Installation Procedure

1. Select the appropriate M6 threaded hole or nut for engagement. 2. Manually thread the polycarbonate cap screw into the mating component until snug. 3. Using a suitable hex driver (e.g., 5mm Allen key), tighten the screw to the required torque, avoiding over-tightening to prevent material deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to stripping or cracking of the threads.Use a torque wrench and adhere to the recommended torque values for M6 polycarbonate fasteners. Hand-tightening followed by a quarter-turn is often sufficient.
Using metal tools that can scratch or damage the polycarbonate surface.Employ plastic or coated hex drivers when possible. If metal drivers are necessary, exercise caution and avoid excessive force or slipping.

Common Applications

  • Electrical enclosures and control panels
  • Medical equipment assemblies
  • Corrosion-prone chemical processing environments

⚠️ Engineering Warnings

  • Polycarbonate has a lower tensile strength than most metals; do not use for structural load-bearing applications requiring high clamping forces.
  • Avoid prolonged exposure to UV radiation, as it can degrade polycarbonate over time. Consider UV-resistant grades for outdoor applications.
