    Wide-Rim Shims

    Image of Product. Front orientation. Shims. Wide Rim, Round, Sold Individually.
    Spread loads across a wider surface area than standard shims to minimize costly wear between components. 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.
    Zinc-Plated Carbon Steel—A common choice for areas with occasional exposure to moisture.

    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.

    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.
    Highly 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.
