Abstract
An impact wrench is disclosed. The wrench has a handle and a housing pivotally secured to one end of the handle. A socket drive cooperates with the housing and the socket drive receives a socket for engagement with a fastener. A follower is associated with the housing and holds the socket drive in either a first or a second position allowing the wrench to rotate the fastener in either direction and the socket drive being biased to maintain the follower in one of its positions. The socket drive has first and second camming surfaces and when the housing is struck by an impact implement, the following moves relative to one of the surfaces and the socket drive is caused to rotate relative to the housing.
