Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or head cracking.Use a torque wrench and adhere to recommended torque values for polycarbonate fasteners to prevent damage.
Using excessive force with an improperly sized hex wrench, which can round the hex head.Always use a correctly sized hex wrench that fits snugly into the screw head to ensure proper engagement and prevent damage.

Common Applications

  • Electrical enclosures and equipment assembly
  • Corrosive chemical processing environments
  • Lightweight structural components and panels

⚠️ Engineering Warnings

  • Not intended for high-temperature applications exceeding the material's continuous use temperature.
