| Subject of the standard: | This draft 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. NOTE Attention is drawn to the importance of ensuring that bolting assemblies are correctly used if satisfactory results are to be obtained. |
