| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using undersized tooling for tightening. | Always use a wrench that properly fits the 15mm head width to ensure even torque distribution and prevent head stripping. |
| Over-tightening the fastener, leading to thread damage or material deformation. | Adhere to the specified torque values for the M16 size and material to prevent fastener failure and damage to the assembled components. |
