Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nylon screw.Use a torque wrench set to the appropriate low torque value for nylon to prevent stripping or cracking.
Using in high-load structural applications.Verify the shear and tensile strength of nylon is sufficient for the intended load. Consider metallic fasteners for critical structural integrity.

Common Applications

  • Electrical enclosures and panel mounting
  • Automotive interior components
  • Marine and boating equipment assembly

⚠️ Engineering Warnings

  • Not suitable for high-tensile or high-shear strength applications.
  • Avoid prolonged exposure to UV radiation which can degrade nylon over time.
