's what a top locknut is for. The prevailing-torque top resists loosening under vibration, so you don't need a second jam nut or a lock washer on the stack. It's a 3/4-10 nut, so it only suits 3/4 inch coarse-thread fasteners.
5) How many nuts come in a jar of the Metallics JNCHTL34?
25 nuts per jar, and the jar is the pack form. That is a shop-stock quantity for an electrician or MRO crib rather than a bulk box, so for large rod-hanging runs plan on multiple jars.
6) What part number do I order for a 3/4-10 steel yellow zinc top locknut from Metallics?
Metallics part number JNCHTL34 covers the 3/4-10 hex top locknut in steel with yellow zinc, supplied 25 to a jar. There is one configuration under that number, so no finish or size suffix to pick.
