| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size hex key or socket, leading to head damage or incomplete tightening. | Always verify the correct hex key or socket size for the M5 head before installation. |
| Cross-threading the screw, which can damage both the screw and the mating part. | Start threading by hand to ensure proper alignment before applying any torque. |
