- TL;DR Summary
- I want to determine by calculations how many force can be applied to a Bolt-Nut connection. Needed to now what input and formulas are necessary for this.

Hello!

From below sketch, I determined the following assumptions:

- Bolt/Nut: M12, Steel 10.9

- The nut is fixed

How can I calculate the ultimate force before the bolt will damage the nut? I can imagine the flanges of the threads will break. In documentation I have read about tension surface (At), Shear stress surface (Ath) and maximum shear stress (
