Trying to figure Minor ø on Female Rolled Threads
We had an issue where the some 1/4-20 threads that were nonexistent in some parts. The parts would be acceptable to a go/no-go gage, but with so little thread engagement, the parts come apart when assembled and put under pressure. The threads are rolled, and all I am able to find is where the hole diameter should be to tap the hole. Is there a standard for minor diameter of a rolled thread????
thanks for any and all help!
