Torque values are a bit of a minefield, they are normally quoted for a perfectly dry thread. The whole idea is to get the proper clamping force which equates to the amount of tension in a fastener ( in critical applications bolts are 'stretched' a known amount by the torque ) - In critical applications in industry I remember having bolts with a hole down the centre with a rod in it, the bolt was tightened until the rod was 'nipped' in the hole ( as the bolt stretched the hole in centre became smaller ), this showed the bold had stretched the right amount. Another method often used is 'torque angle' tightening.
