I am going to have to disagree seeing as how a 10mm is too small and a 12 mm is too big I have been trying to figure this out for 3 weeks now. it is driving me crazy
again I have tried a 10mm and it is tooooooo small and a 12mm is too big. 7/16 is too small and 1/2 is too big.
this bolt has a recessed head the actual hex part is near the thread end,the one I looked at in the shop an 8mm is too small and 10mm is to big,as I stated it has to be a 9mm
