Metallics JNYN173SS – Frequently Asked Questions
1) What thread does the Metallics JNYN173SS locknut take, 7/16-20 fine or 7/16-14 coarse?
Fine thread only. The JNYN173SS is a 7/16-20 UNF nut, 20 threads per inch, right hand, cut to ANSI/ASME B1.1. It will not run onto a 7/16-14 UNC coarse bolt, so check the bolt before you order a jar of 100.
2) Are these stainless locknuts OK for outdoor and damp electrical work?
Yes. These are 18-8 stainless steel nuts with a nylon insert, so they hold up in wet and outdoor locations where a plated steel nut would rust. Pair them with stainless bolts to avoid mixing metals.
3) Do these nuts meet Buy American requirements for a government or institutional job?
The JNYN173SS is flagged both ARRA compliant and Buy American compliant, which is what a public agency or school district spec usually asks for. Country of origin is listed as multiple.
4) How many 7/16-20 stainless locknuts come in a jar and can I buy less than a full jar?
They ship as a jar of 100, and 100 count is the order minimum, so a jar is the smallest buy. Jar weight is 2.08 lbs.
5) Will a nylon insert locknut hold on a vibrating load like a rooftop unit or motor mount?
That is what the nylon insert is for. The collar grips the bolt threads and resists backing off under vibration without needing a lock washer or thread locker. One limit worth knowing: the nylon is the locking element, so these are not meant to be reused many times or run on hot work where the insert can soften, and they are not a torque-bearing substitute for an all metal lock nut.
6) Do these Metallics locknuts match standard dimensions so they interchange with what is already on the job?
They are made to ASME B18.16.6, the dimensional standard for prevailing torque lock nuts, with B1.1 threads. That means they interchange with any other 7/16-20 UNF nylon insert locknut built to the same standard, so you can top off an existing fleet of fasteners without a mismatch.
7) How hard is the stainless on these locknuts, and will they gall on a stainless bolt?
Hardness is Rockwell B95 to C35. Stainless on stainless can gall if you run it up fast and dry, so thread them in slowly or use an anti-seize on the bolt.
