I need to know the dimensions for a 9/16 - 18 SAE Port Thread. Where can I find this info or, does anyone have the dimensions, such as Major, Minor and Pitch diameters, any lead taper, etc? Thanks in advance for the help!

Is this a straight thread tube fitting boss? If so the thread is 9/16-18UNF-3B.
