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.

Slotted Shim Assortments

When you don’t know the exact shim thickness you’ll need, keep multiple slotted shim thicknesses on hand so you always have the right one. 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.

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.

Painted 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.

Plastic—Softer than metal, these shims won't mar delicate surfaces and they will never rust.

Insertion Tools—Ease shim insertion and removal, keeping your fingers clear in the process.

Shims with Metal Case

Protect the shims from damage with the rugged metal case. Dividers sort the shims by thickness, while sturdy handles make it easy to carry them around.

Shims with Canvas Bag

Originally designed for climbing up wind turbines, swing these bags over your shoulder to tote shims while keeping your hands free. Attach the ring on the cover to your tool belt or a hook to keep the bags secure and open while you work. Dividers keep shims organized, while a hook-and-loop closure and clip keep them contained. These durable bags are high-visibility orange with a reflective stripe so you can’t miss them.
