A DIN 7980 spring washer, made from spring steel, is a single-coil helical split lock washer with a square cross-section wire. Its primary purpose is to resist loosening from vibration by providing light spring tension and slight biting action into the mating surfaces. It is suitable for general engineering and indoor/moderate outdoor applications where good corrosion resistance is needed.
