This combination wrench is made of chrome vanadium steel, with high hardness and good toughness. The surface is treated with professional pearl nickel electroplating technology, presenting a delicate matte texture, which not only enhances the beauty of the tool, but also is waterproof, rust proof, and durable.The metric wrench combines a precision-machined box end and open end. 15-degree angle open end is suitable for narrow working environments and supports multi-angle operation. 12-point box-end provides a more accurate fit than the 6-point box end, with a larger contact area with the nut, more even torque transmission, and distributes force to the rounded corners rather than the angular corners, effectively protecting the bolt corners from damage.
