This 12-point box and open end wrench is made from CR-V (chromium-vanadium) steel and is fully heat treated to provide exceptional hardness, strength, toughness and durability, making it highly resistant to wear and deformation in a wide range of applications. Wrench surface is chrome-plated to prevent rust and corrosion, ensuring a long service life. The surface is smooth and feels comfortable.Multi-purpose wrench combines the functions of a 12-point box end wrench and an open-end wrench. The open end provides easier access in tight spaces, while the box end allows for higher torque application. 12-point design grips the fastener from all sides, providing more points of contact and reduced risk of slippage, as well as allowing for easier engagement of fasteners in tight spaces and more angles for applying torque.
