Eaton B201ZN – Frequently Asked Questions

1) Will the Eaton B-Line B201ZN square washer fit 3/8" threaded rod?
Yes. The B201ZN is sized for 3/8 inch bolt or threaded rod, with a 7/16 inch diameter hole so the rod passes through with clearance rather than binding. If you are hanging strut or conduit trapeze off 3/8 inch all-thread, this is the matching washer size.
2) Why use a square washer instead of a round flat washer on strut channel?
Square washers spread the bolt load over a much larger footprint. This Eaton B-Line washer is 1.62 inches across, so it bears across the lips of channel and across slotted or oversized holes that a small round washer would pull through. Square edges also sit against the channel lip and resist spinning while you torque the nut.
3) Is the B201ZN washer okay for outdoor or damp electrical rooms?
The washer is steel with an electro-plated finish, which is a zinc-type plating suited to indoor and normally dry or occasionally damp locations. For sustained outdoor exposure, wash-down areas or coastal air, spec a hot-dip galvanized or stainless square washer instead, since electro-plating is a thin coating and will not hold up the same way.
4) Does the Eaton B-Line square washer carry any listing or certification?
No listing or certification applies to this washer. It is a plain steel fastening component, so if your job spec calls for a listed or certified assembly, that requirement lands on the channel, hanger or support system rather than on the washer itself.
5) Can I use this washer to mount a panel or enclosure to structural steel?
Yes, on 3/8 inch bolted connections. The 1.62 inch square face distributes clamping load across the mounting flange or an oversized drilled hole, which is the usual reason a square washer gets called out on enclosure and equipment mounting rather than a standard round washer.
