Metallics JNYN165SS – Frequently Asked Questions
1) What thread size are the Metallics JNYN165SS nylon insert lock nuts?
They are 3/8-16 nuts, 16 threads per inch, cut to the ANSI/ASME B1.1 thread standard. The nut itself is built to ASME B18.16.6 for hex nylon insert lock nuts, so it mates with standard 3/8 inch bolts, rod, and studs of the same pitch.
2) Do these stainless locknuts qualify for a Buy American or ARRA funded project?
No. The JNYN165SS is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. If your contract carries a domestic sourcing clause, these will not satisfy it and you need a domestically produced 3/8-16 stainless nylon insert locknut instead.
3) Are these 3/8-16 locknuts stainless, and will they hold up outdoors?
The material is 18-8 stainless steel, the common austenitic grade used for general corrosion resistance in damp and outdoor service. Hardness runs Rockwell B95 to C35. The nylon insert is a thermoplastic locking element, so these are a mechanical fastener for ambient temperature service rather than a high heat application.
4) How many nuts come in a jar of Metallics JNYN165SS?
They ship 100 to a jar, and the jar is the minimum order unit. Jar weight is 1.81 lbs. Other sizes and quantities can be requested if 3/8-16 in 100-count is not what the job needs.
5) Will a 3/8-16 nylon insert locknut work for hanging strut and conduit trapeze?
Yes, that is the kind of work it is meant for. The field application calls out areas of high vibration along with electrical, plumbing, and heating and air conditioning service, which covers 3/8 inch hanger rod and strut hardware. Match it to 3/8-16 rod, 16 threads per inch, and keep in mind the nylon collar means you drive it down the rod rather than spinning it freely by hand the last few turns.
6) Can I reuse a nylon insert locknut after I take the joint apart?
Treat them as limited reuse. The locking action comes from the bolt cutting its own path through the nylon collar, so the grip drops off each time it is run on and off. On a vibration-critical connection, pull a fresh nut from the 100-count jar rather than reinstalling one that has already been torqued.
