Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or material cracking.Use a torque wrench set to the manufacturer's recommended torque limit for polycarbonate fasteners to prevent damage.
Using excessive force that exceeds the material's tensile strength.Consult engineering drawings or material specifications for appropriate load limits and avoid dynamic or shock loading beyond design parameters.

Common Applications

  • Electrical enclosures and components requiring non-conductive fasteners
  • Corrosive environments such as chemical processing or marine applications
  • Medical equipment where biocompatibility and sterilization resistance are needed

⚠️ Engineering Warnings

  • Not recommended for high-tensile strength or structural load-bearing applications.
  • Avoid exposure to extreme temperatures outside the specified operating range for polycarbonate.
