Because they fit?

I'd be surprised if 4mm bolts would fit - so the reason is probably to help alignment. If they had used 3mm bolts, there might be more chance of the engine being misaligned, although you'd expect the sides of the crankcase to bear on the sides of the engine mount.

Do you have a problem with 3.5mm bolts, other than them not being so common?
