Abstract: An adjustable socket wrench in which the ratchet head is orthogonally pivotable with respect to the wrench handle. A ratchet housing is integral with one end of the handle and has a substantially circular hole therein. The hole has a partially spherical interior surface with first and second flat portions on opposite sides of the hole so that the flat portions are substantially parallel to the longitudinal axis of the handle. A ratchet head is mounted within the hole and has a partially spherical exterior surface which movably fits within the ratchet housing interior surface. The exterior surface has third and fourth flat portions which slidably abut the first and second flat portions. The ratchet head is pivotable within the ratchet housing about an axis orthogonal to the flat portions and perpendicular to the longitudinal axis of the handle. A conventional ratchet device is mounted within the ratchet head and has a drive member which is movable, with a ratchet action, with respect to the ratchet head.
