At each dacha, the owner has his own workshop, where tools are stored. Naturally, a large number of small, but very necessary details accumulate in it. These are bolts, nuts, washers, gaskets and many other little things. Usually they pour all this into some kind of box or try to sort it out into containers. Naturally, finding the right bolt at the right time is very difficult, and there is always not enough room on the table.
But here is an interesting solution. Now bolts and nuts can be stored in glass jars, with lids for thread. Fasten them to the upper crossbar, and then wind the jar onto the lid. The method is not very reliable, but very practical.
