I've searched to no avail. Is there a source to decode the AN specifications for screws? For example: AN526C632-6 or AN515-6-6 (these specifications from the Ercoupe parts manuals). It seems like the first group of numbers is the head style, the second group the thread (#6, 32 pitch?) and the last length in 16ths? John
