| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped head or inadequate torque. | Always use a wrench or socket that precisely fits the hex head to ensure proper engagement and torque transfer. |
| Over-tightening, which can cause thread damage or material fatigue. | Refer to torque specifications for the application and material, and use a torque wrench for accurate tightening. |
