History of Screws
Ancient Beginnings
First Appearance: Screws date back to around 400 BCE. The earliest known screw-like tools were used by the Greeks and Romans. They were used primarily in presses for wine and olive oil extraction.
Wooden Screws: Early screws were made of wood and used in devices like presses and simple machinery.
Medieval Period
Metal Screws: By the medieval period, screws began to be made from metal, primarily by blacksmiths.
Increased Use: Metal screws were used in a variety of applications, including armor and early machinery.
16th to 18th Century
Threading Innovations: In the 16th century, the first metal screws with threading were documented. Innovations in threading technology improved the effectiveness and utility of screws.
Lathe Invention: The invention of the screw-cutting lathe in the 18th century allowed for more precise and consistent production of screws.
Industrial Revolution
Mass Production: The Industrial Revolution in the 19th century brought about significant advancements in the mass production of screws. Machines could now produce screws with greater consistency and precision.
Standardization: The development of standardized screw threads, such as the Whitworth thread in the UK and the Unified Thread Standard in the US, facilitated interchangeability and increased the use of screws in industrial applications.
Important Applications in Current Industry
