What is the history of the hand tap?

The hand tap, a tool used for cutting internal threads, traces its origins back to ancient times, with early versions found in ancient Egypt and Greece. The modern hand tap design began to take shape in the 19th century, driven by the Industrial Revolution, which necessitated more precise and efficient manufacturing methods. Innovations in Metallurgy and tool production led to the creation of standardized tap sizes and shapes, making them widely accessible for various applications. Today, hand taps remain essential in machining and DIY projects for creating threaded holes in metal, wood, and plastics.
