Hey:
I get to add my two cents worth(all its worth). Been in industries for 38 years with numerous engineers with stud and bolts. Bill is correct on his analysis of the advantages of studs.The fine threads at the top (7/16-20) does provide more clamp force than a 7/16 bolt. At one time I calculated the additional force but too much time and too many beers have gone over the damn. This is one of the reasons that we profisise studs. Also we never tighten the shoulder of the stud into the hole. We use conservative amount of blue Loctite and install stud to shoulder and back off 1/4 turn. We then install head and torque to 40 ft lbs and let set over night ant then disassemble. This forces the stud to be held to the top of the threads and is straight. There are other advantages to studs but yall get the crux of my intent. Don't get me wrong I do not profess to be and expert. Far from. Just our way and nothing more.
sorry for the dissertation
