This document, EN 14399:2005, defines the criteria for high-strength structural bolted assemblies. It addresses a broad range of bolted joints used in engineering applications. The standard provides guidelines for the design, fabrication, inspection, and testing of bolted assemblies to ensure their reliability. It also specifies the elements that c

DIN 931 specifies the requirements for six-sided head screws. These bolts are widely employed in diverse applications, from structural engineering toconstruction. The DIN 931 standard covers sizes such as diameter and thread pitch. It also sets requirements for material quality and precision. Adhering to DIN 931 ensures robust connections and boo
