3Pcs Combination Wrench 24Mm Metric 12-Point Box & Open End CR-V Steel

This open/box end wrench, made of chromium vanadium (CR-V) steel, combines high strength, high hardness, corrosion resistance, good toughness, wear resistance, and durability. The surface is treated with a black electrophoretic coating, which is wear-resistant, scratch-resistant, and has excellent rust-proof properties, effectively preventing oxidation and corrosion and ensuring long-term durability. This spanner tool combines an open-end and a 12-point box end. Open end is suitable for narrow working environments, and the 15° opening angle design provides greater rotation space, supporting 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 bolt, more even torque transmission, less slippage, and distributes force to the rounded corners rather than the angular corners, effectively protecting the bolt corners from damage. These versatile wrenches are widely used in DIY projects, car repair, appliance repair, plumbing repair, and machinery repair. This versatile and reliable tool is suitable for various manual repair and assembly scenarios, making it an essential tool for both 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 at work and even damage the tool and bolt.
