Metallics JCN165 – Frequently Asked Questions
1) What thread size does the Metallics JCN165 cap nut fit?
The JCN165 acorn cap nut is a 3/8-16 nut, so it threads onto 3/8 inch bolts or rod with 16 threads per inch (standard 3/8 UNC coarse thread). It will not run onto 3/8-24 fine thread rod.
2) Can I use these cap nuts on a Buy American or ARRA funded job?
No. The JCN165 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project has domestic sourcing requirements, these will not satisfy them.
3) What is a cap nut used for on an electrical or mechanical install?
It covers the exposed threaded end of a bolt or hanger rod so nobody catches a hand or a sleeve on sharp threads, and it finishes the look on visible work. The JCN165 is specified for electrical, plumbing, and heating and air conditioning work, which is where exposed rod ends and bolt tails are most common.
4) Will a 9/16 wrench fit the Metallics JCN165 cap nut, or do I need a bigger one?
No. Across the flats the JCN165 measures 0.607 to 0.625 inch, which is a 5/8 inch wrench or socket. A 9/16 will not go on.
5) Is the JCN165 cap nut stainless, or plated steel?
Plated steel, not stainless. The body is steel with a nickel plated finish, which gives it a bright appearance for exposed work. For wet or corrosive locations you want a true stainless acorn nut instead.
6) How are Metallics JCN165 cap nuts packaged, and what is the minimum I can buy?
They come 100 to a jar, and the jar is the minimum order unit, so one purchase gets you 100 nuts. A filled jar weighs 1.88 lbs. Handy for a van or a shop bin rather than loose counts.
7) I need 1/2-13 acorn nuts instead of 3/8-16. Does Metallics make other sizes in the JCN series?
Yes, the JCN cap nut series is offered in other sizes and quantities by request; JCN165 is the 3/8-16 jar of 100. Tell us the thread size and count you need and we can source the matching JCN part.
