   According to my Copper State Bolt & Nut handbook, M12 bolts come
in two threads: coarse - 1.75 and fine - 1.5.  I'd send you to their web
site, but it appears they are redesigning it.

I need to know the size of the larger bolt that goes thru the oil pan and was part of the original engine mount in a car. I think it may be 12mm x1.25 but can' find any that size. The original one I have are too long and if you would cut them off all the threads would be lost.
