GearWrench SAE Flex-Head Combination Ratcheting Wrench Set combines the speed of a ratchet with the access and control of a wrench. The handy flex head tilts up to 180-degrees at any interval for excellent access to fasteners, and it has a spring washer design that provides continuous head tension. The serrated wrench beam allows you to feel which direction to pull. 72-teeth ratcheting box end needs as little as 5-degrees of movement to turn fasteners, versus 30-degrees on standard combination wrenches. The small ratcheting box end head design enables access to tight spots where a ratchet won't fit. The open end allows ratcheting of nuts and bolts without removing the wrench from the fastener, making jobs go faster and easier.
