Agreed - but do be careful with power tools and stainless. It's very easy to
gall, particularly if you don't use anti-seize compound. Lower speeds are
helpful. I have found that once we calibrate the Makitas they are close - if
it's a critical fastener, we set the Makita ~20% under the spec and finish with
a hand torque wrench.

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.
