Why this exists

Every one of these numbers is already published — in a supplier PDF that opens sideways, a forum post from 2009, or a chart that answers exactly one of the four questions you have. FastenerChart puts the whole set on a single page per thread, calculated from the governing standard rather than retyped, and loads in under a second on shop wifi.
