Hello mate
Step-by-step explanation:
A screwdriver allows you to tighten a screw by turning the driver clockwise and loosen it by turning counterclockwise. It has a tough steel shaft with a bit on the end of the blade attached to a square, round or hexagonal plastic, metal or wooden handle.

A screw driver is used to tighten the screw because:-

2. It has thin end to handle the load (screw) efficiently by fitting into it.
