| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped head or improper torque. | Always use a wrench or socket that precisely fits the 32mm head width. |
| Cross-threading the screw during installation, damaging both the screw and the receiving thread. | Start threading by hand to ensure proper alignment before applying torque. |
