Nut spray patent

"Japan never loosens nuts, and the open design principle cannot be copied." The magic emphasized here is the manufacturing difficulty of nuts, not the design principle. There is no doubt that the Japanese technology and superb skills in manufacturing high-precision equipment and parts are worth learning. This is also one of the reasons why Japan is strong.

However, we don't need to deify this nut too much, and we don't need to say that it exists in the sky and there is nothing underground. The Japanese government has never listed this nut as a key protection technology and an embargoed substance, which shows that this nut is not irreplaceable. Many countries in the world can do it if you really make up your mind. It's just that since I can buy it easily, I don't care. It is not a huge market and innovative high-tech technology.

The difficulty in manufacturing this nut is not the design principle, but its design principle is not complicated at all, and many people understand it. Its difficulty lies in two aspects, one is the cognition of materials, that is, the choice of materials. A good product must have good materials and a unique knowledge and understanding of materials. The other is the exquisite craftsmanship in the manufacturing process. These two points, the first is easy to solve, and the second is the problem!

So the uniqueness of this nut lies in people, in people's superb skills, in people's Excellence, and in people's pursuit of perfection. Such people are the most rare. There are not many people in this Japanese company, but everyone is an elite and has been trained for a long time. The greatest value and core of this screw lies in people, not in design, which is the magic of this nut.
