helical spring washers (grower)
DIN 128, UNI 8839 curved spring washers (growers) are designed to increase the safety of fastenings by preventing screws and nuts from loosening under vibration or mechanical stress. Their spiral shape allows constant spring pressure to be exerted, improving assembly stability. Available in variants type A (with overlapping ends) and type B (with separate ends), these washers are suitable for different fastening configurations. Made of carbon steel and A2 and A4 stainless steel, UNI 8839 grower washers are used in the industrial, mechanical and automotive sectors, guaranteeing reliability even under high stress conditions. We offer a wide selection of spiral spring washers conforming to DIN and UNI standards, ensuring high quality and performance.
