Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw, leading to potential cracking or stripping of threads.Apply torque incrementally and use a torque wrench set to the manufacturer's recommended value for polycarbonate fasteners.
Using the screw in an application exceeding its temperature or chemical resistance limits.Consult the polycarbonate material datasheet to confirm suitability for the specific operating environment before installation.

Common Applications

  • Medical equipment assemblies
  • Electrical enclosures
  • Corrosion-sensitive environments
  • Aerospace and automotive components

⚠️ Engineering Warnings

  • Not recommended for high-stress structural load-bearing applications.
  • Avoid exposure to UV radiation for extended periods without appropriate coatings, as it may degrade the polycarbonate.
  • Ensure compatibility with mating materials to prevent galvanic corrosion if used in conjunction with metals.
