Threads (sizes, tolerances, calculations)

Master thread calculations and machining specifications with Threads (sizes, tolerances, calculations)—the professional reference tool built for machinists, engineers, and CNC programmers who need fast, accurate information on the shop floor.

Access a comprehensive thread reference library instantly. The app includes common international standards—ANSI/ASME, DIN, and GOST—covering metric threads, unified threads (UNC, UNF, UNEF), pipe threads, ACME, and trapezoidal threads. Every thread entry displays critical parameters: diameter, pitch, threads per inch, thread angle, internal and external diameters, and tolerance classes. High-resolution profile diagrams are included for most threads, with zoom capability for detailed inspection when precision matters.

Find the thread you need in seconds. Search by common designation—M8, M10, G 1/2, 1/2-20, UNC, UNF—and toggle between metric and inch units instantly without navigating menus. This speed matters when you're working against a deadline or troubleshooting a job on the machine.

Perform essential machining calculations without leaving the app. Turning operations are covered with cutting speed, spindle speed, cutting power, and torque calculations. Milling tasks benefit from feed rate, feed per tooth, cutting speed, and machining time tools. These utilities eliminate the need for separate calculators or manual lookup tables, keeping your workflow efficient and reducing calculation errors.

Leverage specialized engineering tools for geometry and trigonometry tasks. The cone calculator, hexagon calculator, coordinate rotation, and trigonometry utilities handle the mathematical heavy lifting for layout work, tool design, and part programming.

Designed for real workshop conditions, Threads (sizes, tolerances, calculations) works entirely offline—no internet required, no waiting for cloud sync. The clean interface prioritizes function over decoration, and every tool is optimized for fast access. Whether you're setting up a job, checking specifications, or solving a calculation problem, this app delivers practical solutions for everyday machining tasks without unnecessary complexity.
