Product：High-strength structural bolting assemblies for preloading

This standard on structural bolting reflects the situation in Europe where two technical solutions exist to achieve the necessary ductility of bolt/nut/washer assemblies. These solutions utilize different systems(HR and HV) of bolt/nut/washer assemblies. It is importance for the performance of the assembly to avoid mixing up the components of both systems. Therefore the bolts and nuts for both systems are standardized in one single part of this European Standard each and the marking of the components of the same system is uniform.
