don't give enough information abot therse screw threads. On the other hand I found there some little mistakes and omissions. I asked the owener for more informations abot these scree threads but he didn't answer to me. It seems ASN is an old french standard of Aerospatiale and ASN is not an USA screw thread. Because I want to make an work about designation of USA screw thread, I want to know more information about these screw threads ( profile, dimensions, designation) from primary sorces as standards and I hope is someone who knew moreabout ASN and URS screw threads. After I'll finish I can put a complete table here if you are interested, because I want to impart my knowleges with others. The screw threads are my pasion in technical domain.
