Full description

ThreadSpec is a fast, offline reference for screw threads — for engineers, machinists, toolmakers, and DIY. Identify and match metric and imperial threads: ISO, DIN, UNC/UNF, BSP/G. • Thread identifier by measurements (diameter, pitch, profile angle) — ranked matches. • Catalog of metric and imperial threads with filters by system and standard. • Key dimensions: diameters, pitch, tap drill, tolerances. • Clear axial-section drawing of each thread. • Engineering tools (Pro): tightening torque, bolt preload and minimum thread engagement for the chosen property class and nut material. • Favorites, millimeters/inches, light/dark themes, English/Russian. Works offline. No ads, no tracking, no accounts.
