About Origin of screw
Early screws appeared in the first century CE and were used in wine and olive presses. The Robertson screw, invented in 1908, improved over slot heads by preventing screwdriver slippage. Phillips head screws, invented in the 1930s, made assembly lines faster with their ability to.

A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the head. The most common uses of screws are to hold objects together and there are many forms for a variety of materials. Screws might be inserted into holes in assembled parts.

It is considered by some that the screw thread was invented in about 400BC by Archytas of Tarentum (428 BC - 350 BC). Archytas is sometimes called the founder of mechanics and was a contemporary of Plato. One of the first applications of the screw principle was in presses for the extraction of oils.
Let us begin with the screw, a fastener that keeps the roof over our heads and the floor under our feet. The screw thread is believed to have been invented around 400 BCE, by Archytas of Tarentum, a Greek philosopher sometimes called “the father of mechanics.” The general principle of the screw was.
The concept of a screw can be thought of as the “slope mechanics” of a helical helix wrapped around a cylindrical rod. The origin of such a concept can be traced back to the construction of the ancient Egyptian pyramids in the twenty-seventh century B.C. [1]. Although there is no precise.
