Washers

You never think about washers until you run out of them, but they are vital for a dozen different applications. Ensure a tighter join with a lock washer, or pre-load it with a wave washer. Don't forget an insulating flat washer to prevent galvanic corrosion if you have steel screws on an aluminum surface, or a countersunk washer for that finished appearance. Stock up now on washers at Grainger.

Washers Technical Information


A washer is a relatively thin disk or square with a pre-drilled hole that is placed beneath a nut, an axle bearing, or a joint as a seat to support and distribute the load. Additional uses are as a spacer, wear pad, pre-load indicating device, or locking device. Some types provide spring tension. Depending upon material, washers also insulate, seal, or provide an electrical connection.

WASHER TYPES

Structural
Top-bearing surface is cut at an oblique angle to compensate for nonparallel surfaces in structural leveling and shimming applications. Round or square.
  MATERIALS

Brass—alloy of copper and zinc that resists rust and moderate atmospheric corrosion. Not high in strength, but is durable and conducts electricity. Often used for appearance. Nonmagnetic.
