Twist-Off Tension Control Bolt Method: Tools & Procedure

Installing tension control (TC) bolts? There's a method for that. The Twist-Off Tension Control Bolt method is one of the installation methods outlined by the RCSC. Performing a pre-installation verification (PIV) ensures each bolt reaches the minimum required pretension prior to working on the structure. In this video, we demonstrate this method using a 3/4" TC bolt, a shear wrench and a bolt tension measure device to verify installation meets specifications. • RCSC specifications → https://www.gwyinc.com/resources/rcsc-specifications/.
