ABSTRACT:
A bi-directional wrench (2) capable of ratchet type action is disclosed for turning a member (6) with equally spaced peripheral recesses in either direction without reversing the position of the wrench. The wrench includes one or more teeth (14) and a pair of supports (19,20) on either side of and spaced from the teeth of the wrench for engaging the member. The supports (19,20) and the tooth or teeth (14) of the wrench are configured to permit radial disengagement of the teeth (14) from the recesses of the member (6). In a preferred form, complete removal of the wrench from the member is prevented by the shape of the wrench to enable a true ratchet type action.
