Normally the degree of stud thread stretch is associated with the use of excessive air gun and/or brace and extra bar use.

A new stud will have the correct thread pitch. Due to a high degree of excessive torque levels the thread pitch will eventually stretch. The thread tester is manufactured with a precise thread pitch.
