BS EN 14399-2:2015

This standard BS EN 14399-2:2015 High-strength structural bolting assemblies for preloading is classified in these ICS categories:

• 21.060.01 Fasteners in general

This European Standard specifies the technical requirements for high-strength structural bolting assemblies in order to ensure the suitability for preloading of bolted connections in metallic structures.

A suitability test is specified to check the behaviour of the structural bolting assemblies so as to ensure that the required preload can be reliably obtained by the tightening methods specified in EN 1090‑2 with sufficient margins against overtightening and against failure.
