Finger trick: how car service technicians select the right hexagon by eye

For fastening various types of elements, many modern car manufacturers use not the traditional “cross” and certainly not the keyway version, but Torrex – a polyhedron that allows you to tighten the fastener without the risk of “licking” the bolt head. In auto repair shops, technicians determine the size of the bit the first time, but how do they do it? Just experience it? But no!

From childhood we have learned: the work of the master is feared. Don’t worry, if you are not a specialist, turn to a professional. They simply forgot to add that in our time you can only trust yourself, and you can become a good master on your own if you set such a goal for yourself. The best way to learn is to see a professional at work with your own eyes, and don’t forget to ask questions. Fortunately, they seem to have moved away from the stupidity of banning customers from visiting the repair zone.

It is always pleasant to watch the work of an experienced mechanic: firstly, the school literature book teaches us that work is for good. Even the writer Gorky, who loved to work very much, went to the port every Saturday and watched the work of the loaders. Second, everything works for a professional; the tool (whether it is a wrench or a hexagon) is selected the first time. With the eye, the problem is literally identified and solved just as cleverly. Experience is invaluable, but many operations that at first glance seem like pure magic have a fairly simple explanation. And the trick with selecting an “asterisk” or a hexagon is one of them.

The customer, idly wandering around the workshop, will not notice that before going to the workbench with tools, the master puts his fingertip on the head of the bolt and presses hard, obtaining an exact impression of the desired head. Selecting an instrument with such a “cast” is a matter of minutes. And it will save a lot of time, especially in the context of a 12 hour shift, and from the outside it will look like a cool professional.

An experienced mechanic does not and cannot know the peculiarities of all the cars in the world, but he knows the working methodology, understands what, where and why, where to start and how to end. Over the years, this skill has been honed into aerobatics and is called that same experience that cannot be purchased or passed on through inheritance. But like we said, you can spy…
