# 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. |
