It is constructed of chrome vanadium steel, which combines the corrosion resistance of carbon alloy steel and chrome with the strength of vanadium. It has a 15° box-end offset angle and 6 points. Sold individually.

About Combination Wrenches

These two-in-one tools let you quickly switch between an open-end wrench on one end of the tool and a box wrench, spline wrench, or socket wrench on the other end, unless noted. The box, spline, or socket wrench provides better torque and less risk of slippage than the open-end wrench; the open-end wrench can approach the fastener from the top or side, which is useful in obstructed areas.

Each head fits a specific size of fastener, and both heads are usually suited for fasteners of the same size. The box, spline, or socket wrench may tilt or be set at an angle to the handle for better access to hard-to-reach fasteners. The inside edge of the box, spline, or socket wrench will have multiple points. 6-point box wrenches make contact with all sides of a hexagonal fastener, reducing the risk of stripping or rounding the fastener when turning it. 12-point box wrenches can be repositioned with a smaller movement of the handle than a 6-point wrench, which is useful when working in tight spaces.

A good choice for a range of everyday applications, these combination wrenches will get the job done.
