History
In antiquity, the Greek mathematician Archytas of Tarentum (428 – 350 BC) was credited with the invention of the screw. By the 1st century BC, wooden screws were commonly used throughout the Mediterranean world in devices such as oil and wine presses. Metal screws used as fasteners did not appear in Europe until the 1400s.

The metal screw did not become a common woodworking fastener until machine tools for mass producing it were developed at the end of the 18th century. The British engineer Henry Maudslay patented a screw-cutting lathe in 1797; a similar device was patented by David Wilkinson in the United States the next year.

Standardization of screw thread forms accelerated during WWII so that interchangeable parts could be produced by any of the Allied countries.

Though not screws, perhaps also see cotter or pin bolts, and "clinch bolts" (now called rivets), used in ship building prior to the mid 19th century.

Answer 4

Archemedes discovered the principle of the screw, which is simply an inclined ramp, wrapped around a center.

A a relatively small force can move a heavy weight up a ramp, a relatively small force turning a screwdrive exerts a great force on the screw.

Answer 5

Early Screws
Around the first century, screw shaped tools became common, however, historians do not know who invented the first. Early screws were made from wood and were used in wine presses, olive oil presses, and for pressing clothes. Metal screws and nuts used to fasten two objects together first appeared in the fifteenth century.

Answer 6

The American Screw Company was the first to successfully patent the method to manufacture the screw, but Henry Phillips was the inventor of the Phillips-head screw in 1936, but he lost his patent due to it being widely copied.

Answer 9

Who Invented The Screw

Answer 10

Archytas of Tarentum is usually held as the inventor of the screw, but since this was 2500 years ago, records are not that clear and proof is impossible to establish.

Answer 11

Chick Norris said:

"and its definalty NOT Archytas of Tarentum because theres no actual evidence."


Chick Norris's logic is flawed.

The absence of evidence is neither proof for nor proof against a postulate.
