Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or head deformation.Use a torque wrench and adhere to the recommended torque specifications for polycarbonate fasteners. Hand-tightening followed by a slight turn is often sufficient.
Using metal washers directly against the polycarbonate head, causing stress concentration and potential cracking.Employ plastic washers or broad-faced washers specifically designed for use with plastic components to distribute load evenly.

Common Applications

  • Electrical enclosures and equipment assembly
  • Marine and coastal environments where corrosion is a concern
  • Food processing machinery and medical devices requiring chemical resistance

⚠️ Engineering Warnings

  • Avoid use in applications exceeding the temperature limits of polycarbonate (typically around 120°C / 248°F).
  • Do not use in high-impact applications where the material's inherent brittleness at low temperatures could be a factor.
