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.
Carbon steel shim stock has excellent strength and can be welded, but isn't as corrosion resistant as other shim stock.
Brass shim stock is corrosion resistant and nonmagnetic.
Polyimide plastic shim stock is corrosion resistant, electrically insulating, and holds its shape at extreme temperatures. It's easier to peel apart than metal shim stock. Stock includes a material certificate with traceable lot number and test report.

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.
Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.
Aluminum shims are lightweight and nonmagnetic. They have good corrosion resistance.
Brass shims are corrosion resistant and nonmagnetic.
