Metallics JN166PL – Frequently Asked Questions
1) Will the Metallics JN166PL hex nut thread onto 1/2-13 all-thread rod?
Yes. The JN166PL is a 1/2-13 hex nut, 13 threads per inch, which is the standard UNC coarse pitch for 1/2 inch rod and bolts. It will run onto 1/2 inch all-thread, hanger rod, or 1/2-13 bolts. It will not fit 1/2-20 fine thread.
2) What grade and hardness are these Metallics 1/2-13 hex nuts?
Grade 2 steel, hardness Rockwell B68 to C32. Grade 2 is the general-purpose carbon steel class used for light to moderate load work like conduit hangers, strut, and equipment mounting. If your drawing calls for a Grade 5 or Grade 8 nut on a high-strength bolted joint, specify that instead.
3) Are these hex nuts plated or bare steel, and can I use them outdoors?
Finish is plain, uncoated steel. Bare carbon steel with no zinc or galvanized coating will rust in wet or outdoor locations, so for exterior, damp, or corrosive areas choose a zinc-plated or hot-dip galvanized 1/2-13 nut. Plain nuts are fine for dry interior electrical work.
4) What wrench or socket size fits the JN166PL 1/2-13 nut?
Across the flats it measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the fit. Nut height runs 0.427 to 0.448 inch.
5) Do these 1/2-13 nuts meet a dimensional standard for spec work?
They are built to ASME B18.2.2, the dimensional standard for inch-series hex nuts. That means the width across flats and the thickness fall within the standard envelope, so they interchange with any other B18.2.2 1/2-13 hex nut on the job.
6) How does the Metallics JN166PL ship, and what is the minimum I can order?
It ships in a jar of 50 count, and 50 is the order minimum, so you buy by the jar rather than the piece. The packed jar weighs 1.86 lbs.
7) Are Metallics JN166PL nuts Buy American and ARRA compliant for a government job?
The JN166PL is flagged compliant for both Buy American and ARRA. Country of origin is China, so if your contract requires domestic melt and manufacture rather than the broader compliance flag, confirm which standard the spec is written to.
8) I need 1/2-13 nuts in a different quantity or plated finish. Is that possible from the JN series?
Other sizes and quantities in the Metallics JN hex nut series are available by request. The JN166PL itself is the plain steel, 1/2-13, jar of 50 configuration.
