Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Stainless steel shims are more corrosion resistant than steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.

Wide-Rim Ring Shims
Also known as machinery bushings, these shims have an oversized OD to create a larger bearing surface for reduced wear between moving parts. Use them to precisely align, level, and adjust spacing on shafts and machinery.
Stainless steel shims are more corrosion resistant than carbon steel shims.
Carbon steel shims have excellent strength and can be welded.
A zinc-plated finish adds a layer of corrosion resistance.

Slotted Shims
The slot lets you insert, remove, and adjust the shims without disassembling your machinery, while the tab keeps fingers and tools away from machine feet. Use an insertion tool (sold separately) for better leverage and reach. Shims are etched with the thickness.
18-8 stainless steel shims have a balance of strength and corrosion resistance.
