DIN 126 is a standard that is widely recognized in the field of engineering and manufacturing. It provides specifications for washers, which are essential components used to distribute the load of a threaded fastener such as a bolt or a screw. These washers are designed to prevent damage to the surface of the material being fastened and to ensure a secure and reliable connection. The DIN 126 standard outlines the dimensions, materials, and tolerances for these washers, ensuring consistency and compatibility across different applications. By adhering to this standard, manufacturers can ensure that their products meet the necessary requirements for quality and performance.
