Metallics N163B – Frequently Asked Questions
1) What thread size are the Metallics N163B hex nuts, and will they fit a 1/4-20 bolt or rod?
The Metallics N163B is a 1/4-20 hex nut, so 20 threads per inch on a 1/4 inch diameter. It threads onto standard 1/4-20 UNC bolts, machine screws and 1/4-20 threaded rod used for strut, hanger and box mounting work. It will not fit 1/4-28 fine thread hardware.
2) Are the Metallics N163B nuts strong enough for electrical strut and hanger rod work?
They are Grade 2 steel nuts with a hardness of Rockwell B68 to C32, which is the standard commercial grade for general electrical mounting, strut, box and fixture hanging. If your drawing calls out Grade 5 or Grade 8 nuts for a structural or high-load connection, specify those instead.
3) How many nuts come in a box of Metallics N163B, and can I buy a smaller quantity?
It ships as a box of 8,000 pieces, and 8,000 is the order minimum, so this is a shop or warehouse stocking quantity rather than a job box count. Other sizes and quantities are available by request.
4) What wrench or socket size do the N163B 1/4-20 nuts take?
Across the flats the nut measures 0.423 to 0.438 inch, which is a 7/16 inch wrench or socket. Corner to corner it runs 0.488 to 0.505 inch, so allow that clearance in tight channel or box work.
5) Is zinc plated steel okay for outdoor or damp locations?
The N163B nut is steel with a zinc finish. Zinc plating is a mild corrosion coating meant for dry interior and protected locations. For exterior, wet, coastal or washdown areas, go with stainless or hot dip galvanized nuts rather than zinc plated steel.
6) Do the Metallics N163B hex nuts meet Buy American or ARRA requirements for a public project?
The N163B is flagged Buy American compliant and ARRA compliant in the manufacturer's data, with country of origin listed as multiple. On a federally funded job, pull the mill or supplier certification for the specific lot you receive for your submittal package.
7) How heavy and how big is the box of 8,000 Metallics N163B nuts?
The carton weighs 55.9 lbs and measures 9 in by 9 in by 6.13 in. Plan on one person lifting it off a pallet, and account for the weight if you are shipping to a jobsite with no dock.
