Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
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.
Stainless steel shims are more corrosion resistant than steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Aluminum shims are lightweight and nonmagnetic. They have good corrosion resistance.
Brass and copper shims are corrosion resistant and nonmagnetic. Copper shims are good conductors of heat and electricity, so these shims are often used when installing heat sinks.

Tight-Fit Ring Shims
For a snug fit around a shaft, the ID of these shims is held to a tighter tolerance than other ring shims.
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 alloy steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Brass shims are corrosion resistant and nonmagnetic.

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.
Spring steel shim stock is comparable in strength to carbon steel shim stock, but is harder and holds its shape better. It isn't as corrosion resistant as other shims.
Brass, copper, and bronze shim stock is corrosion resistant and nonmagnetic. Bronze shim stock is stronger than copper or brass shim stock.

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.
Aluminum shim stock is lightweight and nonmagnetic. It has good corrosion resistance.
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.
