Mercedes will be unable to remove the front-right wheel nut from Valtteri Bottas' Monaco Grand Prix car until it returns to the team's UK factory this week.
Bottas was running in second position before he stopped for a scheduled tyre change mid-race, only for Mercedes to struggle to remove the tyre. It later revealed the wheel nut had been machined to the axle by the wheel gun used by its pit crew.
Mercedes technical director James Allison revealed the car left Monte Carlo with the wheel nut still attached.
