A socket wrench incorporating both English (inch) and Metric sizes. Two conventional single-size sockets are replaced by a dual-size hex pattern socket, reducing the number of sockets likely to be needed to do a job. One hex pattern is sized to match preferably a Metric component and the other hex pattern is sized to match preferably an English component. The two different sized hex patterns are preferably offset by 30 degrees.
