Abstract
A reversible ratchet device is provided as a low-torque application wrench in the form of an elongated body carrying a ratchet mechanism thereon, the ratchet mechanism being operable under low-torque conditions such as are present with initial driving or final loosening of a workpiece. The device includes the ratchet mechanism carried directly on the body, both being co-axially rotatable with each other and with the workpiece.
