12MM key

The common screw key is an essential tool in maintenance and repair work, characterized by a design that combines an open end and a toothed closed end, providing flexibility in use. Made of high-quality chromium vanadium coated steel, making it resistant to corrosion and rust and ensuring durability with repeated use. Suitable for a wide range of tasks, whether in mechanical workshops or household uses. How to use: Choose the appropriate size for the screw or nut to be tightened or loosened. Use the open end to reach tight spaces and protruding nuts. Use the toothed closed end to provide a firm grip and higher torque. After finishing, make sure to clean it and store it in a dry place to preserve it. Storage tips: Keep in a dry place away from moisture to avoid rust. It is recommended to clean it after each use to maintain its quality. Preferably place it in the toolbox for easy access. Avoid exposing it to strong shocks to maintain its design accuracy.
