Can someone tell me the specification - dimensions, thread size and steel spec - of Model A con rod big end cap bolts, please? My books give info on torque settings, nut spec etc but, strangely, not the actual size. I'm too lazy to take the sump off just to look! Thanks, Giles
 
The "bolt" thread is part of the rod, forged one piece with the rod, made out of the same piece of metal as the rod that is why you only found specs for the nuts

i have a print of the rod,probably one of several pages, it is fuzzy on the edges, can't read if it says type of steel,, big end weight 512 + - 1 gram, small end 198 += 1 gram, center to center 7.498-7.502",
