Quote: How are you going to differentiate from "breakaway torque" (what I assume you are measuring when you remove a fastener) and "installed torque" (which is what the factory tightened the fastener too)???? They are most certainly two different values!
We will not be calculating the breakaway torque. The torque will be calculated after the parts are void of ALL oxidation and then reassembled. The thread count and nut configuration will be compared to the "before" documentation. That is why I mentioned the pre-stress condition that occurs on parts when they are originally assembled.
