| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped head. | Always use a correctly sized 13mm wrench or socket for proper engagement and torque application. |
| Over-tightening the screw, which can strip threads or compromise material integrity. | Adhere to the specified torque values for the application to avoid over-stressing the fastener and mating components. |
| Cross-threading the screw during installation. | Start threading by hand to ensure proper alignment before applying any torque with a tool. |
