| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the screw, which can lead to stripping of the threads or cracking of the polycarbonate head. | Always adhere to recommended torque specifications for polycarbonate fasteners. Use a torque wrench for precise control. |
| Using metal tools that can scratch or damage the polycarbonate surface, compromising its aesthetic and potentially its integrity. | Employ tools with plastic or rubber coatings, or use extreme care to avoid contact between metal tools and the polycarbonate surface. |
