Superior Material & Finish for Demanding Environments
Forged from lightweight yet strong aluminum alloy, these metal washers undergo a meticulous anodizing process. This creates a hard, non-conductive oxide layer that provides exceptional corrosion resistance, making them ideal for use with oils and coolants. Unlike standard stainless steel washers, our anodized aluminum washers offer excellent sealing properties without galling and are non-magnetic. The dark blue color is not just for looks; it's a durable, integrated finish that won't chip or peel.
