| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening can strip threads or deform the mating component. | Always refer to torque specifications for the specific application and materials being joined. Use a calibrated torque wrench. |
| Using the wrong size wrench can round off the hex head, making removal difficult. | Select a wrench or socket that fits snugly onto the hex head without excessive play. |
