Slotted Shims

The slot lets you insert, remove, and adjust the shims without disassembling your machinery, while the tab keeps fingers and tools away from machine feet. Use an insertion tool (sold separately) for better leverage and reach. Shims are etched with the thickness.
18-8 stainless steel shims have a balance of strength and corrosion resistance.

Multi-Slotted Shims




Use a single shim on feet or positioning arms that are secured with multiple fasteners. The slots let you insert, remove, and adjust the shims without disassembling your machinery. Shims are made of steel for good strength. Also known as finger shims.

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.
Stainless steel shim stock is more corrosion resistant than steel shim stock.
Carbon steel shim stock has excellent strength and can be welded, but isn't as corrosion resistant as other shims.
