Studs vs Bolts
Actually, IMHO, the reason bolts are used instead of studs is to
keep from over loading the threads in those expensive aluminum
Porsche cylinder heads. Using a bolt as a fastener in a soft metal
is ok if there is not much load or torque put on it, but while tightening a bolt into soft threads, the first few turns of the threads generally have to take too much load and will strip out. However, with a stud, the threads are fully engaged prior to any
load being applied. When the nut is torqued, the load is evenly distributed over all the threads. Just a thought.
