| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the polycarbonate screw, leading to potential cracking or stripping of threads. | Adhere to recommended torque specifications for polycarbonate materials. Use a torque wrench for precise control and avoid excessive force. |
| Using metal tools that can scratch or damage the polycarbonate surface, compromising its aesthetic and protective qualities. | Utilize tools specifically designed for plastic fasteners or ensure that metal tools are clean and free of burrs to prevent surface damage. |
