    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.
    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.
    Stress-Resistant Spring Steel—These shims are harder and hold their shape better than carbon steel. Use them for high-stress applications, such as leveling heavy machinery. They're best for dry environments since moisture will cause them 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.
    Copper—Good conductors of heat, these shims are often used when installing heat sinks. As our softest metal shims, they prevent damage to equipment and components but may not retain their shape as well as other metal shims.
    Ultra-Chemical-Resistant PTFE—The most chemical-resistant shims we offer, these stand up to the widest range of harsh acids, bases, solvents, and corrosive cleaners, even at temperatures up to 500° F. They also won't mar delicate surfaces.

    Slip these shims around existing mounting fasteners to precisely align and level components such as pumps, compressors, and gearboxes with motors, all without disassembling them. They’re also good for leveling machines on uneven surfaces. To reduce sizing errors, these shims are either labeled with their thickness so there's no need to measure or color coded by thickness to quickly spot the right size.
    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.
    Insertion Tools—Ease shim insertion and removal, keeping your fingers clear in the process.

    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.
    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.
    Carbon Steel—Best for dry areas since moisture will cause it to rust.
    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.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these washers won't rust when exposed to moisture. However, they can't hold up to the harsh chemicals that 316 stainless steel can.
    3 Wave—More points of contact than single-wave washers for a better grip.
