Note: It is written in the books that you should use the M7 thread by enlarging the M6 thread. Only that this is an unusual thread and hardly anyone has such a tap at home, not to mention the M7 screw. That's why I chose the M8 thread instead of the M7.
Before increasing the size of the thread, e.g. from M6 to M8, check whether in the element fastened with this screw you can make a hole with a larger diameter, e.g. for an M8 bolt, the hole must be fi9 [mm] for the screw to pass through it. If this is not possible you have to use the next two methods where the bolt stays the same size.
Repair kit: SATRA S-X38B
I do not recommend reaming on the M8 because it looks bad, and the self-tapping insert is too large so you can damage the entire socket.
If I can do something better, write in the comment, I will know for the future.
