Peel-Away Layered Ring Shims
These shims are made of layers of metal bonded with adhesive. Remove layers with a utility knife until you get the thickness you need. To make the layers easier to pull apart, gently heat the shim to soften the adhesive. These shims fit around fasteners and shafts to precisely align, level, and adjust spacing.
Aluminum and brass are softer than stainless steel, so they can be used as wear plates between components that rub together, preventing damage to equipment. Brass is more corrosion resistant than aluminum.
