B-LINE B202ZN – Frequently Asked Questions

1) Is the electro-plated finish on the B202ZN washer OK for outdoor or wet locations?
Electro-plated zinc on steel is a light protective coating meant for dry indoor and protected commercial or industrial spaces. It handles condensation and normal humidity in a mechanical room or above a ceiling. For a roof curb, an exposed parking structure, a wash-down area, or anywhere salt or standing water is in play, spec hot-dip galvanized or stainless strut hardware instead. Mixing a plated steel washer into an otherwise stainless or galvanized assembly outdoors also invites galvanic corrosion at the joint.
2) How big is the bearing surface on the B-Line B202ZN square washer?
It measures 1.62 x 1.62 inches square, so you get roughly 2.6 square inches of bearing face minus the hole. That is the point of a square washer over a round flat washer at this size: far more surface spreading the clamp load, which is what keeps a bolt head or nut from pulling through channel slots, wood blocking, or thin sheet. Each piece weighs .17 lb, so a box of them adds up fast on a large order.
3) Why use a square washer instead of a round flat washer on strut channel?
Two reasons, and both matter on channel. The square corners of the 1.62 inch B202ZN body sit across the open lips of the strut rather than dropping into the slot, so the load transfers into the channel edges instead of trying to spread them. And the flat sides catch against adjacent framing or the channel throat, which keeps the washer from spinning while you run the nut up. A round washer of the same nominal size does neither reliably.
4) Does the B-Line B202ZN square washer come with a bolt or nut?
No. The B202ZN ships as the washer alone. You supply the 1/2 inch bolt or threaded rod, and on strut you also need a matching 1/2-13 channel nut or spring nut sized for the channel you are mounting into. Order those separately when you build out the assembly.
5) Can I use the B202ZN square washer for something other than strut, like bolting through wood or steel?
Yes. It is a general steel bearing washer with a 9/16 inch hole, so it works anywhere a 1/2 inch bolt needs its load spread: through wood blocking, timber framing, sheet steel, or a bracket with an oversized hole. The 1.62 inch square footprint is what does the work there, holding the head from crushing into or pulling through the softer material. It comes out of the strut fitting line but nothing about it limits it to channel.
