The Ascot Supply 2-pc 600 ft-lb Flex Hinge Style Torque Wrench, No. 168-60012, is designed for easy storage and portability. It reduces the possibility of over-torquing thanks to its large break angle, and the wrench flexes at its hinge when it reaches proper torque. Cam control of the mechanism gives a controlled break. It offers +/- 4 percent accuracy and comes with a calibration certificate. It comes in a durable storage case and includes two adapters, 3/4" to 1" and 3/4" to 3/4".
