Shim Stock

Cut it into custom shapes to fit your application.

Spring steel shim stock is comparable in strength to carbon steel shim stock, but is harder and holds its shape better. It isn't as corrosion resistant as other shims.

Adhesive-Back Shim Stock

A durable acrylic adhesive keeps this shim stock from sliding out of place. Cut it into custom shapes to fit your application. Shim stock is corrosion resistant. It includes a material certificate with traceable lot number and test report.

Aluminum and brass shim stock are softer than stainless steel, so they can be used as wear plates between components that rub together, preventing damage to equipment. Aluminum shim stock is lighter than brass.

Electrical-Insulating Cup Sleeve Washers

These nylon washers have a flat bottom and high walls to protect metal screw heads from electrical current and prevent galvanic corrosion from mating different types of metal. Exposure to moisture may cause them to expand.

Shims for Keyway Broaches

When broaching in multiple passes, shims are necessary to ensure full keyway depth. Slide them between the broach and bushing to set the depth of the keyway.

Note: Broaches have a style designation of A, B, B1, C, C1, D, D1, or E. For proper fit, broaches, bushings, and shims used together must have the same letter designation.
