Arbor shims are a type of flat washer that can be used for spacing and positioning other objects. Unlike regular washers, shims are constructed from non-ferrous materials such as low carbon steel. Metal shims also have no keyways that provide ease as a spacer part. Our steel shims have different dimensions and come in packs to best supply your applications. If you need additional shim materials, we carry shim stock that consists of shims rolls and more, as well as our shim stock assortments that provide slotted shim kits. We also have aluminum sheets and alloy steel sheets for various construction, manufacturing, and electrical projects.
