The first person to describe the spiral was the Greek scientist Archimedes (circa 287 BC - 212 BC). The Archimedes spiral is a huge spiral mounted in a wooden cylinder that lifts water from one level to another and irrigates the field. But the real inventor is not Archimedes himself. He only describes something that already exists. It may have been designed by the craftsmen of ancient Egypt to use it for irrigation on both sides of the Nile.

In the Middle Ages, carpenters used wooden nails or metal nails to connect furniture to wooden structures. In the 16th century, nailers began to produce nails with spirals that could connect things more firmly, a small step from such nails to screws.

Around 1550 AD, the first metal nuts and bolts that appeared as fasteners in Europe were hand-made on a simple wooden lathe. Hebei Shengxin Fastener Manufacturing Co., Ltd.

Screwdrivers (screws) appeared in London around 1780. Carpenters found that screwing a screw with a screwdriver can fix things better than a hammer, especially when it comes to fine-grained screws.

In 1797, Mozley invented the all-metal precision screw lathe in London. The following year, Wilkinson made a nut and bolt making machine in the United States, and the screw was quite popular as a fixed piece because a cheap production method was found at that time.

In 1936, Henry M. Philips applied for a patent for the screw of the cross recessed nail head. This design makes the screwdriver automatically centered and not easy to slip off, so it is very popular. Universal nuts and bolts connect the metal parts together, so in the 19th century, the wood used to make the machine building was replaced with metal bolts and nuts.

Engaged in fasteners for many years, do you know the origin of the screw?

In the future, the fastener industry will become more and more formal, and the threshold for entrepreneurship will be higher and higher. In the future, there will be some large-scale enterprises, the number of SMEs will be greatly reduced, and the concentration of the industry will continue to increase.
