Screws

Archimedes is credited with inventing the screw in the 3rd century BC, however his screw was not a fastener but two contraptions incorporating screw-type devices. One device was a water pump; still used for industrial applications, now known as the inclined screw conveyor. The second was the endless screw, which is the threaded worm of a worm and gear set.
