Shim Stock
Cut it into custom shapes to fit your application. Sheets come flat packed.
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. Most shims include a 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.
Brass, copper, and bronze shim stock is corrosion resistant and nonmagnetic.

Made-to-Order Shims
For unique shim shapes or sizes, send a dimensioned STEP or DXF file to chi.sales@mcmaster.com and we’ll precision cut your shim. Shims include a material certificate with traceable lot number and test report.
Please leave at least 1/8" wall between shim edge and holes. Minimum hole size is 1/8". Shims should be no smaller than 1" × 1" square or 1" OD. Maximum shim dimension is the largest overall length, width, or diameter of your custom shim.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like brass, can be used as wear plates between components that rub together, preventing damage to equipment.
Stainless steel shims are more corrosion resistant than carbon steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Carbon steel shims have excellent strength and can be welded, but they aren't as corrosion resistant as other shims.
