| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force and stripping threads on the mating component. | Always consult torque charts for the specific application and material, and apply steady, controlled pressure during tightening. |
| Not fully engaging the screw into the threaded hole, leading to insufficient grip. | Ensure the full 41mm length of the screw is engaged with the mating threads for optimal load distribution and security. |
