| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped head or inadequate torque. | Utilize a 30mm wrench or socket that precisely fits the hex head. |
| Cross-threading the screw, damaging both the screw and the mating threads. | Carefully align the screw with the receiving threads and begin tightening by hand before applying tool torque. |
