Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw, leading to potential material deformation or fracture.Apply torque gradually and stop when the screw is snug and secure. Utilize a torque wrench for precise control if critical.
Using a metal wrench that could scratch or damage the polycarbonate head.Employ a wrench made of a softer material, such as nylon or rubber-coated, or use extreme care to prevent surface damage.

Common Applications

  • Electrical enclosures and equipment assembly
  • Medical device manufacturing
  • Corrosive chemical processing environments
  • Lightweight structural assemblies

⚠️ Engineering Warnings

  • Not intended for high-temperature applications where polycarbonate properties may degrade.
  • Avoid exposure to strong UV radiation for extended periods, which can cause material embrittlement over time.
