Hinweise
Tap drill is the roughly 75% engagement rule — major diameter less 1/TPI for unified threads, less the pitch for metric — with the nearest stocked drill in brackets. Published preferred-tap charts round by convention rather than by formula and may differ by one size; for metric threads the rule is the convention and the two agree.
