You've got to be kidding me. You can read Sikorsky tech pubs or FAA hardware study guides all day long and will never find reference one to "stretching" a bolt. It's all TQ values.
As far as "Yikes, I sure hope you are not licenced to actually sign off on anything

What part of A&P confused you?

Two points:
(1) But that's all TQ
IS! You are simply stretching a bolt to a prescribed a value! And on really critical applications it is taken one step further to include special grease and a rotational limit in which you must get the prescribed TQ.
(2) Re your A&P - my point exactly. Where did you get it - out of a popcorn box?
