Metallics JNYN175SS – Frequently Asked Questions
1) What thread size and pitch does the Metallics JNYN175SS nylon insert lock nut take?
It's a 3/4-10 UNC right-hand thread, 10 threads per inch, cut to ANSI/ASME B1.1. So it mates with any standard 3/4 inch coarse-thread rod, bolt or anchor. If your rod is 3/4-16 fine thread, this is the wrong nut.
2) Does the Metallics JNYN175SS meet Buy American requirements for a government or public works job?
Metallics lists the JNYN175SS as both Buy American compliant and ARRA compliant, which is what public-funded and federal jobs typically ask for on fasteners. Country of origin is listed as multiple.
3) Will a nylon insert locknut hold up outdoors or in a wet location?
The nut body is 18-8 stainless steel, so it handles damp and outdoor exposure far better than plain or zinc-plated steel. For saltwater or heavy chloride exposure, 316 stainless is the usual step up. One caution with the nylon ring: it is a polymer element, so it is not intended for high-temperature service the way an all-metal prevailing torque nut is.
4) Can I reuse a nylon insert lock nut after I take it off?
The locking action comes from a nylon collar that the bolt threads cut into, so it loses grip each time it's removed. Standard practice is one or two uses at most, then replace. That's why these ship 50 to a jar rather than individually, and why the 50 piece jar is the order minimum.
5) Should I use a nylon insert locknut or a flat washer and jam nut on vibrating equipment?
For equipment that vibrates, a nylon insert nut like the JNYN175SS is the simpler fix: the nylon collar grips the bolt threads and resists back-off without a second nut or a thread locker. A jam nut stack takes two parts and more depth. Where service temperature is high, go to an all-metal prevailing torque nut instead, since the locking element here is nylon.
6) How hard is the nut, and will it strip on a stainless bolt?
Hardness runs Rockwell B95 to C35. Stainless on stainless is prone to galling under torque, so run it on slowly and use an anti-seize on the threads if you're pulling it to a high torque value.
7) How many nuts come in a jar and how much does it weigh for shipping?
Fifty nuts per jar, and 50 each is the order minimum. The jar weighs 6.1 lbs. Metallics offers other sizes and quantities in this JNYN series by request.
