Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw, which can lead to cracking or stripping of the threads.Apply firm but gentle torque. Use a torque wrench set to the appropriate specification for polycarbonate fasteners to ensure proper seating without damage.
Using excessive force with an incompatible tool, potentially damaging the hex head.Use a properly sized metric hex socket or wrench that fits the 9mm head width snugly. Ensure the tool is in good condition and not worn.

Common Applications

  • Electrical enclosures and equipment mounting
  • Medical device assembly
  • Food processing machinery components
  • Corrosion-resistant industrial fixtures

⚠️ Engineering Warnings

  • Avoid exposure to temperatures exceeding the material's thermal limits, as this can compromise structural integrity.
  • Do not use in applications where extreme impact or abrasive forces are anticipated without proper protective measures or alternative material selection.
