Tight-Fit Ring Shims
For a snug fit around a shaft, the ID of these shims is held to a tighter tolerance than other ring shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like brass, can be used as wear plates between components that rub together, preventing damage to equipment.
Stainless steel shims are more corrosion resistant than alloy steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Brass shims are corrosion resistant and nonmagnetic.

Adhesive-Back Shim Stock
A durable acrylic adhesive keeps this shim stock from sliding out of place. Cut it into custom shapes to fit your application. Shim stock is corrosion resistant. It includes a material certificate with traceable lot number and test report.
316 stainless steel shim stock has high corrosion resistance. For precise leveling, 18-8 stainless steel shim stock is hard enough to resist scratching and deforming.
Aluminum and brass shim stock are softer than stainless steel, so they can be used as wear plates between components that rub together, preventing damage to equipment. Brass shim stock is more corrosion resistant than aluminum.

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.
