20Mm Metric Combination Wrench 12-Point Box & Open End CR-V Steel Spanner

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. The box end features a 15 degree offset design, providing a larger working range in confined spaces. Wrench handle features a unique concave rib structure that effectively prevents slippage when applying force, thus improving operational safety. Versatile wrenches are widely used in DIY projects, car repairs, home appliance repairs, pipeline repairs, mechanical repairs, etc. This tool has diverse functions, is reliable, and suitable for various manual repair and assembly scenarios. It is a must-have for beginners and professionals. Choose the appropriate wrench according to the size of the bolts you need to tighten or loosen. Sizes that are too large or too small will cause inconvenience in work and even damage the tool and bolt.
