Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive torque, leading to thread stripping or head deformation.Apply appropriate torque based on the nylon's tensile strength and the application's requirements. Refer to torque charts if available or use a torque wrench for precision.
Using the wrong size hex wrench, potentially damaging the head or failing to achieve proper tightening.Ensure the hex wrench or socket precisely matches the 23mm head width of the cap screw.

Common Applications

  • Electrical enclosures and control panels
  • Corrosive chemical processing equipment
  • Lightweight structural assemblies

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding the thermal limits of nylon.
  • Avoid using in structural applications requiring extreme load-bearing capacity where metal fasteners are specified.
