The origin of the bolt


The first person to describe the spiral was the Greek scientist Archimedes (approximately 287 BC-212 BC). The Archimedes spiral is a huge spiral in a wooden cylinder, used to raise water from one level to another, and irrigate the field. But the real inventor was not Archimedes himself. He just described something that already existed. Maybe it was designed by skilled craftsmen in ancient Egypt for irrigation on both sides of the Nile.


In the Middle Ages, carpenters used wooden or metal nails to connect furniture and wooden structures. In the 16th century, nail workers began to produce nails with spiral threads. These nails can connect things more firmly. This is a small step from this type of nail to a screw.


Around 1550 AD, the first metal nuts and bolts that appeared as fasteners in Europe were all hand-made on simple wooden lathes.


Screwdrivers (spins) appeared in London around 1780. Carpenters have found that tightening screws with a screwdriver can fix things better than hitting with a hammer, especially when encountering fine-grained screws.


In 1797, Mozley invented an all-metal precision screw lathe in London. The following year, Wilkinson made a nut and bolt manufacturing machine in the United States. Screws were quite popular as fixing parts because at that time a cheap production method had been found.


In 1936, Henry M. Philips applied for a patent for the cross recessed nail head screw. This design makes the screwdriver center automatically and is not easy to slip off, so it is very popular. Universal nuts and bolts can connect metal parts together. Therefore, in the 19th century, the wood used to make machines to build houses could be replaced by metal bolts and nuts.
