These high tensile bolts are engineered for strength, reliability, and long-term performance in demanding industrial, mechanical, and structural applications. Manufactured to internationally recognised standards, including DIN 931, DIN 933, DIN 960 and ISO 4014, they deliver excellent load-bearing capacity and consistent, repeatable clamping forces across a wide range of assemblies.

Available in performance classes 8.8, 10.9, and 12.9, these bolts offer superior resistance to stress, fatigue, and wear, making them suitable for heavy-duty engineering projects, plant and machinery maintenance, construction, fabrication, and automotive or agricultural equipment. The precision-rolled thread forms help ensure secure engagement, reduced risk of loosening under vibration, and easier installation with standard tools.

A choice of self-coloured (S/COL) or zinc-plated (Z/P) finishes provides durable protection in harsh operating environments. The self-coloured option is ideal for applications where subsequent coating, welding, or finishing may be required, while the zinc-plated option offers enhanced corrosion resistance for exposed or outdoor use.

Designed as part of a comprehensive metric fastening range, these bolts integrate seamlessly with compatible nuts, washers, and structural components. Whether used in new builds, repairs, or upgrades, they provide a dependable fastening solution where safety, precision, and high tensile strength are critical.

Choose these high tensile metric bolts when you need robust, standards-compliant fasteners that combine excellent mechanical performance with dependable durability in both general engineering and specialist applications.
