Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw, leading to thread stripping or head cracking.Apply torque conservatively, using a torque wrench if precise control is required, and stop when the screw feels snug.
Using metal tools that may scratch or damage the polycarbonate surface.Utilize plastic or coated tools where possible, or exercise extreme care to avoid marring the fastener's finish.

Common Applications

  • Electrical enclosures and equipment
  • Medical device assembly
  • Corrosive chemical processing equipment

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications above 120°C (248°F).
  • Avoid prolonged exposure to UV radiation, which can degrade polycarbonate over time.
