This European Standard specifies, together with EN 14399-1 and EN 14399-2, the requirements for assemblies of high-strength structural countersunk bolts and nuts of system HR suitable for preloaded joints with thread sizes M12 to M36 and property classes 8.8/8 or 8.8/10 and 10.9/10.
Bolting assemblies in accordance with this document have been designed to allow preloading of at least 0,7 fub × As according to EN 1993-1-8 (Eurocode 3) and to obtain ductility predominantly by plastic elongation of the bolt. For this purpose the components have the following characteristics:
- regular nut height according to style 1, see EN ISO 4032;
- thread length of the bolt according to ISO 888.
Bolting assemblies in accordance with this document include washers according to EN 14399-6 or to EN 14399-5.
