| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size tool, leading to head stripping. | Always use a properly sized socket or wrench that fits snugly onto the hex head. |
| Cross-threading the screw, damaging both the screw and the mating threads. | Start threading the screw by hand to ensure it engages with the threads correctly before applying any torque. |
| Over-tightening the screw, which can lead to thread deformation or failure. | Tighten the screw to the recommended torque specification for the application or until snug, then stop. Consider using a torque wrench for precision. |
