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.

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.

Shims

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.

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.

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.

Best for filling large gaps, these thick shims are commonly used to align cabinets, doors, and windows. Slip them around existing mounting fasteners without unfastening them. All are made of plastic to resist moisture and prevent rot. To reduce sizing errors, these shims are color coded by thickness to quickly spot and grab the right size every time.

Secure-Stack Slotted Shims

Snap these shims together and they’ll stay securely stacked to maintain alignment. Best for filling large gaps, they're commonly used to align cabinets, doors, and windows. Slip them around existing mounting fasteners without unfastening them. To reduce sizing errors, these shims are color coded by thickness to quickly spot and grab the right size every time. All are made of plastic to resist moisture and prevent rot.
