| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an incorrect size drive tool, leading to cam-out and potential head damage. | Always use a properly sized socket or wrench that fully engages the hex head to ensure maximum torque transfer and prevent damage. |
| Over-tightening the screw, which can strip threads or compromise material integrity. | Tighten to the manufacturer's recommended torque specifications for the specific application and mating components. Utilize a torque wrench for precision. |
