Eaton TN224ZN – Frequently Asked Questions

1) Will an Eaton B-Line Twirl-Nut channel nut take 3/8 inch threaded rod?
Yes. The Twirl-Nut is tapped 3/8"-16, so it mates with standard 3/8 inch coarse-thread rod or bolts. If your trapeze hangers or panel mounts are run on 1/2"-13 or 1/4"-20 rod, this nut won't thread on and you need the matching thread size instead.
2) What is the difference between the TN224ZN and TN228ZN Twirl-Nut channel nuts?
Load rating. The TN224ZN carries a 300 lbs pull-out and slip rating; the TN228ZN carries 800 lbs. Both are the same 3/8"-16 steel Twirl-Nut. Pick by the load on the hanger, not by the rod, since the thread is identical between them.
3) Do I need a spring with the Eaton Twirl-Nut, or does it hold itself in the strut?
No spring. The Twirl-Nut is a spring-free design: you drop it into the channel slot and twirl it a quarter turn so the grooved ends bite the inturned lips of the strut, and it stays put while you start the rod. That's the point of the design versus a conventional spring nut, and it means one less loose part overhead on a lift.
4) Are Eaton Twirl-Nut channel nuts sold individually or in a box?
They ship 100 to a pack. That's the quantity to plan on for a panel-mounting or HVAC hanger job rather than counting out singles, and it's worth knowing before you order for a two-hanger repair.
5) Is the electro-plated zinc finish on the Eaton Twirl-Nut good enough for a damp or outdoor location?
Electro-plated zinc on steel is a dry-interior and protected-location finish. It handles normal indoor mechanical rooms, ceiling spaces, and electrical rooms. For wash-down areas, exterior runs, coastal air, or anywhere the strut assembly gets wet regularly, step up to hot-dip galvanized or stainless channel nuts instead, and match the strut finish so you aren't putting dissimilar metals together.
6) Can I use a Twirl-Nut to hang conduit and cable tray from strut?
Yes, that's the normal use. The nut anchors into the strut channel and gives you a 3/8"-16 tapped point for rod, conduit clamps, pipe straps, or tray hangers. It's the mounting hardware for electrical panels, HVAC equipment supports, and telecom racking on strut. What it does not do is provide the clamp itself, so order the conduit clamps or strut straps separately.
7) Do I need to weld or drill the strut to install a Twirl-Nut channel nut?
No drilling, no welding. The nut inserts anywhere along the open slot of the channel and turns to lock, so you set the position by sliding it, not by making a hole. That's what makes strut worth using: the mounting point can be moved later when the panel or duct run changes without leaving a hole in the steel.
