Darryl:

I would hesitate before using a "cheater bar" on 1/4X20 stainless. The torque specs are very low and do not require any mechanical advantage. If you break a bolt in a top-down situation, you can end up spending a lot of time sliding in a new bolt.

We use the Makita cordless impact drivers. I was at first dismayed that there is no torque setting -- instead the amount of time spent driving determines torque -- but we have become accustomed to the tools and they do a good job for us.

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
