Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to stripping of plastic threads or cracking of the polycarbonate.Use a torque wrench set to the manufacturer's recommended specification for polycarbonate fasteners. Hand-tighten initially and then apply torque gradually.
Using metal tools that can scratch or mar the surface of the polycarbonate screw head.Employ tools made from softer materials or ensure they are clean and free of metal burrs before use.

Common Applications

  • Electrical enclosures and equipment
  • Marine and chemical processing environments
  • Corrosive industrial settings

⚠️ Engineering Warnings

  • Do not exceed the maximum recommended torque for polycarbonate fasteners, as this can lead to material deformation or failure.
  • Avoid exposure to strong solvents or aggressive chemicals that may degrade polycarbonate.
