How to use

Insert the 2 mm hex end into the fastener head, applying steady pressure while turning the long arm to achieve the required torque. Use the short arm for higher torque by holding the long arm and turning the short end. Ensure the hex key is fully seated in the fastener to avoid rounding the head. After use, store in a dry place to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment when working with machinery. Avoid applying excessive force beyond the tool's rating to prevent damage to the hex key or fastener; select a larger size or a different tool if required.
