O.E.M.s have specifications on fasteners such as this to be followed to the letter by the nut runner guns used on assembly lines (robotic as well as human operators. Specs are for flat counts and something called 'prevailing torque'. Even though the nut runner traveled so many flats, the last torque reading must be within an acceptable range. Likewise, a gun reaching a final torque level must have acumulated so many flats. This addresses misthreaded nuts and studs as well as missing parts (as in: you ran a wheel stud but the wheel is not in correct position). Don't laugh, it's happened. For example if the paint line throws down the wrong color or type of wheel, the build manifest will put a hold on the chassis line. But if that line had started, there will be no wheel. So, to make sure all 4 wheels are correct, you check the torque (wheel is there, and the flats, wheel is there and not misthreaded). Sure, none of you folks would ever build a FSAE car and forget to put a wheel on, but when you make a thousand per day, shit happens.

And, you seem to be having trouble KEEPING A WHEEL ON ???)
