What size screwdriver should be chosen for a particular screw?

Choosing the appropriate size screwdriver for a screw is essential for both efficiency and the prevention of damaging the screw or the material it is driven into. A large screwdriver is suitable when dealing with screws that have a wide head or are particularly deep, as it allows for proper grip and torque when turning the screw. Using a larger screwdriver ensures that it fits snugly into the recess of the screw head, providing sufficient leverage to drive the screw in without slipping.

On the contrary, a small or narrow screwdriver might not have the necessary grip and could lead to stripping the screw, while a long screwdriver, although useful for reaching deeper screws, does not necessarily indicate the correct size for the screw head itself. Thus, selecting the large size aligns best with the requirement for a secure and effective application.
