Metallics MSCW381SS – Frequently Asked Questions
1) What size strut channel bolt does the Metallics MSCW381SS channel washer fit?
The MSCW381SS is a 3/8 inch channel washer, so it pairs with 3/8 inch channel bolts, hanger rod, or threaded studs running through strut channel. The square profile seats inside the channel slot and spreads the load across the channel lips rather than letting the nut dig into a single point.
2) Is this channel washer stainless, and will it hold up outdoors or near salt water?
It's 316 stainless steel, the marine grade of stainless, which is the one to use for coastal, wash-down, and chemical-exposure installs where 304 stainless or plain zinc-plated hardware pits. For dry indoor strut runs you don't need to pay for 316, but there's no penalty in using it.
3) How many washers come in a box of Metallics MSCW381SS?
They ship 100 pieces to the box, which is how electrical contractors buy them for a trapeze or strut hanger job where every rod drop takes a washer at each channel connection.
4) Do I need a channel washer or will a flat washer work in strut?
A flat round washer bridges a strut slot poorly and can roll into it under load. A channel washer like the 3/8 inch MSCW381SS is shaped to sit in the channel and bear on the formed lips, which is what keeps a nut from pulling through. Use the channel washer at any point where a 3/8 inch bolt or rod passes through strut; keep flat washers for solid surfaces.
5) Should I mix 316 stainless washers with galvanized strut and nuts?
You can, but galvanic corrosion is the trade-off: stainless in contact with zinc-coated steel in a wet or salty environment drives the zinc coating to sacrifice first. If you've specified the 316 stainless 3/8 channel washer because the location is corrosive, specify stainless channel, nuts, and rod to match rather than mixing metals.
