Thread Designer
Pick a Unified inch, ISO metric or NPT thread and get its full basic profile, limits of size for the tolerance class you choose, lead angle, three-wire measurement, tap drill options, thread turning passes and a starting CNC program. Unified threads are calculated to ASME B1.1, metric threads use the ISO 965-1 tolerance tables, and pipe threads follow ASME B1.20.1.
