This standard, EN 14399:2005, defines the criteria for high-strength structural bolted assemblies. It addresses a broad range of bolted connections used in engineering applications. The standard establishes guidelines for the design, production, inspection, and testing of bolted assemblies to ensure their safety. It also specifies the materials tha

DIN 931 specifies the standards for hex head bolts. These nuts are commonly used in numerous fields, from mechanical engineering tomanufacturing. The DIN 931 standard covers parameters such as diameter and thread pitch. It also defines requirements for material composition and tolerances. Adhering here to DIN 931 ensures robust connections and bo
