The Central Tools 1/2" Drive Torque Wrench, No. 97353A, which offers 250 ft/lbs of torque, has been redesigned for easier use and improved durability, according to the company. The push-through head design loads in one direction whether used in a clockwise or counterclockwise direction, creating space for an asymmetric design of the clicker and ratchet mechanism. This design improves the wrench's durability and the improved lock collar design is easier to grip and improves impact resistance, according to the company. Scale legibility is improved by shading the background to improve contrast. This torque wrench is made in the U.S.A.
