Metallics JNYN167G – Frequently Asked Questions
1) What thread size is the Metallics JNYN167G nylon insert locknut?
The JNYN167G is a 5/8-11 hex nylon insert locknut, so it threads onto 5/8 inch coarse (UNC) bolts, rods, or threaded rod. The galvanized finish suits outdoor and damp-location work. It comes in a jar of 25.
2) Will the JNYN167G fit 5/8 inch threaded rod used for conduit and trapeze hangers?
Yes, provided the rod is 5/8-11 UNC, which is the standard coarse thread for 5/8 inch rod sold for hanger and trapeze work. The nut will not run on 5/8-18 fine thread. Match the hex size to your wrench or socket before you get on the lift.
3) How many nuts come in a jar of Metallics JNYN167G locknuts?
25 nuts per jar. The jar pack is the standard put-up, so an order quantity of one gets you 25 pieces of the 5/8-11 galvanized nylon insert locknut.
4) Will a nylon insert locknut hold on vibrating equipment without a separate lock washer?
That is what the nylon insert is for. The collar on the JNYN167G deforms around the bolt threads as the nut is run down, creating prevailing torque that resists back-off from vibration, so no split or tooth lock washer is needed. Use a flat washer if you need load spread on a soft or oversized-hole surface.
5) Is a galvanized nylon insert locknut OK outdoors or in a wet location?
Galvanized plating gives better corrosion resistance than plain or zinc-plated steel, so the JNYN167G is used on exterior conduit supports, rooftop racks, and damp interiors. One caution: the nylon insert is temperature limited compared with an all-metal lock nut, so for high-heat locations near boilers, flues, or luminaire ballast housings use an all-metal prevailing torque or jam nut instead.
6) Can I reuse a 5/8-11 nylon insert locknut after taking it off?
Reuse is limited. Once the nylon collar has been cut by the bolt threads it loses prevailing torque with each removal, and most specs treat nylon insert nuts as single-use for critical connections. On strut, hangers, and general electrical support work people do reuse them a couple of times, but for anything structural put a fresh nut on. The jar of 25 is sized for that.
