ABSTRACT:
A torque wrench having an elongated hinge terminating in a ratchet ring with interiorally directed teeth has a work head for turning a workpiece and a pawl for selectively rotating the workpiece with rotational movement of the hinge. The pawl is provided with a lip directed radially outward from the axis of rotation of the work head. A corresponding annular groove is defined in the interior wall of the ratchet ring to receive the lip. Tilting or misalignment of the pawl within the cavity defined within the ratchet ring is thereby prevented. In its preferred embodiment, the pawl is equipped with a plurality of ratchet teeth with the lip extending outwardly from the generally convex surface into which the teeth are formed midway between the longitudinal extremities of the pawl perpendicular to the plane of the ratchet ring. The corresponding annular groove in the ratchet ring likewise divides the ratchet teeth into separate portions on either side of the pawl lip.
