UNF Custom Thread Type

Hi Everybody,

 

I sent in a drawing to a "Fabricator" to quote, but it got rejected and sent back because my thread wasnt specified. I specified it as UNF Series Thread and gave a basic dimension on the tube.

 

Now how can i calculate this custom thread type? UNF Standard thread only goes up to 6.000 nominal Diameter?

 

Does anybody have a custom UNF Thread calculator? Or is there a simple equation that i could use to figure this out?

 

I searched my Mech. Eng. Handbook, but im not getting results.

 

I would really appreciate this.

 

Best Regards,

Max

 

Please see attached drawing with dimensions.

(i have more drawings but i dont want to share all of it, i could email you personally if you ask)

 

Thanks!
