DIN 931 refers to a specific standard for hexagon head bolts, which are widely used in various engineering and construction applications. This standard outlines the dimensions, mechanical properties, and material specifications necessary for ensuring the reliability and performance of these fasteners. Typically made from carbon steel or alloy steel, DIN 931 bolts are designed to provide high tensile strength and durability, making them suitable for heavy-duty applications. The standard also specifies the thread type, which is usually metric, and the surface finish, which can vary depending on the
