When Bottas pitted the wheel gun stripped the wheel nut, rounding it off, and leaving no faces for the tool to drive on. This was one of those moments where F1 TV's Pit Lane Channel came into its own. 2/8
I believe the key moment (caught on camera by @F1JMT) was only shown in detail on the PLC. You could see the swarf (metal) coming off the nut as the mechanic tried to remove it (can't really see it in these screen grabs!). Director Tom was quite excited by this. 3/8
As the nut was completely stripped there was nothing the team could do to get the wheel off and it will have to be removed in the next couple of days at the Mercedes factory. 4/8
After Bottas suffered this problem the mechanics had to quickly try to ensure that it didn't happen again in the event that Hamilton made another stop in the race. They tried to clean the wheel guns, but there seemingly wasn't any certainty that it would not happen again. 5/8
Later in the race Hamilton did indeed stop again, to fit softs in an attempt to gain a single point for fastest lap. This must have been an extremely tense moment in the Mercedes pit garage, but it went off without a hitch, it was a big gamble. 6/8
The F1 TV Pit Lane Channel caught another little moment. After Bottas got out of his car he was furious, and threw his glove on the floor. Rather than go into the Mercedes garage he walked into the FIA garage to take a moment to calm down before facing the team. 7/8
I decided to take a bit of a longer look at the track limits goings on at T4 during the #F1#BahrainGP yesterday. There is a bit more to this than I think some people have picked up on. /Thread.
On Friday - after Free Practice the rules relating to track limits at T4 were changed. "Advantage" in terms of 27.3 here means overtaking or defending not lap time. This document was circulated to teams and drivers. /2
Once the #BahrainGP got underway, every single driver in the field exploited the exit of Turn 4 pretty much every lap. Here you can see @yukitsunoda07 and @Charles_Leclerc doing just that. /3
