One other thing when talking about using a torque wrench. There is a
general 20/80 ruse when working with them. That is, you want to use
the range from 20% of it's capacity to 80% of it's capacity. If you go
over or under that, they are a bit inaccurate. Torque wrenches are
calibrated in the center of their adjustment range.
