Aluminum flat washer (pickled) / AAW
This product is a flat washer made of aluminum, which excels in lightweight and corrosion resistance, and has undergone acid washing treatment on its surface. It is used by being sandwiched between the fastening material and the bolt or screw during tightening. By distributing the load applied when tightening the screw over a wide area, it reduces the stress on the tightening surface, helps prevent dents and scratches on the counterpart material, and protects the seating surface. Additionally, using a flat washer stabilizes the fastening surface and supports the tightening condition of the bolt or screw. In addition to the excellent lightweight and workability unique to aluminum, the acid washing treatment removes surface dirt and impurities, smoothing the surface. It is suitable for a wide range of fastening applications that take advantage of aluminum's lightweight and corrosion resistance, starting from the assembly of various equipment and devices where weight reduction is required.
