ABSTRACT:
A ratchet wrench includes a handle, a housing attached to said handle, a ratchet gear mounted for rotation in said housing, the ratchet gear having an axis of rotation extending through the housing, and means connected to the ratchet gear for turning a threaded fastener. A pawl is mounted on the handle about a pivot axis that extends through the handle, the pawl pivoting among a first position in which the pawl permits unrestricted rotation of the ratchet gear, a second position in which the pawl engages the ratchet gear to prevent rotation of the ratchet gear in one direction, but allows rotation of the ratchet gear in the opposite direction, and a third position in which the pawl engages the ratchet gear to prevent rotation of the ratchet gear in the opposite direction, but allows rotation of the ratchet gear in the one direction. A method for turning a threaded fastener is also included.
