Shim Stock

Cut it into custom shapes to fit your application.
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. Metal shims include a material certificate with traceable lot number and test report.
Nickel shim stock is our most corrosion resistant shim stock.
