Stainless SUS304 flat washer / UUW-H
This product is a flat washer made from the representative austenitic stainless steel "SUS304," which has excellent corrosion resistance and mechanical strength. It is used by inserting it between the bolt or screw and the counterpart material during tightening. By distributing the load 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. With its excellent corrosion resistance and mechanical strength unique to SUS304, this flat washer is suitable for a wide range of fastening applications that prioritize corrosion resistance, such as various equipment and facilities in humid environments or where rust prevention is required.
