Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to thread stripping or material deformation.Utilize a torque wrench set to the recommended torque value for polycarbonate fasteners to prevent damage.
Using in applications with extreme temperatures beyond polycarbonate's rating.Verify the operating temperature range of polycarbonate against the application's environmental conditions.

Common Applications

  • Corrosion-resistant equipment assembly
  • Electrical enclosures and components
  • Marine and offshore installations

⚠️ Engineering Warnings

  • Not suitable for structural load-bearing applications requiring metal fastener strength.
