Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw, leading to stripped threads or cracking.Always use a torque wrench and adhere to manufacturer-specified torque values for polycarbonate fasteners. Hand-tighten first, then apply controlled torque.
Using standard metal torque values, which are too high for polycarbonate.Consult the material datasheet or a fastener specialist for appropriate torque specifications for polycarbonate, as it is significantly lower than for metals.

Common Applications

  • Marine and offshore equipment
  • Chemical processing plants
  • Electrical enclosures and assemblies
  • Food processing machinery
  • Medical equipment

⚠️ Engineering Warnings

  • Not suitable for applications requiring extreme tensile strength or shear resistance beyond polycarbonate's capabilities.
  • Avoid exposure to solvents or chemicals known to degrade polycarbonate.
  • Do not use in applications where significant thermal expansion or contraction could induce excessive stress on the fastener.
