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.
