Front shocks - Bar Pin bolt size/pitch/length

I am about to pull the shocks out of my Jeep again tomorrow and I want to be prepared in case any bolts break or I need longer ones down on the bar pins. Not likely since its all been torn apart less than 6 months ago, but might as well be ready just in case.

Question is what is the size and length and thread pitch on the 4 bar pin bolts at the bottom?
