ABSTRACT:
Standard ratchet wrenches are improved by including swiveling socket drive-tangs within their rotatable drive components. In wrenches using rotatable ratchet gears, the gear comprises a bore and pin that receives a slotted ball tang. The bore further may be threaded to receive a threaded locking bolt that serves to bias the ball tang into a gradual to full locking position. A press and lock button is also described. The invention is depicted in ratchet wrenches using rotatable pawls and in pneumatic drive wrenches which may use either rotatable pawls or gears. Various modifications of the wrenches' components are described and illustrated, as well.
