Cordless ratchets are battery-powered tools used to tighten and loosen nuts and bolts. Cordless tools don’t have cords or air supply lines that can limit access to tight or recessed spaces or cause a tripping hazard. These power ratchets have a square drive that holds interchangeable sockets that fit the drive and the fastener. They turn fasteners in small increments without having to reposition the tool, so it can work faster than nonratcheting wrenches and make 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.
