DIN 127B refers to a specific standard within the DIN (Deutsches Institut für Normung) system, which is the German national organization for standardization. This particular standard delineates the specifications for split lock washers with a bent end, commonly used across a variety of engineering and manufacturing applications. The purpose of these washers is to prevent fastening components from loosening under vibration or dynamic loads by providing a spring force. The specifications outlined in DIN 127B include dimensions, material properties, and mechanical requirements, ensuring that components manufactured under this standard are consistent and reliable. By adhering to such standards, engineers and manufacturers can ensure compatibility and safety across components and systems, facilitating both domestic and international commerce in engineering and industrial products.
