This combination wrench is made of carbon steel, with high toughness, high torque, and strong impact resistance. The surface is treated with professional chrome plating technology to form a smooth and bright silver protective layer. It not only enhance the beauty of the tool, but also 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.
