DIN988 SS304 316 M3 To M170 Shim Steel Flat Washer
Specification
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.
Spring steel shims are comparable in strength to carbon steel shims, but are harder and hold their
shape better. They aren't as corrosion resistant as other shims.
