| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect torque values, leading to over-tightening or under-tightening. | Always consult the appropriate engineering specifications or torque charts for the specific application and materials being joined. |
| Cross-threading the fastener due to improper alignment during installation. | Carefully align the screw with the mating thread and rotate it by hand for the first few turns to ensure it starts correctly. |
