An inclined plane wrapped helically around an axis forms a SCREW. The 'pointy' ends of the inclined plane become imaginary. The remaining edge of the inclined plane becomes the threads of the screw.

A screw is a fastener that is similar to a nail, but it has threads.
The hole that you put a screw into is referred to as a "tapped hole". The rib-like things in the hole are called "threads" or, more specifically, "internal threads" as opposed to the external threads on a screw.
The threads of the screw as the threads are turned by the screwdriver .
The threads are what make it work. As you will know if you have tried to use a screw with stripped threads, it is useless. That is because a screw is a simple machine built from an even simpler machine: the inclined plane. The threads are an inclined plane wound around the outside of the screw, and are what change the twisting motion into a lifting motion.
§ Screw threads have better compression strength than other threads. § Due to low thread angle there is no radial pressure on nut. § Due to smaller angle, the lead of screw is less.
