Metallics WW82M – Frequently Asked Questions
1) What bolt size does the Metallics WW82M flat washer fit?
The WW82M is a 3/8 inch USS flat washer, so it pairs with 3/8 inch bolts, hex screws, and threaded rod. USS pattern means a larger outside diameter and bigger hole than the SAE pattern in the same nominal size, which is what you want when the washer has to spread load across sheet metal, strut, or a slightly oversized hole.
2) Are these Metallics washers zinc plated for damp or outdoor use?
Material is zinc plated steel. The zinc gives ordinary corrosion resistance for indoor electrical work, damp locations, and covered exterior runs. For direct weather exposure, salt air, or wet process areas, step up to a hot dip galvanized or stainless washer instead.
3) How many washers come in a box of Metallics WW82M?
One box holds 1,000 pieces of the 3/8 inch USS flat washer. The pack type is a box, and the shipping weight of that box is listed at 15.39 lbs, so it is a bulk quantity meant for a job box or a shop bin rather than a single fixture.
4) Can I use a 3/8 USS flat washer with 3/8 threaded rod for hanging strut and conduit?
Yes. A 3/8 inch USS flat washer is the standard bearing washer under a 3/8 inch rod nut for trapeze hangers, strut, and conduit supports. The wider USS outside diameter spreads the nut load over the strut slot or channel better than an SAE washer of the same size. Pair it with a nut, and add a lock washer or a nylon insert nut where vibration is a concern.
5) What part number do I order for Metallics 3/8 inch USS flat washers?
Order Metallics MPN WW82M. That is the single catalogue number covering the 3/8 inch USS flat zinc plated steel washer in the 1,000 piece box, so there is no finish or size option to specify.
