Metallics N165B – Frequently Asked Questions
1) What thread does the Metallics N165B hex nut take, and will it fit a 3/8 inch threaded rod?
The N165B is a 3/8-16 hex nut, 16 threads per inch, which is the standard UNC coarse thread for 3/8 inch rod and bolts. It threads onto 3/8-16 all-thread rod used for conduit trapeze, strut, and fixture hanging. It will not run on 3/8-24 fine-thread fasteners.
2) Is the Metallics N165B a Grade 2 nut, and is that strong enough for conduit and fixture hanging?
It is a Grade 2 steel nut with a hardness of Rockwell B68 to C32. Grade 2 is the general-purpose carbon steel class and is what is normally used for electrical support work, conduit trapeze, strut, and fixture hanging. For structural or high-tension connections calling out Grade 5 or Grade 8, specify a higher grade nut instead.
3) How many nuts come in a box of Metallics N165B, and can I buy a smaller quantity?
The N165B ships as a box of 2,500 nuts, and 2,500 is the order minimum, so it is a bulk pack for crews doing repeat conduit and fixture hanging rather than a counter pack. Metallics does make other sizes and quantities available by request if 2,500 is more than the job needs.
4) Does the Metallics N165B hex nut meet Buy American and ARRA requirements for a government or institutional job?
Yes, the N165B is flagged as both Buy American compliant and ARRA compliant, which is the pairing public-works, federal, and institutional specs usually call for on fasteners. Country of origin is listed as multiple.
5) Can the Metallics N165B zinc hex nut be used outdoors or in a wet location?
The N165B is carbon steel with a zinc plated finish. Zinc plating is a light sacrificial coating meant for dry indoor and protected use; it will corrode in standing water, washdown areas, or coastal exposure. For wet, outdoor, or corrosive locations go to a hot-dip galvanized or stainless 3/8-16 nut.
6) How thick is the Metallics N165B nut, and how much rod engagement do I need to leave?
Nut height is 0.320 to 0.337 inch, with a head height of 21/64 inch. That is the amount of rod that has to pass through the nut for full thread engagement, so leave at least that much thread protruding past your strut, channel, or fixture hanger, and a thread or two more if you want it visible past the face.
7) How much does a box of 2500 Metallics N165B hex nuts weigh?
A full box runs 37.93 lbs, with carton dimensions of 9 x 9 x 6.13 inches. Worth knowing if you are staging material on a lift or hand-carrying it up floors, since it is a dense small carton rather than a light one.
