Unmatched Access and Speed with Flexible Precision

Navigate the tightest engine bays and obstructed machinery with the GearWrench 9901D 12-Piece Metric Flex Head Ratcheting Combination Wrench Set. These wrenches are engineered to solve the most frustrating access problems mechanics face. The flexible box end tilts up to 180 degrees, allowing you to reach around blind corners and odd angles where standard flat wrenches simply cannot fit. Once engaged, the 72-tooth ratcheting mechanism requires only a minimal **5-degree swing arc** to turn fasteners, giving you the ability to work in spaces where a standard 30-degree turn is impossible.

Built for professional longevity, each wrench is forged from premium alloy steel and finished with a bright, full-polish chrome that resists corrosion and wipes clean in seconds. The 12-point box end features GearWrench's signature Off-Corner Loading design, which drives the flats of the fastener rather than the corners. This provides a stronger grip, reduces the risk of rounding off bolt heads, and delivers high torque output. Organized in a durable plastic rack, this comprehensive metric set ensures you have the right size at your fingertips for any automotive or industrial application.

Key Features

  • Flexible Reach: Flex head tilts 180 degrees to access hard-to-reach fasteners at any angle.
  • High-Speed Ratcheting: 72-tooth gear needs only a 5° swing arc to move fasteners in tight spots.
  • Fastener Protection: Off-corner loading design grips the flats to reduce rounding and increase torque.
  • Superior Clearance: Thin head and beam profile fits into confined areas where ratchets won't go.
  • Professional Durability: Manufactured from alloy steel for exceptional strength and long tool life.
  • Quick Identification: Large size markings stamped on both ends of the beam for fast visibility.
  • Corrosion Resistant: Bright, full-polish chrome finish resists rust and is easy to clean.
  • Organized Storage: Includes a durable wrench rack for easy transport and toolbox organization.

Pro-Tip: While flex head wrenches are lifesavers for access, avoid using the flexible joint to "break loose" extremely rusted or over-torqued bolts. Use the solid open end of the wrench or a breaker bar to start the fastener, then switch to the flex ratcheting end to quickly spin it off. This protects the pivot pin and ensures your tool lasts a lifetime.
