DIN 6923 is a German standard that outlines the specifications for hexagon socket screws with a large cylindrical shaft. Published by the Deutsches Institut für Normung (DIN), this standard ensures that these screws meet specific requirements for design, materials, and performance. The standard covers screws with a nominal diameter range of 1.6 mm to 10 mm and a length of up to 100 mm. It also defines the technical delivery conditions, including the mechanical properties, surface finish, and corrosion resistance of the screws. By adhering to DIN 6923, manufacturers can guarantee that their hexagon socket screws meet the highest quality and reliability standards, making them suitable for a wide range of applications in industries such as automotive, aerospace, and construction.
