A DIN 9021 flat washer, made from (Grade 4) Mild steel, is a large-diameter circular disc used to distribute the load of a fastener over a significantly larger area than a standard washer. Its primary purpose is to protect softer or thinner materials from damage and cover oversized holes in general engineering applications within moderate corrosion environments.
