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

[Kurt Albershardt]

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.
