    ISO Tolerance Help?

    We have a few prints to quote and I have no idea what tolerances they're calling out. All I see is "h6, h7, h8, F9, f7" and things like that. What do they mean? Is there a chart somewhere that I can reference?
    Thanks, Sean

    Those tolerances are case sensitive (ID/OD).
    They are all available in Machinery's Handbook.
    Awhile back someone posted this http://www.roymech.co.uk/Useful_Tabl...ISO_LIMITS.htm link which may be of use.
    The handbook is much better and every machinist type tradesman has one.
