Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nylon screw, which can strip threads or fracture the head.Use a torque wrench and adhere to the recommended torque specifications for nylon fasteners.
Using in applications requiring high tensile strength or load-bearing capacity beyond nylon's capabilities.Select fasteners with appropriate material properties (e.g., steel) for high-stress applications.

Common Applications

  • Electrical enclosures and equipment
  • Corrosive environments (chemical processing, marine)
  • Lightweight assemblies and instrumentation

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding nylon's thermal limits.
  • Avoid use in applications requiring significant shear or tensile strength unless thoroughly evaluated.
