In the episode 66 of Flying lap, Scarbs was showing that they blow below the FW in completely different positions than official F1 site is showing. He point at the ends(leading edge or something like that) of the FW, not the famous slots from MS picture.
Did you see the Ferrari thread(3 big threads) on their tyre hub for tyre mounting?

You can't cross-thread this thread. And also it is faster to screw the nut. MGP use smaller threads that have bigger number of threads and are easy to cross thread.
