    Nuts and bolts of mechanics from the fourth century B.C.
    It is considered by some that the screw thread was invented
    around 400 BC by Archytas of Tarentum (428 BC - 350 BC).
    Archimedes, however, developed the screw principle and used
    it to construct devices to raise water. The Romans already
    applied the Archimedean screw for mine drainage. Archimedes’
    understanding of mechanical devices such as the lever, pulley
    and screw, laid the foundation for the science of mechanics.
