| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a driver that is too small or too large for the hex socket. | Always use the correctly sized hex driver to prevent cam-out and damage to the fastener head or tool. |
| Cross-threading the screw into the mating component. | Carefully start the screw by hand for the first few turns to ensure proper alignment before applying torque. |
