Which tool is used to drive hexagonal screws?

Explanation:
Hexagonal screws require a tool that fits the six-sided recess inside the screw head. An Allen wrench, also called a hex key, is specifically shaped to engage that hex socket, providing a snug fit and good leverage to turn the screw without slipping or stripping the head. The other tools aren’t suited for this task: needle-nose pliers aren’t designed to engage the internal recess, an open-end wrench works on external bolt heads rather than internal sockets, and a measuring tape has no function in driving fasteners.
