B-LINE N778ZN – Frequently Asked Questions
1) What thread size does the B-Line N778ZN channel nut take?
The N778ZN takes 5/8"-11 threaded rod or bolts. That is the coarse UNC thread, so standard 5/8 inch all-thread rod threads straight into it with no adapter.
2) Is this a spring nut or a plain channel nut?
It is a standard nut, meaning no spring. You slide it into the strut, turn it a quarter turn so the grooved ends bite the channel lips, then hold it in place while you start the rod. A spring nut is the one that stays put on its own during overhead work.
3) Will the N778ZN fit standard 1-5/8 inch strut channel?
Yes. At 1.375 in wide it drops between the inturned lips of standard 1-5/8 inch strut and turns a quarter turn to lock. The 1.875 in length is the dimension that spans the channel once it is rotated.
4) Is the electro-plated zinc finish on this B-Line nut suitable for outdoor or wet locations?
Electro-plated zinc on steel is an indoor, dry-location finish. It handles normal interior mechanical room and ceiling-space humidity, but for exterior runs, parking structures, or washdown areas you want hot-dip galvanized or stainless channel hardware instead.
5) Do I need anything else besides this nut to hang threaded rod from strut?
The nut is supplied on its own. You still need the 5/8"-11 all-thread rod itself, and if you are terminating a bolted connection rather than rod, the 5/8 inch bolt plus a flat washer. No spring, cone, or retaining clip comes with a standard nut.
6) What is the exact part number to order this 5/8 inch B-Line channel nut?
Order Eaton B-Line part N778ZN. The N778 is the tall channel nut body in 5/8"-11, and the ZN suffix is the electro-plated zinc finish.
7) Is this channel nut UL listed or certified for anything?
No listing or certification applies to the N778ZN. It is a plain steel mechanical channel nut, so specify it against the strut and rod schedule on your drawings rather than against a listing mark.
