About 20 years ago, an engineer spoke of an unusual nut used in huge looms to quickly change spools of thread. I remember that the hole in the thread was additionally drilled, with a certain angle, relative to the main thread.
Thus, the threads were partially preserved. The worker put the nut on the threaded rod, holding it at an angle. Then he turned the nut along the axis of the thread and twisted it. This design made it possible to quickly fix thousands of spools of thread in a working day.
Sometimes, remembering this story, I tried to find a photo of such a nut, but I had no luck with the search. Does anyone have one in their collection or photograph or know exactly how it was taken.
