| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size tool for tightening, leading to stripped hex heads. | Always use a hex socket or wrench that precisely fits the head width (32mm in this case) to ensure proper engagement and prevent damage. |
| Over-tightening, which can lead to thread stripping or fastener fracture. | Adhere to the specified torque values for the M7 thread size and material grade. If unsure, consult engineering drawings or torque charts. |
