BSP Fittings supplier shares with you: the earliest application of threading technology predates the bronze age (before 2500 BC), when threads were used for equipment and weapons, as well as jewelry decoration. Threads were favored for columnar structures in ancient buildings, and threaded connections first appeared in the 3rd to mid 7th centuries.
The earliest humans used threads to apply pressure to threads, and it was invented by Greek mathematician Aquitas, the founder of mathematical mechanics, before 428-350 BC. The thread principle used in this period is made of wood material which is usually used for olive oil and grape juice extraction.
Later, more than 300 BC, the Greek mathematician Archimedes promoted the use of threaded structures to take water, and transported the water from the low to the high places through threaded equipment. But it is also said that prior to Archimedes, the Egyptians have started to use this water extraction technology to irrigate and remove bilge water.
How was the first threaded part made in the world? We may get inaccurate and accurate answers. Who made the first threaded part was a screw or a bolt, or a screwed fitting, and it is unclear. But we can imagine it, just like the ape evolved into a sapiens.
Over the course of thousands of years of evolution, humans slowly, from the use of stone tools, to the use of bronzes, to iron, summed up experience little by little in labor and accumulated wisdom. How to connect firmly, vine made of trees? A rope made from hay? Use animal leather? Slowly, through various observations and experiments, threaded parts appeared. It is difficult for us to go back to ancient times. It is that corner of the world who made the first threaded part. The earliest threaded parts were made of wood, used to make wine juices, pressed with olive oil, and also used to press cloth. The use of metal bolts and nuts as fasteners has been a thing of the 15th century.
Metal threads and nuts were used to fix objects until they appeared in Europe in the middle of the 15th century. In the 16th century, threaded joints were widely used in firearms. The screw groove structure allows the parts to fit tightly to avoid vibrations during gun shooting. At the same time, threaded connections are also widely used to connect armor.

The factory's quantitative production of threads only began in the mid-18th century. The grinding of the spiral groove depends on the eyesight and manual skills of the craftsman. New developments were made in the 18th century on thread grinding. Antoine Thiout invented the lathe auxiliary equipment-screw drive at about 1750, so that the carriage can move in semi-automatic linear motion. Jesse Ramsden manufactured the first thread-cutting lathe in 1770 to produce precision grooved threads. The fine threads allow the same fine tools to be manufactured, such as steam engines, machine tools and measuring equipment. After the production of a series of auxiliary equipment, the construction of tunnels, roads and bridges has been further developed.
