Metallics JCN164 – Frequently Asked Questions
1) Will the Metallics JCN164 cap nut thread onto a 5/16-18 bolt?
Yes. The JCN164 is a 5/16-18 cap nut, 18 threads per inch, so it threads onto standard 5/16 inch UNC rod or bolt. It is a closed (acorn) nut, so it covers the bolt end rather than letting thread run through.
2) Do these cap nuts meet Buy American or ARRA requirements on a federal job?
No. The JCN164 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries a domestic sourcing clause, this part will not satisfy it.
3) How much projecting bolt thread can an acorn cap nut cover?
Not much. The JCN164 stands only 0.365 to 0.385 inch tall overall, and the closed dome eats part of that, so it suits bolt ends that stop flush or project no more than a short stub. If your 5/16 inch rod sticks out further, cut it back or use a longer closed-end cap before trying to dress the end.
4) How are Metallics JCN164 cap nuts packaged and what is the minimum order?
They ship in a jar of 100, and 100 (one jar) is the minimum order quantity. Jar weight is 1.42 lbs. Metallics lists other sizes and quantities of cap nuts on request if 5/16-18 by the jar is not what you need.
5) Is the JCN164 a stainless steel acorn nut?
No. The JCN164 is nickel plated steel, not stainless. The plating gives the bright appearance, but the base metal is carbon steel, so for washdown, coastal, or chemically aggressive locations specify a stainless acorn nut instead.
6) Can a cap nut be used as the load-carrying nut on a threaded rod hanger?
Treat it as a finish and protection piece, not a structural nut. A closed acorn nut only engages the threads inside the dome, and the JCN164 is just 0.365 to 0.385 inch tall overall, so run a standard hex nut for the load and add the cap nut to dress and cover the exposed thread end.
