A self actuating torque tool includes a shoe having at least one guide track lying in a plane, and at least one jaw. Each jaw has a follower paired with a pivot axis normal to the plane of the guide track. The follower travels along the at least one guide track between an extended position and a retracted position. There is a drive coupling through which torque is applied to the shoe. One of left torque or right torque is applied to the drive coupling causing the follower to travel along the at least one guide track moving the jaw to the extended position, and another of left torque or right torque is applied to the handle causing the follower to travel along the at least one guide track moving the jaw to the retracted position.
