Historic
The screws were invented about 2,400 years ago by Archytas
of Tarentum (428 BC - 350 BC), who was a contemporary of
Plato, sometimes called the founder of mechanics. The
English, through Jesse Ramsden, set up the first industrial
production line for these products in 1770. From a primitive
form, given the fact that the first material used for their
production was wood, screws have come a long way,
becoming indispensable for almost any industry, currently
having an extremely broad range of uses, including
orthopedic surgery.
