They are ideal for applications where a consistent force is required or where over-tightening can damage or distort a workpiece. The handle clicks when the specified torque is reached. The locking mechanism has 12 teeth. The amount of torque is set by adjusting the screw in the handle. The handle is made from 4140 quenched and tempered steel with a black or orange finish. The ratchet is made from 4115 carburized steel with a black oxide finish.
