    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.
    Ultra-Chemical-Resistant PTFE—The most chemical-resistant shim stock we offer, it stands up to the widest range of harsh acids, bases, solvents, and corrosive cleaners, even at temperatures up to 500° F. It also won't mar delicate surfaces.

    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.
    Polyimide—Originally designed for military aircraft, it’s used in everything from aerospace to electronics where weight, electrical insulation, and precision are vital.

    Adhesive-Back Shim Stock

    Image of Product. Front orientation. Shim Stock. Adhesive-Back Shim Stock.
    Stick with confidence—a durable adhesive keeps this shim stock from sliding out of place. Cut the 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.
    18-8 Stainless Steel—The choice for wet and outdoor areas because it resists rust. However, it will corrode or pit when exposed to salt water and chemicals.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, it won't degrade when exposed to harsh weather, salt water, and most chemicals.
    Aluminum—An alternative to stainless steel for rust resistance but less hard so it may not retain its shape. One-third the weight of steel, it's often used in robotics and automation.
    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.
