Shim Stock
Cut it into custom shapes to fit your application.
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. Metal shims include a material certificate with traceable lot number and test report.
Stainless steel shim stock is more corrosion resistant than steel shim stock.
Carbon steel shim stock has excellent strength and can be welded, but isn't as corrosion resistant as other shims.
Spring steel shim stock is comparable in strength to carbon steel shim stock, but is harder and holds its shape better. It isn't as corrosion resistant as other shims.
Brass, copper, and bronze shim stock is corrosion resistant and nonmagnetic.

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.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.

Triple-Wave Washers
With three points of surface contact, these washers provide more stability than single-wave washers. They are curved and flexible to act like springs, compensating for tolerance variations and uneven surfaces. You can also use them to damp vibration.
