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.

Belleville Spring Lock Washers for Socket Head Screws
These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws. Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Serrations on the top and bottom provide extra gripping power. Load-rated Belleville disc springs are also available.
Zinc-plated steel washers are corrosion resistant in wet environments.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
