    Shim Stock

    Image of Product. Front orientation. Shim Stock. Sold Individually.
    Cut 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.
    Brass—Picked for its warm, polished look. Similar to 18-8 stainless steel, it resists rusting in wet and outdoor areas.
    Temper Rating—Choose half hard to create shims that you’ll need to bend or shape. Opt for full hard to make stronger shims that will maintain their shape under loads.

    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.
    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.
