GEARWRENCH 20-Piece Metric Specialty Ratcheting Crowfoot and Double Box-End Wrench Set

The GEARWRENCH 20-Piece Metric Ratcheting Wrench Set provides advanced access geometry and high-speed fastener turning across hard-to-reach crowfoot and double box-end configurations. Engineered with a 72-tooth ratcheting box end requiring only a 5-degree swing arc, this professional specialty kit allows automotive mechanics and industrial equipment technicians to navigate around deep engine blocks, hydraulic lines, and cramped chassis components. Forged from high-grade alloy steel with a full polish chrome finish and flush-mounted reversing levers, each tool actively prevents fastener rounding while housing securely inside a chemical-resistant EVA foam storage tray designed for modular tool chest drawers.

Best Used For:

  • Hydraulic Line & Fitting Servicing: Utilizing metric crowfoot wrenches on 3/8-inch drive ratchets to torque fluid lines and brake fittings where standard sockets and box wrenches cannot fit.
  • Restricted Engine Bay & Manifold Fastening: Navigating around exhaust manifolds, turbocharger studs, and accessory brackets using double box-end ratcheting wrenches.
  • Modular Tool Chest Drawer Organization: Dropping the pre-cut chemical-resistant EVA foam storage tray directly into rolling tool cabinets for instant visual inventory control.

Key Performance & Safety Features

  • 72-Tooth Ratcheting Box End: Requires only a 5-degree arc swing to rotate fasteners, enabling continuous turning in extremely restricted spatial clearances.
  • Flush-Mounted Reversing Levers: Low-profile directional levers allow quick, seamless forward and reverse switching without removing the wrench from the fastener.
  • Specialized Crowfoot & Box Profiles: Engineered specifically to reach around obstructions, brake lines, and steering components that block straight-line access.
  • Full Polish Chrome Alloy Steel: Premium forged alloy steel construction resists rust, wipes clean of grease, and withstands extreme torsional stress in harsh shops.
  • Modular EVA Foam Storage Tray: Custom high-visibility laser-cut foam tray fits standard tool chest drawers for pristine shop organization and missing tool detection.
  • Full Lifetime Warranty: Backed by GEARWRENCH commercial hand tool warranty coverage for professional reliability.
