Metallics JNYN161 – Frequently Asked Questions
1) What thread size is the Metallics JNYN161 nylon insert lock nut, and will it fit a 10-24 machine screw?
The JNYN161 is a 10-24 nylon insert hex lock nut, so it threads onto any #10-24 machine screw or bolt. The threads are cut to ANSI/ASME B1.1, with 24 threads per inch, which is the standard #10 coarse (UNC) pitch. It will not run onto a 10-32 fine thread screw.
2) Will a nylon insert locknut hold up on equipment that vibrates, like rooftop HVAC units?
Yes, that is the intended use. Metallics lists the JNYN161 for areas of high vibration and for the electrical, plumbing, heating and air conditioning trades, which covers mechanical equipment mounts, fan assemblies, and strut-hung work where a plain nut would back off.
3) Can I use these nuts on a federally funded or Buy American job?
No. The JNYN161 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-sourcing clause, you need a US-made nylon insert locknut instead.
4) What wrench or socket size do I need for a 10-24 nylon insert locknut?
Across the flats the JNYN161 measures 0.367 to 0.376 inch, which takes a 3/8 inch wrench or socket. Height across the nut runs 0.229 to 0.249 inch, so it sits low enough to clear most strut and box flanges.
5) Do I still need a lock washer if I use a nylon insert lock nut?
No. The nylon collar in the JNYN161 deforms around the screw threads and holds the nut against vibration, which eliminates the need for a lockwasher. That is the point of the design, and it saves you stocking a second item on the truck.
6) Are these 10-24 locknuts corrosion resistant enough for outdoor or damp locations?
The JNYN161 is steel with a zinc finish. Zinc plating handles indoor, dry, and normally damp interior work well, but it is a plated carbon steel nut, not stainless. For continuous outdoor exposure, wash-down areas, or coastal sites, specify a stainless nylon insert nut instead.
7) How many 10-24 nylon insert locknuts come in a jar, and what is the minimum I can order?
The JNYN161 ships as a jar of 100 nuts, and one jar is the order minimum. The filled jar weighs 0.54 lbs. Metallics offers other sizes and quantities by request if you need a different thread size for the same job.
8) Do these 10-24 locknuts meet a dimensional standard for spec work?
The JNYN161 is built to ASME B18.16.6, the dimensional standard for prevailing torque nuts, with threads to ANSI/ASME B1.1. If a submittal calls for a nylon insert hex locknut to B18.16.6, this one answers it.
9) Can these locknuts be reused after I take them apart?
A nylon insert nut relies on the plastic collar being cut by the screw threads the first time it is run on. After repeated removal the collar loses grip, so for an assembly you expect to service often, plan on fresh nuts each time. For a one-time mount, the JNYN161 is doing exactly what it was made for.
