CE Approved BS EN 15048 Bolting Assemblies Grade 8.8 BZP

When erecting structural steelwork, fastener selection is not just a matter of preference; it is a strict legal requirement. Our BS EN 15048 CE Certified Non-Preloaded Bolting Assemblies are engineered to eliminate risk and ensure your project is fully compliant with the Construction Products Regulation (CPR) 2013. This CE certification is a mandatory guarantee that these fasteners have undergone rigorous mechanical testing, strict quality control, and complete batch traceability. Designed specifically for non-preloaded joints where the shear strength of the bolt and the bearing capacity of the steel carry the structural load these assemblies provide engineers, fabricators, and building inspectors with total, documented peace of mind.

Time is a critical asset on any job site, and manually sourcing and matching individual fixing components is highly inefficient and risks certification compliance. To solve this, our assemblies are supplied as a complete, ready-to-install three-part kit across our entire size range (M12, M16, M20, and M24). Each kit features a fully threaded Grade 8.8 setscrew manufactured to EN ISO 4017, allowing you to clamp materials securely without the nut bottoming out on a smooth shank. Paired with this is a Grade 8 hexagonal nut (EN ISO 4032), precisely matched to the bolt's mechanical properties to maintain the CE certification. To finish the assembly, a Form A flat washer (EN ISO 7091) is included to effectively distribute the clamping load.

Beyond their precise dimensions and legal certifications, these fasteners deliver exceptional physical performance tailored to the scale of your project. Whether you are using the M12 for lighter bracing or the massive M24 for primary column connections, the high-tensile Grade 8.8 carbon steel provides the superior yield strength necessary to bear immense structural loads without shearing. To protect this high-strength core, every component in the assembly is finished with a Bright Zinc Plating (BZP). This chemical treatment provides a clean silver aesthetic while offering vital sacrificial corrosion resistance. Perfect for indoor structural frameworks, dry environments, or temporarily exposed applications, these fully certified assemblies are the ultimate choice for compliant construction.
