Square Drive Adapters for Power Tools


Attach your square-drive sockets to drills, powered screwdrivers, and other tools that accept a hex shank. Not for use with impact tools.
Adapters with ball detent, the standard retainer style, have a spring-loaded ball that holds the socket in place, allowing you to slide it on and off quickly. Adapters with a pin style retainer provide a more secure hold than ball detent style because you have to depress the pin to attach or remove the socket. Also called positive locking.

Impact Square Drive Adapters for Power Tools


Attach your impact square-drive sockets to power drills, impact drivers, and other tools that accept a hex shank. These adapters are made to withstand the high torque and force of impact tools.
Adapters with ball detent have the standard retainer style. A spring-loaded ball holds the socket in place, allowing you to slide it on and off quickly. Adapters with a pin style retainer provide a more secure hold than ball detent style because you have to depress the pin to attach or remove the socket. Also called positive locking.
