A cordless drill with a 10 mm socket is a great help here.
One potentially life-threatening error in the above. Leaving the plates in place can keep the circuit live without the bolts. The bolts snug the plate to the stick, but it there may be enough contact to form a circuit without the bolts.

Be careful.
