If you are going to unscrew the wheel bolt, but it does not lend itself in any way - do not overdo it. Perhaps you should take a closer look at it. Often it is not possible to unscrew the bolt from the wheel of the car due to the fact that all the faces on its head are simply “lapped”. In this case, the "treatment" is only radical - to drill!
How to drill a bolt
Most often, automobile wheel bolts have a small recess inside the head, so it will not be difficult to find a center. However, before drilling, you must first measure the distance from the cone of the bolt to the edge of the cap. To do this, you can remove the bolt from the same or another wheel and measure the depth using a caliper.
If, for example, the distance from the edge of the cone to the edge of the cap of the bolt is 20-22 mm, then it is precisely at such a depth that a hole must be drilled. The drill must be selected with a diameter so that it freely enters the recess on the head of the bolt (usually 10 mm).
After that, you need to drill the hole obtained with a drill of a larger diameter (that is, if you took a drill of 10 mm, then the second time you need to drill with a drill of 12 mm). Then, taking a thin drill 6-8 mm, it is necessary to delve into the "body" of the bolt by about 5 mm.
At the last stage, you need to break off the head of the bolt using a hammer and chisel. Since after drilling with a 12 mm drill the wall became thin, then, as a rule, a few strokes are enough for the hat to fly off. Then it remains only to hammer the torx head into the hole of the remaining hairpin and unscrew it.
This method is very simple and effective, and especially it helps out when you urgently need to go somewhere and there is no time to mess around in the garage. See how this all happens in practice.
