Metallics JNYN173 – Frequently Asked Questions
1) What thread does the Metallics JNYN173 nylon insert lock nut take?
It threads onto 7/16 inch bolts and rod at 20 threads per inch, right hand. The threads are cut to ANSI/ASME B1.1, so it mates with any standard 7/16-20 bolt, stud, or threaded rod.
2) How tall is the nut, and will it fit in a tight channel or strut run?
Overall height runs 0.438 to 0.468 inch, which is taller than a plain hex nut of the same thread because of the nylon collar at the top. Allow close to a half inch of bolt projection above the work plus thread stick-through to engage the insert, or the nylon never grips.
3) Will a nylon insert locknut hold up on vibrating equipment like fan or motor mounts?
That is what the nylon collar is for. The insert deforms around the bolt threads and resists back-off from vibration without needing a lock washer or thread adhesive. One caution for MRO crews: nylon insert nuts are intended as single-use prevailing torque fasteners, so plan on fresh nuts after a teardown rather than reusing the ones you removed. They are also a poor choice near high heat, where an all-metal lock nut is the better call.
4) Are these zinc plated steel nuts okay for damp indoor electrical work?
The JNYN173 is steel with a zinc finish, silver in appearance. Zinc plating handles normal indoor and protected-area service fine. For wet exterior, coastal, or corrosive locations, stainless or hot dip galvanized hardware is the right spec instead.
5) How are these locknuts packaged and what is the minimum I can buy?
They come 100 to a jar, and 100 count is the order minimum. The jar packaging is handy for a shop bench or a service van drawer, and the jar weighs about 2 lbs.
6) Do these nuts meet a dimensional standard I can put on a submittal?
Yes. The JNYN173 is built to ASME B18.16.6 for the nut dimensions and ANSI/ASME B1.1 for the threads, both American Standard dimensions. That is enough to call it out on a spec sheet or submittal for a standard 7/16-20 prevailing torque nut.
7) Can I get this Metallics nylon insert locknut in other thread sizes or larger quantities?
The JNYN series covers other sizes and pack quantities beyond the 7/16-20 jar of 100, available by request. If you are standardizing a facility or a fleet of panels on one lock nut, ask for the size list rather than mixing brands across the job.
8) Is the JNYN173 Buy American or ARRA compliant for a government job?
Country of origin on the JNYN173 is listed as multiple, so it should not be relied on for Buy American or ARRA domestic-content requirements. For federally funded work where domestic sourcing is written into the spec, source a fastener with a single declared US origin.
