Abstract
A wrench has a socket defined by a plurality of flat faces and a handle. A first threading tool is provided having a shape and dimension to fit into the socket. An adapter that retains a second threading tool includes a connector having the same shape and the dimension as the first threading tool that fits into the socket. A retaining member is rotatably mounted to the body for movement between a first position and a second position for locking the adapter and the die in the socket. The retaining member has a second plurality of flat faces defining an opening where the second plurality of faces are coextensive with the faces of the socket when the retaining member is in the first position and are offset from the faces of the socket when the retaining member is in the second position.
