ABOUT THE PRODUCT
Tension Control Bolts (TCB), manufactured under license by SATEC STEEL, are installed using a shear wrench system and provide an efficient and reliable solution for high-strength preloaded structural connections.
Their installation system ensures that the design-specified pretension is achieved according to the bolt diameter, guaranteeing proper slip-critical performance and uniform assembly control, while significantly reducing installation time as well as inspection and supervision requirements.
The break-off of the calibrated spline allows for immediate visual verification, minimizing the risk of installation errors and providing site inspectors with assurance that connections comply with structural design requirements and applicable standards.
Due to these advantages, TCB bolts replace conventional high-strength bolts and traditional fastening systems, ensuring precise control of the required pretension in accordance with structural demands.
High-strength TCB bolts have a wide range of applications, including splice plate connections, beam-to-beam connections, column splices, and beam-to-column connections. They are widely used in buildings, bridges, and industrial structures, offering high tensile strength, ductile performance, and structural reliability.
