Calculate Thread Minor Diameter
Introduction & Importance
Calculating the minor diameter of a thread is crucial in engineering and manufacturing. It ensures proper fit and function of threaded components…
How to Use This Calculator
- Enter the pitch of the thread in millimeters.
- Enter the number of threads per inch.
- Click ‘Calculate’.
Formula & Methodology
The formula for calculating the minor diameter (d) is:
d = P * (1 – √(n / (n * 3.14159)))
where P is the pitch and n is the threads per inch.
Real-World Examples
Example 1: A thread with a pitch of 1.25mm and 6 threads per inch has a minor diameter of 1.07mm…
Data & Statistics
| Pitch (mm) | Threads per inch | Minor Diameter (mm) |
|---|---|---|
| 1.25 | 6 | 1.07 |
| 1.5 | 8 | 1.28 |
Expert Tips
- Always use the correct pitch and threads per inch for your application.
- Consider the material and load when selecting a thread.
