| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to head stripping. | Always use a properly sized 19mm socket or wrench to avoid damaging the hex head. |
| Cross-threading the screw, causing damage to both the screw and the receiving thread. | Start threading the screw by hand to ensure it is properly aligned before applying any torque. |
| Over-tightening the screw, which can lead to thread damage or fastener failure. | Adhere to the recommended torque specifications for the application to prevent over-stressing the fastener. |
