Ever wonder how those NASCAR guys can get the lug nuts on so quick?

Well I have been a mechanic my whole life....so I know the ins and outs of tools etc. etc...I always wondered how they get on those lug nuts so fast in pit stops....I knew it had to be something with the socket......Well, my nephew started pitting for NASCAR in all 4 series......ARCA, Truck, XFINITY, and Cup.....He went to school for it....Yeah, they actually have a pit school.......Anyway, they glue the lug nuts to the wheels ahead of time which most everybody knows......They are hexagon lug nuts (six sided for us non math people) .......But take a look at the socket they use......not hex shaped like a 6 point......or even 12 point.......which would get on quicker......look at the shape it is like a flower.....it can find the lug nut in any position...except if you would hit point to point.......now yes, there is tons of slop on the nut but as long as it catches on the high spots it will tighten.....And they use new lug nuts every time so even though it is hard on the points of the hex nuts as long as they tighten and loosen one time, that is all they need....I thought that was interesting.....I got this shot of their socket when a lug nut stood up on end and ruined a pit stop.....
