Anecdote from the site: www.anekdot.ru
Hello dear friend, I am glad to welcome you to the Author's Channel "Timofey Mikhailov". It will be interesting for you here.
Today I will tell you about the mysterious nails that I found in the pallets. It was like this: I assembled the box of the house - baths, 8 by 12, from gas blocks. Pallets are left of this material.
I had a need to disassemble one. Taking a nail puller, I tried to pull out the board, but it was not there. The birch board was very firmly nailed to the wooden blocks.
With more effort, he pulled out the board, but the nails remained in the bar... I thought strangely. Here are powerful hardware used to fasten pallets.
Then he pulled out, with great effort, these carnations. I looked closely at them and was surprised. They had some kind of copper or copper-plated contacts.
Scroll through the gallery, to the right, there are more than 10 photos with comments and the nails themselves with "electrodes"
Well, I think the modernization has reached the nails. Now, so that the nail does not rust, and even more so does not lose its fastening characteristics, they use galvanic couple. This is when the second metal, in one product, during certain physical and chemical processes, serves as protection against corrosion. And these were my deepest delusions.
I decided on the Internet to find something about this by asking Yandex a question: Copper contacts on iron nails. But I did not find anything intelligible for this request.
It took quite a long time and changing the names in the search to calculate. Only the service with pictures helped. And here's what we managed to find out, these are drum nails for a nail gun, they are even presented on the Yandex market, just look at their price:
It turns out that due to this wire, they stay in the cage without scattering from each other. Working with such a gun, the productivity of workers in the manufacture of pallets is increased. Well, right, for a day that hand will fall off. Wave the hammer. And I was carried away, in my speculations, no one knows where... Moron...
