May 1, 2009 #2 BiPolarMoment Mechanical Mar 28, 2006 625 My googling has netted me very little to answer your question. I've seen one company (http://nookindustries.com/acme/AcmeAvailability.cfm) selling a 6" diameter thread (1.5" TPI) but I don't know that it is a "norm". Otherwise I see nothing but 5" at the upper end elsewhere. If it's specified anywhere, I'd imagine it's in ASME B1.5 which I don't have, sorry. Upvote 0 Downvote
