KD Tools (KDT9922) FLEXHEAD GEARWRENCH
Features and Benefits: Ratcheting box end needs as little as 5 degrees to move fastener vs. 30 degrees for standard box end wrenches. Surface Drive® design nearly eliminates fastener rounding. Flex head tilts up to 180 degrees at any interval. Adjustable set screw allows you to set desired head tension. Serrated beam allows you to feel which way to pull.
