A DIN 127 B spring washer, made from A4 (Grade 316) "marine-grade" stainless steel, is a single-coil helical split lock washer. Its primary purpose is to resist loosening from vibration by providing light spring tension and slight biting action into the mating surfaces, offering superior corrosion resistance for use in harsh environments like marine, chemical processing, and coastal construction applications.
