    Shim Stock Assortments

    When you don’t know the exact shim thickness you’ll need, keep shim stock in multiple thicknesses on hand so you always have the right one. Cut this shim stock into custom shapes to create shims that suit your needs. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, 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.

    Peel-Away Multilayer Shim Stock

    Image of ProductInUse. Front orientation. Shim Stock. Peel Away, Sold Individually, Multilayer.
    Fine-tune thickness without worrying about stacking multiple shims. Cut the shim stock into custom shapes that suit your needs. It's made of layers of material bonded with adhesive—peel off the layers with a utility knife until you reach your desired thickness. To make peeling easier, warm the created shims to soften the adhesive. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, and machinery.

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