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 fub × As 1) according to EN 1993-1-8 (Eurocode 3) and to obtain ductility predominantly by deformation of the engaged thread. For this purpose the components have the following characteristics:
- nut height approximately 0,8 d;
- hexagon fit bolt with short thread length
____________________
1) fub is the nominal tensile strength (Rm) and As the nominal stress area of the bolt.
