Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to stripping or cracking of the polycarbonate threads.Use a torque wrench and adhere to the recommended torque specifications for polycarbonate fasteners. If a torque wrench is unavailable, tighten until snug and then an additional 1/8 to 1/4 turn.
Using metal tools that can scratch or damage the polycarbonate surface.Employ plastic or nylon-coated wrenches to prevent surface damage and maintain the aesthetic integrity and chemical resistance of the screw.

Common Applications

  • Chemical processing equipment assembly
  • Electrical enclosures and control panels
  • Food and beverage processing machinery

⚠️ Engineering Warnings

  • Maximum operating temperature for polycarbonate is typically 115°C (239°F). Exceeding this can degrade material properties.
  • While impact-resistant, polycarbonate can be susceptible to stress cracking in the presence of certain aggressive solvents. Consult a material compatibility chart.
