DIN metric refers to a set of standards developed by the Deutsches Institut für Normung (DIN), the German Institute for Standardization, which specify the dimensions, tolerances, and other technical requirements for metric fasteners, such as screws, bolts, and nuts. These standards ensure compatibility and interchangeability of parts in engineering and manufacturing applications across different industries.
