| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a worn or incorrect size wrench, leading to cam-out and fastener head damage. | Always use a properly sized, good condition hex wrench or socket to ensure full engagement with the fastener head. |
| Over-tightening the fastener, which can strip threads or lead to material fatigue. | Tighten to the manufacturer's recommended torque specification for the specific application and materials involved. |
