Metallics JSW82 – Frequently Asked Questions
1) Are the Metallics JSW82 washers plated for corrosion resistance?
They are steel with a zinc finish, listed as zinc chromate. That is a general indoor and protected-location plating, fine for dry mechanical rooms, electrical rooms and interior steel framing. For wet, coastal or direct-exposure work, step up to hot dip galvanized or stainless washers instead.
2) What are 7/8 flat washers like the JSW82 actually used for?
Metal to metal connections. On electrical work that means bolted strut and channel assemblies, equipment and transformer mounting, bolted connections to structural steel, and anywhere a 7/8 bolt or nut needs its load spread over a wider bearing area so it does not pull through or gall the mating surface.
3) Is a flat washer like the JSW82 enough, or do I need a lock washer too?
A flat washer spreads the load, it does not resist loosening. The JSW82 is a plain flat washer, so on vibrating equipment or anything subject to movement pair it with a 7/8 split lock washer or a nylon insert locknut. For static bolted steel connections the flat washer alone under the nut is the normal practice.
4) How many washers come in a jar of Metallics JSW82?
Each jar holds 100 flat washers. The jar pack is the useful part for a service van or a shop crib, it keeps the 7/8 size separated from the rest of the fastener bin instead of loose in a bulk box.
5) How much does a jar of 100 Metallics 7/8 flat washers weigh?
5.7 lbs per jar. Worth knowing if you are specifying several sizes for a parts order or planning what rides on the truck, since 7/8 steel washers are heavy relative to their count.
