Power ratchets turn fasteners in small increments without having to reposition the tool between turns to drive and remove nuts and bolts. This allows the tool to work faster than nonratcheting wrenches and makes it easier to turn fasteners in tight spaces and where high torque is not required. Power ratchets speed tasks and reduce worker fatigue as compared to hand ratchets. Their square drive accepts standard sockets that have the same attachment size as the drive. These tools provide constant torque and are suitable for light- to medium-duty fastening applications found in automotive, construction, and manufacturing applications.
