I'm no ME and don't portray one on TV, and can only add that the Groco IBVF flanges I just installed on my boat are designed to mate to Groco thru-hulls and IIRC they accept about 6 turns before topping out. Same for the Groco ball valves that are designed to fit the IBVF flanges on top. About 6 turns.

I don't know squat about the technical specifications of the situation, but trust that Groco does and that this thread fit is sufficient for full strength in their bronze. Just a data point for consideration.
