• 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
