This part of this European standard specifies together with EN 14399-1 the requirements for assemblies of highstrength structural hexagon fit bolts and nuts of system HV suitable for preloaded joints with large widths across flats, thread sizes M12 to M36 and property classes 10.9/10. Assemblies of hexagon fit bolts with shaft diameter (d + 1 mm) and nuts according to this part of this European Standard have been designed to allow preloading of at least 0,7 fub × As 1) according to ENV 1993-1-1 (Eurocode 3) and to obtain ductility predominantly by deformation of the engaged thread. For this purpose the components have the following characteristics: ç nut height approximately 0,8 d; ç hexagon fit bolt with short thread length. Hexagon fit bolt and nut assemblies according to this part of this European standard include washers according to EN 14399-6. A test method for suitability for preloading is specified in EN 14399-2.
