| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to stripped head or incomplete tightening. | Always use a wrench or socket that precisely fits the hex head to ensure optimal force application and prevent damage. |
| Cross-threading the screw by forcing it during initial engagement. | Gently hand-thread the screw for the first few turns to ensure it is properly aligned with the mating threads before applying any tool. |
