How heavy is the world's largest nut and what size is the smallest?

Kulibins Greetings, today I will tell you all that I learned about normal nut. Agree genius came up with this shtukovinku, which holds the entire global industry today.

Let me remind you that because of the usual nuts shuttle Challenger exploded.

Probably should not write that nuts first appeared on the armor of knights and connected parts together. About the fact that the nuts began to mass-produce shortly before the First World War, when it became necessary to massively sheathing wooden hulls steel bronelistami. This is the greasy facts.

But the most interesting. Considered the greatest nut nuts "Pilgrim" until recently, their so-called in honor of the plant where they were produced. These nuts weigh 4 tons and 700 kilograms. Apply them in the steel industry in special hydraulic presses.

However, this is not the biggest nut.

In the photo the world's largest mine excavator Bagger, Which weighs 14,000 tons and was assembled in Germany. Spare parts for it are manufactured in 26 countries around the world, and then transported to Germany for assembly.

Pay attention to the rotor, its diameter 21 m, and it is attached to the screw three nuts which unfortunately does not immediately seen, but I pointed out their location, as viewed when the documentary on Diskveri about this whopper. So this each nut weighs about 8 tons. I can hardly imagine what they were spinning there)))

By the way, for the production of nuts, they are only made of 12 pieces, we had to create a separate department and another bunch all related. Six pieces used on the machine itself and another 6 are manufactured as spare. After that, the plant was rebuilt under the manufacturing of wheels for railway cars.

The smallest nut in the world is used in watches and chronographs, based on these hours. The size of the nut was only 6 millimeters. He manufactured these watches and chronographs Kirov factory.

As I recall, these watches also called the general's and one of them was my grandfather, although he was not general))) But remember in his youth, his grandfather had sold the watch what the collector and some money to buy a camera "Zenith", which means they are not worth few.

Here such here entertaining stories about the most common nut))
