Sorry about this, I just get mad when people sneer at the facts because it is not what they are used to / have been told in the past / or just don't want to believe it. E.G. Drivers vs. bicycle right to the road.

HOWEVER, I am giving you the facts about torque calculations. They are very rough approximations. When true bolt tensions are needed in my industry, we stretch the bolt hydraulically, and then run the nut down snug.

Torques probably get the required tension most of the time, so go ahead and use the wrench. I was just pointing out that you shouldn't worry about a 6% error, because the calculation used to get the torque probably has like 30-50% error because it is an approximate calculation using approximate values in the first place. This is especially true for small torques, less so for larger torques, like I said earlier.

I am just trying to give people perspective, so please don't sneer. If you do this stuff for a living and have facts, then please let me know.
