didnt know in which section of the forum to put this question....
i have designed parts that are to be injected, and they have a buttres thread which i modeled to the male and female parts.
my problem is that i cant find anywere guidelines on what gap to model between the two threads, and what tolerances.
i have to add that i havent found this info even on iso threads or any other kind of thread.
any help will be great.
