Attention: The DIN 6914 standard has been officially withdrawn and replaced by the current specification DIN EN 14399-4:2015-04.
Technical overview of DIN 6914 bolts
DIN 6914 defines the structural requirements for high-strength bolts equipped with a hexagonal head with an increased wrench size. These hardware products, supplied by EV Group China, are designed for critical connections in metal structures where high load-bearing capacity and resistance to dynamic loads are essential.
Application features and performance characteristics
Bolts that comply with DIN 6914 requirements are characterized by increased strength and geometry optimized for use in heavy mechanical engineering and steel frame construction. The increased under-head area and “wrench size” allow for the application of significant tightening torques, ensuring reliable preload in fastening assemblies. EV Group China engineers recommend using these products as part of sets for high-strength connections (HV-sets), which provide the required level of rigidity for building structures.
