Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screwUse a torque wrench set to the manufacturer's recommended torque specification for polycarbonate fasteners or tighten until snug and secure, but do not force.
Using incompatible tools that can scratch or damage the polycarbonate headUtilize tools with smooth, non-marring surfaces or ensure proper fit to avoid stressing the polycarbonate material during tightening.

Common Applications

  • Chemical processing equipment
  • Electrical enclosures and panels
  • Medical device assembly

⚠️ Engineering Warnings

  • Not recommended for applications requiring significant tensile strength beyond the material's capabilities.
  • Avoid prolonged exposure to UV radiation if color stability is critical, unless specifically formulated for UV resistance.
