Built for demanding structural, mechanical, and engineering jobs, these high tensile hex head bolts deliver dependable clamping force and long-lasting performance where secure fastening matters most. Manufactured to recognised DIN 931 / DIN 933 standards, they’re designed for precision fit and consistent quality across a wide range of heavy-duty applications, including construction, automotive, plant, and industrial assembly.

With a high tensile strength classification (commonly 8.8, with 10.9 options in some ranges), these bolts are engineered to perform under high-stress conditions and help maintain joint integrity over time. A corrosion-resistant zinc plated finish supports durability and service life in everyday site and workshop environments.

Available in both partially threaded and fully threaded configurations (dependent on standard), they offer flexible fastening solutions to suit different material thicknesses and load distribution requirements—ideal for professional tradespeople, engineers, and maintenance teams who rely on robust metric fasteners for repeatable results.
