| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an under-torqued fastener, leading to potential loosening under vibration. | Always adhere to the recommended torque specifications for the application to ensure a secure connection. |
| Cross-threading the screw, which damages both the screw and the receiving threads. | Start threading the screw by hand to ensure it engages properly before using a tool. If resistance is met, back it out and try again. |
