Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nylon screw.Use a torque wrench set to the manufacturer's recommended torque value for nylon fasteners to prevent thread stripping or head stripping.
Using in applications exceeding the material's temperature rating.Verify the operating temperature of the application and ensure it remains within the -40°C to +100°C range of Nylon 6/6.

Common Applications

  • Chemical processing equipment
  • Electrical enclosures and grounding systems
  • Marine and offshore components

⚠️ Engineering Warnings

  • Not suitable for high-impact or shear load applications where metallic strength is critical.
  • Avoid prolonged exposure to UV radiation, which can degrade nylon material over time. Consider UV-stabilized variants if necessary.
