Chrome Vanadium Steel: Metric wrench is made of selected chrome vanadium steel with high hardness and high wear resistance, which is very suitable for twisting screws or nuts. The surface is chrome-plated to ensure its durability and corrosion resistance, extending its service life. Advantage: 45-degree offset handle can go over obstacles, helping you to use and operate easily in tight spaces. The 12-point box end design provides additional grip and control, and evenly transmits torque to the contact surface to prevent slippage. Widely Used: The compact double-end design can be widely used to tighten or loosen nuts and bolts in many narrow spaces. Suitable for DIY handicrafts, home maintenance, mechanical repairs, plumbing repairs, automotive repairs, and most general repairs. Note: Make sure to use a double-ended wrench that matches the size of the screw or nut to avoid damage or slippage; when using an offset double box end wrench, make sure the angle of the wrench is aligned with the bolt or nut for better force transfer and operation.
