ThreadSpec Pro : Thread Calc

ThreadSpec Pro is a thread calculator for machinists, CNC programmers, manufacturing engineers, and inspectors. Look up common unified and metric sizes from reference tables, or calculate specials with ASME B1.1 and ISO 965-1 tolerance formulas. Built for job travelers, not for guessing on a napkin. WHAT IT DOES: • CNC thread calculator • Unified: UNC, UNF, UN, UNEF • Controlled root: UNJ / MJ • Metric coarse, fine and extra fine • External and internal classes • Plating range with pre-plate limits • Thread height, lead, helix, single/double depth • Recommended RPM using material SFM, tool, and thread size. • Job number, part number, and heat-lot fields • Save, print or share PDF report • History saved (PDF, PRINT, SHARE) SOURCE LABELS TABLE means the size was taken from the in-app reference table. CALCULATED means the size used the published tolerance formulas. Official tables still win when you are inspecting a part. HOW TO USE IT Pick series, class, and a common size, or type a special diameter and pitch. Add the plating min/max when the print calls for coating. Thread limits will be calculated accordingly. Send the report to the traveler. IMPORTANT ThreadSpec Pro is a shop helper. It is not a certified gage and not a substitute for ASME, ISO, the customer print, or your inspection department. Verify critical values before you cut or accept a part. From Quantum Coding.
