It is quite possible that even if the Ferrari mechanics had checked the left rear hub the damage might have been apparent. The parts may have needed to be under load to see/feel the failure. I agree that it is quite possible the damage would have been apparent if they had looked at the part.

They would have had to disassemble the left drive axle I think. That is usually only done between races as maintenance. |

^^ This, quoted below, is from the article. I have no ides if the "domed center part with the ears is the nut. or not. but by looking at the pic it appears to me the the two ears are bigger than the center hole of the assembly. The wheel nut design on the Mercedes (pictured above) is not like those fitted on road cars. Instead, it is custom built and is dome shaped. It features two vertical extensions that are captured by the wheel gun to rotate the nut on and off. It was these extensions that were machined off during the Bottas stop and meant the gun had nothing to grab on to.  |

The two 'vertical extensions' are the fail safe wheel/nut retainer. And yes, the two ears are bigger than the center hole of the assembly because they are designed to keep the wheel from coming completely off the hub and only allow it when the socket is applied pushing them back in to the hub. Typical current F1 wheel nuts and socket:
One color is LH thread, the other RH thread. You'll notice that the small center diameter is to just fit over the 'dome' on the hub to depress the locks (wings).

I know. That's why I added the disassembly aspect. |

It was these extensions that were machined off during the Bottas stop and meant the gun had nothing to grab on to. The article's author sounds like a fan boy that got a job writing about fast cars, the inside of the gun doesn't grab those "ears" it's inside is shaped to push them in. As the gun turns the wheel nut it backs off the stud hub enough to hold the safety retaining "ears" in itself allowing the wheel to be removed. The back of the nut is shaped to push the ears in when the new wheel in put on. I find it hard to believe the nut was cross threaded as they were taking it OFF, more that likely something happened as it was being installed that wasn't caught by the team. They should also check the wheel that was on the car before the race tire was fitted to see if it's threads were damaged, maybe metal from that wheel nut contaminated the threads of the hub. |

The F1 IG has a slow motion video of that specific gun/wheel in action at the pit stop. When the gun gets started you can see all the debris flying off. When it is removed from the nut you see that those 16 or so ears around the perimeter are machined off. Oops. I can't link here as I don't have IG on my desktop

^Uh hu, yet the other three guys had NO problems adjusting to the situation. The demasculinization of Bottas continues in earnest.  |

I will have to see a picture of the actual damaged part before I can understand how this system actually works. The center part with the "ears" seems to be (part of) the axle assembly and the ring with the 13 (yes thirteen) splines is the nut. Am I wrong?  |

Apparently the Nut Gun used by MB acted like a portable lathe and machined the 13 splines to nothing so that the nut would not come off. |

So, the Nut-Gun must have been improperly/incompletely mated to the nut for that to happen. From wear?
