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.Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.

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.

Shims for Keyed Shafts
Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.
Shims with a notch need the key inserted. They’re often referred to as arbor spacers.
Stainless steel shims are more corrosion resistant than carbon steel shims. Use them in wet environments where rust is a concern.

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.
Stainless steel shim stock is more corrosion resistant than steel shim stock. 316 stainless steel shim stock has the best corrosion resistance of our stainless steel shim stock.
Carbon steel shim stock has excellent strength and can be welded, but isn't as corrosion resistant as other shims.
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.
Aluminum shim stock is lightweight and nonmagnetic. It has good corrosion resistance. Material will vary between Alloys 1100, 1145, and 1235.
Brass, copper, and bronze shim stock is corrosion resistant and nonmagnetic. Copper shim stock is a good conductor of heat and electricity, so it's often used when installing heat sinks.
Titanium shim stock has a high strength-to-weight ratio and good corrosion resistance.

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.
316 stainless steel shim stock has high corrosion resistance. For precise leveling, 18-8 stainless steel shim stock is hard enough to resist scratching and deforming.
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. Aluminum shim stock is lighter than brass. 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.
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.

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.

Triple-Wave Washers
With three points of surface contact, these washers provide more stability than single-wave washers. They are curved and flexible to act like springs, compensating for tolerance variations and uneven surfaces. You can also use them to damp vibration.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
