Metallics JNCHTL58 – Frequently Asked Questions
1) What thread size does the Metallics JNCHTL58 locknut take?
The JNCHTL58 is a 5/8-11 locknut, so it threads onto 5/8 inch rod or bolt with 11 threads per inch (standard UNC coarse thread for that diameter). It will not run on 5/8-18 fine thread.
2) Will a 5/8-11 top locknut hold on threaded rod hanging a trapeze or strut rack?
Yes. A top locknut is a hex nut with a deformed crown that grips the male thread, so it resists backing off under vibration, which is the usual failure on overhead rod supports. The JNCHTL58 matches 5/8-11 rod. Run it on the loaded side of the connection and torque to the rod spec your drawing calls for.
3) Is the Metallics JNCHTL58 nut steel or stainless, and can I use it outdoors?
It is steel with a yellow zinc (zinc dichromate) plating. That is a mild indoor and dry-location coating. For wet exterior, corrosive, or marine conditions, step up to a stainless or hot dip galvanized 5/8-11 locknut instead.
4) How many nuts come in a jar of Metallics JNCHTL58?
Twenty-five nuts per jar. Metallics packs this one in a jar rather than a box, which is the handy count for a service van or a gang box rather than a bulk rack install.
5) Can a 5/8-11 top locknut be reused after it is removed?
Treat it as single use. A top locknut gets its holding power from the crown being deformed over the mating thread, and that deformation relaxes once the nut has been run on and backed off. Pull a fresh one from the jar of 25 on reassembly.
6) Do I need a lock washer with the Metallics JNCHTL58 locknut?
No. The locking is built into the nut's crown, so a split or tooth lock washer is redundant. Use a flat washer if you need to spread bearing load on strut, channel, or a slotted bracket.
7) What is the right wrench or socket for a 5/8-11 hex locknut?
The JNCHTL58 is a hex nut, so a standard wrench or socket fits the flats. Standard hex nuts in 5/8-11 take a 15/16 inch wrench, though a top locknut's crown sits slightly taller than a plain nut, so a deep socket is easier to seat than a shallow one.
