Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening causing stripping or cracking of the polycarbonate threads.Use a torque wrench set to the manufacturer's recommended torque for polycarbonate fasteners to avoid over-stressing the material.
Using excessive force with an impact wrench, leading to premature failure.Hand-tighten only or use a low-torque, variable-speed drill with a clutch setting to prevent damage to the polycarbonate.

Common Applications

  • Chemical processing equipment
  • Marine and offshore installations
  • Electronics and electrical enclosures
  • Food processing machinery
  • Medical device assemblies

⚠️ Engineering Warnings

  • Not recommended for applications exceeding the material's temperature or load limits.
  • Avoid exposure to strong UV radiation over extended periods unless specifically rated for such conditions.
