This European Standard specifies the general requirements for bolt/nut/washer(s) assemblies for high-strength structural bolting, which are suitable for preloading. The intended use of bolting assemblies in accordance with this European Standard is structural metallic works. NOTE 1 High-strength structural bolting assemblies in accordance with EN 14399-2 to EN 14399-10 are designed to fulfil the requirements of this European Standard. NOTE 2 High-strength structural bolting assemblies are suitable for preloading in accordance with EN 1090-2 in steel structures. High-strength structural bolting assemblies smaller than M12 are not designed to be preloaded. High-strength structural bolting assemblies are not designed to be welded. Railway rail fasteners are not covered by this standard.
