Do you know the Origin of Screws?

As a Spiral Screw Manufacturer, share with you. The first person to describe the spiral was the Greek scientist Archimedes. The Archimedes spiral is a huge spiral in a wooden cylinder that is used to lift 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, and maybe it was designed by artisans in ancient Egypt for irrigation on both sides of the Nile.

Spiral Screw

In the Middle Ages, carpenters used wooden or metal nails to connect furniture with wooden structures. In the 16th century, nail makers began producing nails with spirals. These nails were able to connect things more firmly. This was a small step from this type of nails to screws.

Around 1550, the earliest metal nuts and bolts used as fasteners in Europe were made by hand on a simple wooden lathe.

Screwdrivers appeared in London around 1780. Carpenters have found that tightening screws with a screwdriver can hold things better than hitting them with a hammer, especially when you encounter fine-grained screws.

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

In 1936, Henry M. Philips applied for a patent for a screw with a cross recessed nail head. This design is popular because it automatically centers on the screwdriver and does not slip easily. Universal nuts and bolts can be used to connect metal parts together. Therefore, by the 19th century, wood used for manufacturing machines to build houses could be replaced by metal bolts and nuts. Spiral Screw is a tool that utilizes the physics and mathematical principles of the beveled circular rotation and friction of an object to gradually tighten utensils and parts. Screws are a generic term for fasteners, spoken daily. Screws are an indispensable industrial necessity in daily life: extremely small screws used in cameras, glasses, clocks, electronics, etc .; as for engineering, architecture, bridges, large screws and nuts are used; transportation equipment, aircraft, trams, automobiles Use the same size screws. Screws have important tasks in industry. As long as there is industry on the earth, the function of screws is always important.

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