Metallics SW74M – Frequently Asked Questions
1) Are the SW74M washers zinc plated for damp or outdoor electrical work?
They are steel with a zinc finish, which gives basic corrosion resistance for indoor and dry or lightly damp locations. Zinc plated steel is not the choice for sustained outdoor exposure, washdown, or coastal work; for that, specify stainless.
2) How many washers come in a box of Metallics SW74M?
One box holds 1,000 of the 5/16 inch flat washers, packaged as a box rather than loose or bagged count. That bulk count suits MRO cribs, panel shops, and contractors doing repetitive strut, hanger, and conduit support work where washers get consumed by the handful.
3) Can I use a 5/16 flat washer with 5/16 threaded rod for conduit and strut hanging?
Yes. A 5/16 flat washer like the SW74M seats under the nut on 5/16 inch rod or bolt to spread bearing load across strut, channel, or sheet metal and keep the nut from pulling through an oversized hole. Pair it with a 5/16 nut; for spring resistance or vibration you would add a lock washer or locknut, which is a separate item.
4) Is the Metallics SW74M a flat washer or a lock washer?
It is a flat washer, plain and unsplit, in 5/16 inch zinc plated steel. If you need the fastener to resist loosening under vibration, a split lock washer or a serrated flange nut is the right part instead, since a flat washer only spreads load.
5) Are Metallics SW74M washers made to ANSI dimensions?
Yes, the 5/16 flat washer is an ANSI dimensional item, so it interchanges with other ANSI standard 5/16 flat washers in your stock rather than being a proprietary size.
