A screw is a fastening element.
A screw is a device used to hold an object. It has an elongated and threaded body (shank) that is inserted into the surface and a head that has slots so that a tool can be used and thus exert the corresponding force for fixation.
Typically, screws are used in conjunction with dowels . Suppose a person wants to fix a mirror on the wall. First you will make a hole with a drill and then insert the dowel. With the plug already installed, you will need to place the screw in it: for this, you will use a screwdriver that allows you to turn the screw little by little. Finally you will hang the mirror.

Depending on their purpose, screws have different characteristics. The most common screws are made of metal for their resistance. Screw heads also vary, which is why there are oval head screws , flat head screws, Phillips screws (with cross slots) and others.
Sometimes, screws are not inserted into a wall, but rather go through threads to fix different parts of the same mechanism or gear. For this it is necessary that the nuts and screws have the appropriate sizes to complement each other.
