China ANSI D-21 Manufacturer, Supplier, Factory

China's economy underwent a major shift in September 2024, resulting in high volatility in the price of steel raw materials, resulting in our prices changing daily, as we need to order raw material production in real time, our offer validity period is shortened, our prices follow the changes in Chinese steel, we are based on the material price at the time of signing the contract.

As a representative of high-strength fasteners,torsional shear bolts play a key role in steel structure engineering with their unique broken neck groove design and precise preload control.

Heavy hex bolts are critical fasteners in a wide range of industrial, construction, and structural applications. Their robust design, combined with precise engineering specifications, ensures that machinery, steel structures, and heavy-duty frameworks remain securely fastened under extreme loads and challenging environmental conditions. Unlike standard hex bolts, heavy hex bolts feature a larger, thicker head and stronger shank, which provides enhanced torque distribution and superior load-bearing capacity. This makes them particularly suitable for projects where safety, reliability, and structural integrity are non-negotiable.

In the field of structural engineering and heavy construction, the Torsional Shear Bolt (TSB) represents one of the most advanced and efficient fastening technologies available today. Designed to deliver consistent tension and shear performance, Torsional Shear Bolts have become an essential component in high-strength connections, especially in steel frameworks, bridges, high-rise buildings, wind turbines, and heavy machinery.
