Features

  • Both box ends incorporate a radius corner design that engages the flats of the fastener, not the corners, providing up to 15 to 20% more torque while reducing fastener rounding, enhancing the turning of worn fasteners
  • Two different size openings on opposite ends provides broader coverage than a combination wrench, less wrenches to carry
  • Box ends are offset 45 deg for clearing large obstructions, reaching recessed fasteners and knuckle clearance on flat surfaces
  • Manufactured from high alloy steel using the most up-to-date manufacturing process and heat treat for greater strength and durability
