DIN 7984 is a technical standard that outlines the specifications and requirements for cross-recessed screws with a hexalobular internal driving torque transmission. Published by the German Institute for Standardization (Deutsches Institut für Normung), this standard ensures that screws manufactured according to its guidelines meet specific dimensions, materials, and performance criteria. The DIN 7984 standard covers various aspects, including the design and geometry of the screw, its strength and durability, as well as its compatibility with corresponding driving tools. By adhering to these standards, manufacturers can guarantee the quality and reliability of their screws, thereby enhancing the overall performance and safety of the assemblies and structures in which they are used.
