High-strength structural bolting assemblies for preloading - Part 2: Suitability for preloading
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.
Hochfeste vorspannbare Garnituren für Schraubverbindungen im Metallbau - Teil 2: Eignung zum Vorspannen
Dieses Dokument legt die technischen Anforderungen an hochfeste Garnituren für Schraubverbindun¬gen im Metallbau fest, um deren Eignung für das Vorspannen von Schraubverbindungen in Metallkonstruktionen sicherzustellen.
Eine Eignungsprüfung wird festgelegt, um das Verhalten der Garnitur für Schraubverbindungen zu prüfen. Diese soll sicherstellen, dass die geforderte Vorspannkraft zuverlässig — mit ausreichend Reserven gegen übermäßiges Anziehen und gegen Versagen — mit den Anziehverfahren, die in EN 1090 2 festgelegt sind, erreicht werden kann.
Boulonnerie de construction métallique à haute résistance apte à la précontrainte - Partie 2: Aptitude à l'emploi pour la mise en précontrainte
La présente Norme européenne spécifie les exigences techniques pour la boulonnerie de construction métallique à haute résistance afin de vérifier l'aptitude à l'emploi pour la mise en précontrainte des assemblages boulonnés dans les structures métalliques.
Un essai d'aptitude à l'emploi est spécifié pour vérifier le comportement de la boulonnerie de construction de façon à s’assurer que la précontrainte requise peut être obtenue de façon fiable avec les méthodes de serrage spécifiées dans l'EN 1090-2, avec une marge de sécurité suffisante vis-à-vis du surserrage et de la rupture.

Overview
EN 14399-2:2015 - High-strength structural bolting assemblies for preloading - Part 2: Suitability for preloading (CEN) specifies the technical requirements and a suitability test to verify that high‑strength bolting assemblies can reliably achieve the required preload in metallic structures. The standard ensures bolted connections tightened using the methods in EN 1090‑2 reach intended bolt force with safe margins against overtightening and failure.
Key topics and technical requirements
- Suitability test: Defines test apparatus, test assemblies and procedures to evaluate assembly behaviour during tightening. Test outputs include rotation/bolt‑force, torque/bolt‑force and elongation/bolt‑force curves to assess performance.
- Preload criteria: Verifies that assemblies can obtain required preload (Fp,C) and defines evaluation metrics (individual and mean bolt forces, k‑factor, variation).
- Component composition and marking: Specifies allowed combinations (systems HR, HV, HRC), mandatory marking (manufacturer ID, system letter H and property class symbols) and the need to avoid mixing systems.
- Manufacturing and coatings: Requires compatible coatings under manufacturer control, attention to hydrogen embrittlement risks (especially for property class 10.9), rolled threads for 10.9 bolts, and that hot‑dip galvanized nuts be galvanized before threading. Nuts must not be re‑threaded.
- Delivery conditions: Bolting assemblies must be supplied in sealed packaging from one manufacturer (either complete sets or component packs) to preserve preloading suitability.
- Test reporting and quality control: Sets expectations for test reports and information to be supplied with products (tightening guidance per EN 1090‑2).
Applications
- Quality assurance for preloaded bolted connections in structural steel and metallic construction.
- Verification by manufacturers that bolt/nut/washer assemblies meet functional preload requirements before shipment.
- Use by fabricators, structural engineers and contractors to select assemblies that will perform reliably when tightened on site.
- Support for procurement, inspection and compliance checks during execution of steel structures.
Who uses this standard
- Bolt and fastener manufacturers (product design, marking, coating control)
- Structural steel fabricators and erectors (assembly selection and installation)
- Structural engineers and specification writers (design and compliance)
- Quality inspectors, testing laboratories and certification bodies
