An apparatus featuring a unique box wrench having a dual hinged socket is shown. A first element of the socket forms the distal end of a handle or lug. A second element engages the first element to form a socket cavity. The two elements are hinged to each other approximately halfway around the socket cavity. A pin can be inserted through a hole in the hinge teeth at both hinges in order to form the socket. Conversely, either pin can be removed from the hinge teeth to open the socket. Each hinge of the socket comprises an interlocking tooth profile in sectional view.
