Assuming they are high tensile bolts, and they should be, go to your local bolt supplier with a sample and ask them what the max torque setting is for the bolt size in question.
they will have a chart on the wall

I am assuming it will be Grade 8 bolt and probably M10, if so the torque setting will be something in the order of 45ftlb in steel/iron or 35ftlb in Aluminium.
I would just do them up "tight" (until it hurts your hand) with one hand and a 8" long ring spanner... will be close enough
most important thing is they are all about the same torque as each other.
