Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.

Belleville Spring Lock Washers for Socket Head Screws
These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws. Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Serrations on the top and bottom provide extra gripping power. Load-rated Belleville disc springs are also available.

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.
