Why is it best to use the right size of Phillips type screw driver?

Using the right size Phillips screwdriver is crucial to ensure a proper fit in the screw head, which helps prevent stripping or damaging the screw. An appropriately sized screwdriver allows for better torque application, making it easier to drive the screw in or remove it without slipping. Additionally, using the correct size minimizes wear on both the screwdriver and the screw, leading to more effective and efficient work.
