When vertical space is tight or you need an extra twist on your socket, use these dual-drive hex bit sockets. They work with a standard square-drive tool and a box or open-end wrench. Tighten them with your square-drive tool and give them an additional turn with the leverage from your open-end or box wrench. Or just use a box or open-end wrench when you can’t fit your square-drive tool. Pair them with hand-drive tools only.
