I've been pretty lucky so far but at some point my luck will run out. My plans are to purchase all brand new nuts and bolts, clean the hub and sprocket and torque everything as it should be. I'm concerned that the first time the bolts loosened, it 'opened' up the holes in the hub and this may be the cause of the shearing of the last bolts. If this is the case, is there a 'fix' without having to buy a new hub?
Thanks in advance!

Most bolting systems are designed to hold by clamping force making friction between the two parts rather than by resisting shearing forces. I would try the oversize bolts first and get proper torque on them. Use the torque spec. for the bigger bolts, as you shouldn't deform the other parts.
