| Resumen: | This document belongs to the suite of European Standards EN 14399 and is designed to be read in conjunction with EN 14399-1 for: - general requirements; - testing for conformity evaluation; - evaluation of conformity; - regulatory marking; for assemblies of high-strength structural fit bolts and nuts of system HV suitable for preloaded joints with thread sizes M12 to M36 and bolt property class 10.9 and EN 14399-2 for suitability testing. This part gives requirements for: - dimensions; - associated washer(s) according to EN 14399-6; - performance and suitability tests; for assemblies with thread sizes M12 to M36 and bolt property class 10.9. 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 f<(Index)ub> × A<(Index)s> according to EN 1993-1-8 (Eurocode 3) and to obtain ductility predominantly by deformation of the engaged thread (f<(Index)ub> is the nominal tensile strength (R<(Index)m>) and A<(Index)s> the nominal stress area of the bolt). For this purpose the components have the following characteristics: - nut height approximately 0,8 d; - hexagon fit bolt with short thread length |
