About this app

Thread Chart & CNC Calculators

Professional tool for machinists, engineers and CNC programmers.

The app provides a fast thread reference, practical machining calculators and engineering utilities used in everyday workshop work.

Thread Reference

Built-in thread library with common international standards:

• ANSI / ASME
• DIN
• GOST

Thread types include:

• Metric threads
• Unified threads (UNC, UNF, UNEF)
• Pipe threads
• ACME and trapezoidal threads

Each thread includes detailed parameters:

• diameter
• pitch
• threads per inch
• thread angle
• internal and external diameters
• tolerance classes

Most threads include high-resolution profile diagrams that can be zoomed for detailed inspection.

Fast Thread Search

Quickly find threads by designation:

M8
M10
G 1/2
1/2-20
UNC
UNF

Switch between metric and inch units instantly.

Ratings and reviews

Works great and tons of info. One more star if updates get made to go one step above everyone else in this space.. would be fantastic if the calculations that are auto generated are also applied to to the thread profile image. For the moment we still get the typical image with formulas (5h/8, p/8, etc), why not let the app do the rest of the calculations.. would gladly purchase a pro version if such a tool were available.

I use this app at work mostly to figure out ID and OD for machining threads. So far it's worked great. I can't tell on the rest of the app as I haven't explored or needed the rest of it.

Like the update. Very useful at work. 5 stars. I Would like to see the hole size needed for the chosen thread make a return.
