Description
EN14399-4 HV Carbon Steel Hex Bolt M16 - M36
EN 14399-4 High-Strength Structural Bolting Assemblies - System HV, Carbon Steel, Hexagon Bolt is a high-strength structural bolting assembly manufactured to EN 14399-4 for System HV, specifically designed for preloaded joints in steel structures. The assembly comprises a property class 10.9 hexagon head bolt, a property class 10 hexagon nut, and two hardened washers to EN 14399-6. Available in thread sizes M12 to M36, the bolt features a short thread length and large width across flats, engineered to achieve ductility through plastic deformation of engaged threads under preloading.

Mechanical Property Requirements for System HV Components
The bolt conforms to property class 10.9 per EN ISO 898-1, requiring minimum tensile strength of 1000 MPa and yield strength of 900 MPa. The mating nut is property class 10 to EN ISO 898-2, with proof load stress matching the bolt's tensile capacity. Washers are through-hardened to 300-370 HV hardness per EN 14399-6 to withstand clamping forces without embedment.
Short Thread Length Design and Preloading Performance
The bolt features a deliberately short thread length (typically with thread run-out before full shank diameter), ensuring that plastic deformation under preload occurs predominantly in the engaged threads rather than the bolt shank. This design achieves the required ductility for preloading of at least 0.7 fub * As (70% of ultimate tensile load) as specified in EN 1993-1-8 (Eurocode 3), while maintaining consistent clamp force in structural connections.
Assembly and Coating Requirements for EN 14399-4 Compliance
The assembly must include two washers per EN 14399-6 (one under bolt head, one under nut) to distribute preload forces. For hot-dip galvanized versions, threads are manufactured with 6az tolerance before coating per ISO 965-5, and nuts receive molybdenum disulphide lubricant (characteristic black appearance) to achieve consistent torque-tension relationships during preloading. All components must bear CE marking and traceability codes per hEN 14399-4, with batch-specific 3.1 inspection certificates.
