Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to thread stripping or cracking of the polycarbonate head.Use a torque wrench set to the manufacturer's recommended torque specification for polycarbonate fasteners. Apply force gradually and avoid sudden jerks.
Using metal tools that can scratch or damage the polycarbonate surface.Employ plastic or coated tools specifically designed for use with plastics to maintain the surface integrity of the screw.

Common Applications

  • Chemical processing equipment
  • Food and beverage machinery
  • Marine and offshore installations
  • Electrical enclosures and components

⚠️ Engineering Warnings

  • Avoid prolonged exposure to UV radiation, which can degrade polycarbonate over time.
  • Do not use in applications exceeding the material's maximum temperature rating.
