Double Box End: Features two different opening sizes 13/16" x 7/8" on a single tool.15-Degree Offset Angle: The wrench ends are angled at 15 degrees. This provides clearance for your knuckles and allows easy access to recessed fasteners.12-Point Design: Offers twice as many indexing positions as a 6-point opening, making it much easier to engage fasteners in tight or confined spaces. Lobular Drive Profile: The internal geometry utilizes a "lobular" design. This forces the tool to exert pressure on the flat sides of a bolt or nut rather than its corners, preventing fastener rounding and allowing you to turn slightly damaged hardware. Long Pattern Length: Measures approximately 12.5 inches in total length, providing excellent leverage for breaking loose stubborn or rusted fasteners. Premium Construction: Forged from high-alloy steel and heat-treated for optimized hardness, strength, and spring resistance. It typically features a full-polish chrome finish.
