Torque values clean http://www.engineersedge.com/material_science/torque_values_stainless_steel_13353.htm
The Locktite Corporation Technical staff recommends: Decrease the specified torque values by 20% when using the Locktite Purple, Blue or Red on dry bolt specs!

There is a different schedule for torquing dry threads and dressed
threads- higher torque for dry. This might be the reason for multiple
numbers - different answers for different questions.

You may not get an accurate torque on the keel nuts unless you are
dealing with clean threads and a nut that turns freely against a clean
surface. Be sure it isn't frozen by loosening the target nut first and
inspecting the threads and giving the threads a shot of drylube or
Moly-kote or other anti-galling grease before going for the actual
torque value. Then move on to the next. You don't want to risk galling
the threads, so some lubrication might be important. BUT I DON'T KNOW
for sure.

March 24th. I contacted Catalina directly on the Keel Bolt torque.
Catalina told me the bolts should be torqued to 100 ft lbs. I was
wondering where the 235 ft lbs number came from?
