【Long】Hex Key Wrench Set 9-Piece Set, Total Length 20cm, Professional Specification, Ball Point This is a set of 9 hex key wrenches, **"extra-long type"**, perfect for DIY and serious maintenance. The extra-long specification has a maximum length of approximately 20cm. 【Advantages of Being Long】 Easy to turn with less force: The length utilizes the "lever principle," allowing you to easily loosen tightly fastened bolts with less effort.

Less fatigue: The size allows you to grip the entire palm, reducing hand pain during long hours of work. Product Features Ball point design: The tip is ball-shaped, allowing insertion at an angle (up to 25 degrees). This significantly improves work efficiency in tight spaces.
