| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an improperly sized wrench, leading to cam-out and stripped hex head. | Always use a correctly sized 33mm wrench or socket to ensure full engagement with the hex head. |
| Cross-threading the screw, causing damage to both the screw and the mating threads. | Start threading the screw by hand for the first few turns to ensure proper alignment before applying any tools. |
