This European Standard specifies, together with EN 14399- and EN 14399-2, the requirements for assemblies of high-strength structural bolts and nuts of system HRC suitable for preloaded joints, with hexagon head (large widths across flats), cup head or countersunk head, thread sizes M12 to M36 and property class 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; or

- nut with height m = 1 D;

- thread length of the bolt in accordance with ISO 888.

Bolting assemblies in accordance with this document include washers according to EN 14399-6 or to EN 14399-5 (under the nut only).

NOTE – Attention is drawn to the importance of ensuring that the bolting assemblies are correctly used if a satisfactory result is to be obtained. For recommendations concerning proper application, reference to EN 1090-2 is made.

General requirements and requirements for suitability for preloading are specified in EN 14399-2 and in Clause 8 of this document.
