Bolt torque discussion

Bolts/studs are to be thought of as really stiff springs. You want to stretch them within the bolt/stud's elastic range. That is to say, so it will return to the unstretched length when loosened. This is the most accurate way to tighten a bolt. Next best is with a torque wrench. The torque wrench with a beam is the most accurate over time. I won't have a clicker.
