A wrench ratchet mechanism has a driven member, a housing having a chamber in which said driven member is at least partially received and a torque transmitter disposed between the housing and the driven member to transmit an applied torque from the housing to the driven member. The torque transmitter is deformable from a non-torque transmitting condition to a torque transmitting condition in response to rotation of the housing in a first direction and returnable to the non-torque transmitting condition in response to rotation of the housing in a second direction that is opposite the first direction. |
