    Where did this come from? It isn't a common bolt size.

    Of course it is!

    It's American National Fine Thread.

    Is "Fine" another word for posh thread?
    :)

    Only if you use them in a suit.

    You are right. Looks like the little quick reference card isn't
    matching up with MH.

    Muggs,

    Did some more looking. It turns out this is an odd situation.
    Machinery's Handbook say 12tpi is the standard fine thread as does SW,
    but in bolt catalogs only 14tpi is available for 1 inch bolts.

    Interesting. Even my old Starrett decimal equivalents and tap drill
    chart shows only 1-8 and 1-12. Looking at tool catalogs they have 1-8,
    1-12 and 1-14 taps stocked.
    HHMMMMMMMMM!

    SW got me a solution. It is posted on the forum under Toolbox.
