How do you describe a screw?
A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force . It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside.
What is the advantage of a screw?
The mechanical advantage of using a screw involves the spreading of the effort over a longer distance thereby allowing heavy loads to be overcome with a smaller amount of effort . This means if you can twist your screwdriver with a force of IN you can generate a force of 4N.

Does a screw push or pull?
When you twist a screw into a piece of wood, you exert an input force on the screw. The threads of a screw act like an inclined plane to increase the distance over which you exert the input force. As the threads of the screw turn, they exert an output force on the wood, pulling the screw into the wood.
