Detailed Information

This document specifies together with EN 14399-1 the requirements for assemblies of high-strength structural bolts and nuts of system HV suitable for preloaded joints with large widths across flats, thread sizes M 12 to M 36 and property classes 10.9/10.

Bolt and nut assemblies to this document have been designed to allow preloading of at least 0,7 fub×As according to ENV 1993-1-1 (Eurocode 3) and to obtain ductility predominantly by plastic deformation of the engaged threads. For this purpose the components have the following characteristics:
– nut height approximately 0,8 d
– bolt with short thread length
Bolt and nut assemblies according to this document include washers according to EN 14399-6 or to EN 14399-5 (under the nut only).
