More precise than my "elbow pop" and for the larger ones "shoulder pop". Guess I'm getting old.

Naturally, the torque spec depends on the dia. of the stud and the material it's made of. A common spec for 1/2-20 studs is 77 lb ft torque when a grade 5 stud is used.

Those are probably Grade 8's... For a 1/2-20, torque is 92 ft-lbs.
