GearWrench® Metric 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. 7 Piece Metric Flexible head Drive Type: 12 Point Contains Sizes: 10 mm, 12 mm, 13 mm, 14 mm, 15 mm, 17 mm and 19 mm Finish: Mirror Polish Fully hardened All metal construction Knurled side beam for ratcheting direction indicator Flex head tilts up to 180 degrees at any interval 72 teeth ratcheting box end needs as little as 5-degrees to move fasteners versus 30-degrees for standard box end wrenches Surface Drive® on box end provides off-corner loading for better grip and reduced fastener rounding Serrated beam allows you to feel which way to pull.
