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.

18-8 stainless steel shim stock is more corrosion resistant than carbon steel shim stock.

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.

18-8 stainless steel shims are more corrosion resistant than carbon steel shims.

Peel-Away Layered Ring Shims

These 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. These shims fit around fasteners and shafts to precisely align, level, and adjust spacing.

For precise leveling, 18-8 stainless steel is hard enough to resist scratching and deforming.
