Aluminum flat washer (black anodized) / AAW-B
This product is a flat washer made of aluminum, which excels in lightweight and corrosion resistance, and has been treated with black anodizing on the surface. It is used by inserting it between the bolt or screw and the mating material during tightening. By distributing the load when tightening screws over a wide area, it helps reduce the stress on the tightening surface, suppresses dents and scratches on the mating material, and protects the seating surface. Additionally, using a flat washer stabilizes the fastening surface and supports the tightening condition of the bolts and screws. In addition to the excellent lightweight properties unique to aluminum, it contributes to improved corrosion and wear resistance due to the black anodizing treatment, resulting in a calm black appearance that reduces light reflection. This flat washer is suitable for the assembly of various equipment and devices where both lightweight and aesthetic design are required.
