    Shims

    Image of Product. Front orientation. Shims. Round, Sold Individually.
    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.
    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.

    Shims for Ball Bearing Outer Rings

    Image of Product. Front orientation. CrossSection, ZoomedIn view. Contains Annotated. Shims. For Ball Bearing Outer Rings, Sold Individually, Round.
    Boost bearing efficiency and lifespan. Often used on motor shafts, these shims evenly distribute the load between multiple bearings by creating space between their outer rings. This prevents excessive pressure on any single bearing, maintaining proper alignment for smooth operation and reduced wear.
    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.
    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.
    Super-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.
    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.

    Shims for Keyed Shafts

    With a notch or tab, these shims fit snugly on keyed shafts to align and space gears, sprockets, and bearings. On keyed arbors, they’re often used to accurately space saw blades and cutters.
    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.
    Notch

    Fit these shims around keyed shafts and arbors that have a key inserted. They’re often referred to as arbor spacers.

    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 1/4". 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.
    Super-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.
    Material Certificate—Shims include a report with a traceable lot number.

    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.
    Sheets—Shim stock comes in sheets that are flat packed.
    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.
    Super-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.
    High-Strength 17-7 PH Stainless Steel—Similar in strength to steel, it won’t rust in wet and outdoor areas but can’t withstand harsh chemicals like 316 stainless steel.
    Carbon Steel—Best for dry areas since moisture will cause it to rust.
    Stress-Resistant Spring Steel—Harder and holds its shape better than carbon steel. Use it for high-stress applications, such as leveling heavy machinery. It's best for dry areas since moisture will cause it to rust.
    Painted 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.
    Copper—A good conductor of heat, it’s often used to install heat sinks. As our softest metal, it prevents component damage but may not retain its shape as well as other metals.
    Titanium—Grade 2 titanium, 99% pure, is often used in chemical-processing plants for its resistance to strong acids and other harsh chemicals. It has a high strength-to-weight ratio.
    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.
    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.

    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.
    Sheets—Shim stock comes in sheets that are flat packed.
    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.
    Super-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.

    Wave Spring Lock Washers

    Image of Product. Front orientation. Lock Washers. Wave Washer, Spring Lock Washer.
    The wavy shape flexes like a spring to keep nuts and screws secure on slightly uneven surfaces. These washers add a small amount of tension to stop fasteners from backing out due to mild vibration. While they don't hold as well as other lock washers, they do grip slightly better than curved washers. They work best in electrical panels, light fixtures, and other light duty assemblies. Since these washers hold their shape when untightened, you can reuse them a handful of times without losing strength.
    Steel—Best for dry environments since moisture will cause these washers to rust.
    3 Wave—More points of contact than single-wave washers for a better grip.
