Made-to-Order Shims

Image of Product. Front orientation. Shims. Sold Individually, Made-to-Order.

If you need a unique shim shape or size, we’ll precision cut it for you. With thickness tolerances as fine as a strand of hair, these shims precisely align, space, and level components on shafts, arbors, and machinery.

You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.

Send your dimensioned DWG, DXF, IGES, or STEP file to sales@mcmaster.com. 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.

18-8 Stainless Steel—The choice for wet and outdoor environments, these shims resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these shims won't degrade when exposed to harsh weather, salt water, and most chemicals.

Carbon Steel—Best for dry environments since moisture will cause these shims to rust.

Brass—With a warm, polished look, these shims are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments.

Material Certificate—Shims include a report with a traceable lot number.

Peel-Away Multilayer Made-to-Order Shims

Image of Product. Front orientation. Shims. Multilayer, Sold Individually, Made-to-Order, Peel Away.

If you need a unique peel-away shim shape or size, we’ll precision cut it for you. Use these shims to fine-tune thickness without worrying about stacking multiple shims. They're made of metal layers bonded with adhesive—peel off the layers with a utility knife until you reach your desired thickness. To make peeling easier, warm the shims to soften the adhesive. With thickness tolerances as fine as a strand of hair, all of these shims precisely align, space, and level components on shafts, arbors, and machinery.

Send your dimensioned DWG, DXF, IGES, or STEP file to sales@mcmaster.com. Please leave at least _1/8" wall between shim edge and holes. Minimum hole size is _1/4". 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.

18-8 Stainless Steel—The choice for wet and outdoor environments, these shims resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.

Carbon Steel—Best for dry environments since moisture will cause these shims to rust.

Aluminum—These shims are an alternative to stainless steel for rust resistance but aren't as hard so they may not retain their shape as well. One-third the weight of steel, they’re commonly used in robotics and automation.

Brass—With a warm, polished look, these shims are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments.

Material Certificate—Shims include a report with a traceable lot number.
