Thread Identifier & Reference

Thread Identifier & Reference is a fast offline thread lookup, thread chart and CNC calculator app for machinists, engineers and CNC programmers. Search metric, inch, pipe, ACME, BSP, NPT and other thread standards, view thread profile diagrams and access practical machining calculators in one place.

Use the app to quickly search, identify and reference metric threads, inch threads, pipe threads, thread standards, thread dimensions and CNC machining data. Instead of browsing large printed charts or relying on web search in the workshop, you can find the information you need offline by thread type, size, pitch, TPI, standard or related machining parameters.

Main features:

• Thread lookup and identification

Search across 27 thread standards, including Metric, Metric Conical, UNC, UNF, UNEF, UNS, UN, British, BSW, BSF, BSPP, BSPT, NPT, NPTF, RC, ACME, Stub ACME, Trapezoidal, Buttress, Knuckle, Worm, API and more.

• Thread charts and dimensions

Reference pitch, TPI, major diameter, minor diameter, tapping drill, clearance drill and other available thread data for machining, inspection, CNC programming and mechanical design.

• Thread profile diagrams

View clear SVG thread profile diagrams for supported thread types to better understand thread geometry, form and standard-specific differences.

• CNC and machining calculators

Use practical CNC calculators and machining calculators for turning, milling and workshop setup, including cutting speed, spindle speed, feed rate, feed per tooth, feed per revolution, machining time, material removal rate, cutting power, cutting torque, depth of cut and more.

• Geometry calculators

Calculate cone dimensions, hexagon and square blanks, coordinate rotation, trigonometry values and degree conversions.

• Engineering references

Access useful workshop references such as drawing symbols, Fe-C diagram, material melting temperatures and material hardness tables.

• Offline access

Use thread charts, calculators and reference data without an internet connection — useful for workshops, production floors, maintenance work and CNC setup.

• Favorites

Save frequently used threads, calculators, charts and references for quick access.

Thread Identifier & Reference is designed for everyday use in machining, CNC programming, mechanical engineering, maintenance, workshop setup and technical education. Whether you are checking a part, identifying a thread, preparing a CNC job, selecting a thread standard, calculating cutting parameters or looking up workshop data, the app helps you find the right information faster.
