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.
Brass and copper shims are corrosion resistant and nonmagnetic. Copper shims are good conductors of heat and electricity, so these shims are often used when installing heat sinks.

Shims for Keyed Shafts
Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.
Shims with a notch need the key inserted. They’re often referred to as arbor spacers.
Stainless steel shims are more corrosion resistant than carbon steel shims. Use them in wet environments where rust is a concern.

Sleeve Washers for Soft Material
Reinforce holes in soft material to keep them from collapsing around screws.
Black-oxide steel washers have a corrosion-resistant exterior that's good for mostly dry environments.
