| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size wrench, leading to cam-out and potential stripping of the hex head. | Always use a correctly sized socket or wrench that fully engages all six flats of the hex head to ensure maximum torque transfer and prevent damage. |
| Cross-threading the cap screw by forcing it into the mating thread. | Start threading by hand to ensure proper alignment. If resistance is felt immediately, back out and re-align before applying further force. |
