Can any one help with my search for old and/or defuncked American Screwthread information via the internet?

Cheers in advance

All depends on the type of information you are looking for.

I like the sites

http://www.boltscience.com

and

http://www.fastenersources.com;

bolt science being the preferred.

There are, of course, others; so if you could be more specific, we might be able to find other sources.
