      OK, so you got your wrench calibrated within a gnats eyelash.  Are you 
      actually measuring the torque correctly?
      
      First, measure the drag the nut / bolt combination exerts.  Those nuts with 
      the inserts will give you a few inch pounds.  And the wood on my wood prop 
      initially gave several pounds.
      
      Then add the drag to the specified torque and use that number for your 
      torque setting.

      The torque on the wood prop was to give the correct amount of crush on the
      wood 
      at that torque not to have that added to it.Consult the correct torque
      tables, they will
       give it to you and don't just add to things because one thinks that is
      right as that 
       could over torque the bolt. There are specific torque's for certain grade
      of bolt
       or for certain parts never exceed those values.
