Prior to discussing the screwdriver, let's talk about the screw itself. We can learn more about screws from Comrade lei Feng's diary entry, "A glimpse of two."

Lei Feng recorded the following in his diary on January 12, 1960: "Even though it is a tiny screw, is a tiny little gear, but if it is missing, that the whole machine cannot run, slow to say that the lack of it, even if it is a small screw is not tightened, a small gear slightly broken, but also to make the operation of the machine malfunction, in spite of this, but then good screws, and then precision gears, if it leaves the machine as a whole, but also inevitably to be treated as scrap, thrown away as waste. But even with the best screws and most advanced gears, it's not a given that the machine will be treated as garbage and dumped in the scrap metal material storehouse if it breaks down as a whole."

Lei Feng wrote once more on April 7, 1962: "A person's role for the revolutionary cause, like a machine on a screw. The machine's enormous working capacity is made possible by the numerous screws that hold it together and make it a solid whole. Despite its small size, screws play an incalculable role in this process, so I would like to constantly use them. To prevent rust, screws need to be cleaned and maintained on a regular basis. The human mind is the same; it needs to be checked often to ensure that nothing goes wrong."

We do not discuss the spiritual elements of things, but the importance of screws in the industry is obvious. The "New York Times" in the United States released a selection of the "best tools" for the "human epoch since the second millennium" in 2000, and a little screw was the top choice.

Screws are utilized extensively in many different industrial domains; big ships, airplanes, tiny glasses, and cell phones are all inextricably linked to screws; these goods are referred to as "industrial rice" and are fastened with a screwdriver.

Even though the Job and William Wyatt brothers' business failed commercially, they made a significant contribution to the low-cost manufacturing of screws, which ultimately led to a large increase in the number of screws and the popularity of screwdrivers. Prior to the first industrial revolution, screws were difficult to produce.

Screw production thrived due to constant efficiency and dimension standardization, and the boom was largely attributed to the improved precision of screws. Screwdriver technology improved and expanded together with the steady rise in use of screws for industrial use.

Nowadays, every household is inseparable from the use of screwdrivers to DIY!
