^ya, many buy metric all thread, and use that cut to length. Measure twice, cut once.
I have custom made some studs for a few people. Once set was made from stainless, the other set some time later was made from a very tough grade of carbon steel. (the name and RF slips my mind at the moment.)
They were spun on a lathe, and the ends were threaded for the right pitch needed. We went a step further and made the ends to have a hex head allen head insert for them, for threading them in, that way you can pre torque them to 10 ft. lbs. so you knew they were seated, then add all your gaskets, IC and supercharger, and torque the nuts on the tops to speck.
They cost a pretty penny because they were custom one off's, but they were pretty damn *****ing when done.
Many go the all thread route, cause most can handle the use of a measuring tape, a hack saw, and a bench grinder, and its waaaaaaaaaay cheaper.
