About EN 15048 Non-Preloaded Structural Bolt Assemblies (SB System)

EN 15048 Non-Preloaded Structural Bolt Assemblies (SB System) are structural bolt assemblys produced and tested to the exact requirements of the EN 15048 specification. Featuring a Hex Head with Nut configuration with Coarse Thread thread form, they are available in property classes 8.8 / 10.9 across a size range of M8 to M36. The EN 15048 standard governs dimensional tolerances, mechanical properties including tensile strength, proof load and hardness, as well as surface finish requirements to ensure dependable performance in Structural Steel and EN 1090 CE Marking applications worldwide.
Our EN 15048 Non-Preloaded Structural Bolt Assemblies (SB System) are cold-forged from certified bar stock, heat-treated where required, and thread-rolled to guarantee consistent fit and fatigue performance. Every batch is documented with an EN 10204 3.1 Mill Test Report covering chemical composition, mechanical test results and dimensional inspection. Available in zinc electroplated, hot-dip galvanised, Geomet, Dacromet and black oxide finishes to match corrosion-resistance requirements for Industrial Buildings, Bridges and General Construction applications. As a global exporter of EN 15048 fasteners, we consolidate orders with other standard-specification items into single shipments, backed by complete customs documentation for over 50 countries.
