Beta 910 Series 3/8" Square Drive Sockets and Socket Drivers
The Beta Tools 910 Series covers standard 3/8" square drive sockets and hand socket drivers. They are fully compatible with any other brand using a standard 3/8" square drive.
The 3/8" drive size is a good all-purpose size. It is large enough to break loose or tighten most automotive fasteners (except lug nuts and other very large fasteners), but compact enough for most jobs.
