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.
