How do you perform a "Stretch Test" on a Stud? You get him all worked up and hang him from a tree by his stud! Or in the case of engines and not machinists, you pretty much cannot! Sure there are some methods. Some say that when torqueing the stud nut down the stud will lift up "X" amount. Then there is the Torque method and Angular Rotation method. Two outa three ain't bad!
