ABSTRACT:
A reversible ratchetless wrench having a base which extends from the wrench handle, through which extends an aperture in which a post is retained. The shape of the apparatus is such that the base is at least partially spaced from the post. Torque transmission cylinders are movably located between the post and the base in the aperture, and are capable of contacting both simultaneously. A reversing hub is non-elastically connected to the torque transmission cylinders and can move the cylinders to allow reversing of the wrench.
