DIN 127B spring washers, also known as spring lock washers or split washers, serve a crucial purpose in preventing nuts and bolts from loosening due to vibrations or external forces. These irregularly shaped washers are compressed and can return to their pre-deformed shape when subjected to load. Typically made from high-quality steel, they exert a spring force between the fastener head and the substrate, ensuring secure connections in various applications.
