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 and test report.
Brass, copper, and bronze shim stock is corrosion resistant and nonmagnetic.

Adhesive-Back Shim Stock
A durable acrylic adhesive keeps this shim stock from sliding out of place. Cut it into custom shapes to fit your application. Shim stock is corrosion resistant. It includes a material certificate with traceable lot number and test report.
Aluminum and brass shim stock are softer than stainless steel, so they can be used as wear plates between components that rub together, preventing damage to equipment. Brass shim stock is more corrosion resistant than aluminum.

Peel-Away Layered Shim Stock
Cut this shim stock it into custom shapes to fit your application. Stock is made of layers of material bonded with adhesive; remove layers with a utility knife until you get the thickness you need. To make the layers easier to pull apart, gently heat the shim to soften the adhesive.
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.
Brass 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.
Brass shims are corrosion resistant and nonmagnetic.

Made-to-Order Peel-Away Layered 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 are made of layers of metal bonded with adhesive; remove layers with a utility knife until you get the thickness you need. To make the layers easier to pull apart, gently heat the shim to soften the adhesive. 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 or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Brass shims are corrosion resistant and nonmagnetic.
