What is the primary function of a screwdriver?

To cut wood
To fasten or loosen screws
To measure distances
To route edges

The correct answer is: To fasten or loosen screws

The primary function of a screwdriver is to fasten or loosen screws. This hand tool is specifically designed to fit into the head of a screw, allowing for easy manipulation of the screw's position. By turning the screwdriver clockwise, a user can tighten the screw, while turning it counterclockwise will loosen it. This essential function makes screwdrivers a vital tool in various applications, particularly in construction, repairs, and assembly tasks. In contrast to the other options, which reference tools or tasks unrelated to the function of a screwdriver: cutting wood typically requires a saw, measuring distances involves tools like tape measures or calipers, and routing edges is a task best performed with a router. Thus, understanding the unique role of a screwdriver as a tool for fastening and loosening screws highlights its importance in both professional and DIY projects.
