| # Bolt Torque Calculator |
|
|
| **Author:** Sebastian Andreu |
| **Course:** 24679 - Designing and Deploying AI/ML Systems |
|
|
| This app calculates the torque required to tighten a bolt to a target preload using first-principles engineering formulas. |
| The interface allows users to input or select: |
| - Bolt diameter [mm] |
| - Target preload [N] |
| - Thread pitch [mm] |
| - Bolt material and lubrication (for estimating thread friction coefficient) |
| - Nut/under-head material and lubrication (for estimating friction under the head) |
| - Optional head diameter [mm] |
|
|
| The model outputs the required torque in **Nm** along with a natural language explanation of the result for non-experts. |

|
| ## How to Use |
| 1. Enter the bolt geometry and preload values. |
| 2. Select the bolt and nut/head materials and lubrication type. |
| 3. Optionally specify the head diameter; leave blank to use default (1.5×bolt diameter). |
| 4. Click **Compute** to see the torque and an easy-to-understand explanation. |
