DIN 127B is a standard that specifies the requirements for spring lock washers. These washers are designed to provide a secure and reliable fastening solution by preventing loosening or rotation of the bolt or nut. The DIN 127B standard ensures that these washers have specific dimensions and characteristics, such as a helical shape and a slight conical form, which allow them to exert a constant spring force when compressed. This force helps to maintain the integrity of the fastened joint, even under vibrations or dynamic loads. By adhering to the DIN 127B standard, manufacturers can ensure the consistent quality and performance of these essential components in various industrial applications.
