Thread specifications

[DennisP]

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.

Did you check in the Machinery's Handbook?

Actually, the thread is a 9/16-18UNF-2B. Thread Pitch diameter is between .5264 & .5323; minor thread diameter is between .502 & .515

Depends on the spec., MS33649 calls for 3A/3B.
