Abstract: A ratchet includes a handle and a head, the head has an open receiving surface wherein an insert is disposed therein and of a size smaller than the open receiving surface. A portion of the open receiving surface includes a bearing surface against which the insert rotates, the insert configured for engaging a conventional head of bolt or the like. A movable stop is disposed within another portion of the open receiving surface adjacent the insert and the bearing surface in a manner such that when the insert is caused to rotate in one direction relative to the bearing surface the stop is frictionally drawn into lodging engagement with the insert and bearing surface to preclude further rotation of the insert and fixably secure relative position between the insert and the bearing surface whereby the rotation of the threaded member is effected and when the insert is caused to rotate in an opposite direction, the stop is driven into a dislodged position.
