Thread Orientation dimensioning
Thread Orientation dimensioning
(OP)
Hi,
I am to draft drawings for parts which has a male and female threads. These parts are required to be orientated using the threads, I am not aware of dimesioning threads with a tolerance to the orientation. The tolerance however is + or - 4.5 degree and both the threads are to start from 12 o clock i.e 0 degree. Are you aware of any dimensioning practise for this purpose. Need more info please let me know.

RE: Thread Orientation dimensioning
If this is not possible, locate your datums, and put a feature control frame on your hole note as you would on a regular, drilled hole. Locate the position of your threaded hole within Øx of datums A, B, etc.
This is how I would do it, unless I'm completely missing the situation.
Good luck!

RE: Thread Orientation dimensioning
I don't know of any way to do this other than an explanatory note.
I could also be completely missing the situation.

Hard to tell how to apply in your case without more detail of the part shapes involved.

RE: Thread Orientation dimensioning
Using the thread in this manner and applying a start position is practically not practical.

RE: Thread Orientation dimensioning
I persume that a text is possibly the best way. can i ask you what is a GD&T.
