Metallics N166PLB – Frequently Asked Questions
1) What thread size is the Metallics N166PLB hex nut?
The N166PLB is a 1/2-13 hex nut, meaning a 1/2 inch nominal diameter with 13 threads per inch. That is the standard UNC coarse thread pitch for 1/2 inch, so it mates with 1/2-13 threaded rod, all-thread hanger rod, and 1/2 inch coarse-thread bolts. It will not run onto 1/2-20 fine thread.
2) Are these Metallics hex nuts plated or plain steel?
Plain steel, uncoated. The N166PLB is described as a plain steel hex nut, so there is no zinc or galvanized finish on it. For indoor dry electrical work (strut, hanger rod, panel mounting) that is normally fine, but for damp, outdoor, or corrosive locations you want a zinc-plated, hot-dip galvanized, or stainless nut instead.
3) Will the Metallics N166PLB work on 1/2 inch threaded rod for hanging electrical conduit and strut?
Yes. Standard 1/2 inch all-thread hanger rod is cut 1/2-13 coarse thread, which is exactly what this nut is, so it threads straight on for trapeze hangers, strut mounting, and rod-hung conduit racks. Pair it with a 1/2 inch flat washer where you are bearing against strut or sheet metal to spread the load.
4) How many nuts come in a box of Metallics N166PLB?
600 pieces per package. It is a bulk contractor pack rather than a small count box, which suits shops running 1/2 inch threaded rod on a repeat basis. If you only need a handful for one fixture hang, this is far more than the job calls for.
5) Do these nuts come with washers or lock washers included?
No. The N166PLB pack is hex nuts only, 600 of them. If your assembly needs flat washers, lock washers, or nylon-insert lock nuts to resist vibration loosening, those are separate line items on the order.
6) What part number do I order for a 1/2-13 plain steel hex nut from Metallics?
Metallics part number N166PLB. There is one configuration, the 1/2-13 plain steel hex nut in the 600 piece pack, so the model number is all you need to specify on the order.
