Metallics JNN151D – Frequently Asked Questions
1) What screw size does the Metallics JNN151D nylon hex nut thread onto?
It's a 3-48 nut, so it threads onto a #3 machine screw with 48 threads per inch, the UNF (fine) pitch for that diameter. A #3-56 or a coarse-thread screw will not engage it.
2) Is the JNN151D nut metal or plastic?
Nylon, not metal. That makes it non-conductive and non-corroding, which is why it gets used on small electrical terminations, instrument panels and PCB standoff work where a steel nut could short or rust. It also means you torque it by feel, not with a wrench on a spec value.
3) Will a nylon 3-48 nut hold up as well as a steel one on a vibrating panel?
No. A nylon hex nut like the JNN151D trades clamp load for insulation and corrosion resistance. If the joint carries real load or sees constant vibration, use a steel or stainless 3-48 nut, ideally with a lock washer, and save the nylon one for places where isolation between the fastener and the circuit matters more than strength.
4) What part number do I order for a Metallics 3-48 nylon hex nut?
Metallics part number JNN151D. That single MPN covers the 3-48 nylon hex nut, so there is no finish or size option to specify with it.
5) Can I use a nylon hex nut instead of a nylon insert lock nut?
They are not the same thing. The JNN151D is a solid nylon hex nut, nylon all the way through, chosen for electrical isolation. A nylon insert lock nut is a steel nut with a nylon collar and is chosen for vibration resistance. If you need the fastener itself to be non-conductive, the solid nylon nut is the right one; if you need it to stay put under vibration, it is not.
6) Is the Metallics 3-48 nylon hex nut made in the USA?
Yes, the JNN151D is USA made.
