Wiha Tools 77167 7/64″ Hex 3/8″ Drive Bit Socket

Wiha Hex bit sockets feature our standard insert bits in a square drive socket. Allowing you to use a square drive ratchet to get more torque and access areas that screwdrivers cannot. The bit sockets make it easy to replace the bit with a hex set screw that holds the insert bit securely, in the event the bit needs to be replaced.
