The combination wrench is made of 45# steel, with high hardness, wear resistance, toughness, high torque, and strong impact resistance. The surface has a black electrophoretic coating, which is wear-resistant and scratch resistant, with excellent oil and rust resistance, effectively preventing oxidation and corrosion, ensuring durability.Multi-purpose wrench combines an open end and a 12-point box end. The open end is suitable for narrow working environments and supports multi-angle operation. The chamfered design of the jaws makes it compatible with corroded and worn bolts. The 12-point box end offers larger contact area with nuts for more uniform torque transmission, effectively protecting bolt corners from damage.
