How to use

Select the screwdriver with the matching HEX 0.9 profile printed on the rotating cap. Position the tip in the screw head and use the rotating cap to turn the screw smoothly for sensitive, controlled movement. Apply torque through the slim handle while maintaining a steady grip on the soft zone; use the quick-turning zone for rapid rotations when loosening or positioning screws, and the handle body for final tightening or controlled torque application.
