Thank you for your reply, I can't find anything on finishes of threads. Our customer wants perfect threads so I was looking to see if there was some kind of spec on the finishes of threads.
I am looking for any spec that points out any non conformance of threads, we do a lot of Aero Space work and the threads are a big issue. We want to see what is considered non conformance of a thread, like nicks, scratches and finishes.
