I have a couple of already counterclockwisely tightened bolts and would like to know how much they're torqued to in the first place. I know they're torque to at least 25Nm but how much more I don't know.
I have a torque wrench (3/8" drive), and wonder if I could start with 25Nm and incrementally set (2Nm increment per step) and verify the torque by seeing when the bolt can be lossened by turning the torque wrench clockwise.
Does this method give a good enough approximation as decide by the size of each incremental step?
