| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the polycarbonate screw, which can lead to cracking or stripping of the threads. | Use a torque wrench and adhere to the material's specified torque limits. Consult datasheets for precise values. |
| Using excessive force during installation, potentially damaging the screw head or the mating component. | Apply steady, controlled force. If resistance is encountered, check for thread alignment or obstructions. |
