Okay guys. Keep in mind in your replies that I am not a machinist and I did not sleep at the Holiday Inn last night.
The 1"7/16 x 28 tpi thread would have the minor diameter of the nut threads between 1.399" and 1.405" according to the following table:
Unified Screw Threads, Standard Series
I would like to design a nut and bolt with a non-standard thread. So that the minor diameter of the internal thread sits between 1.374" and 1.380".
I figure, to do that, I need to bring the thread size down to 1.413" from the standard 1"7/16 (1.438").
So can this be done? Will I be breaking some unwritten machinist law?
And how can I write it down on my plans so that it makes sense to a machinist?
I would write up the standard thread as - 1"7/8 x 28 tpi UN
But how would I write up my non-standard new thread? 1.413" x 28 tpi UN. Is this correct?
