Carriage bolts feature a unique design with a squared shank that locks within the hole, preventing rotation and ensuring a secure fastening. These bolts comprise a cylindrical head with a square or hexagonal recess, intended to be driven by a wrench or socket. DIN 603 carriage bolts conform with the stringent standards set by the German Institute f
This standard, EN 14399:2005, defines the criteria for high-strength structural bolted assemblies. It covers a wide range of bolted connections used in engineering applications. The standard outlines procedures for the design, production, inspection, and testing of bolted assemblies to ensure their safety. It also specifies the components that can
DIN 931 defines the specifications for six-sided head screws. These nuts are widely employed in diverse fields, from structural engineering toconstruction. The DIN 931 standard covers parameters such as length and thread type. It also sets requirements for material composition and tolerances. Complying with DIN 931 ensures robust connections and
