[RE-wrenches] Need help to get power torque wrench

[Darryl Thayer]

Hi all, I need advice
I am soon starting a 1000 module system, uning top down mounts, What power tools will tighten to torque specification?  I will want to tighten each SS 1/4" nut on bolt to proper specs.  This is about 2000 bolts, so i want a power tool, either air or battery electric, or electric that will tighten to specification.  

Thanks Darryl
