Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or head deformation.Always adhere to recommended torque values and use a torque wrench for precise tightening. If a torque specification is unavailable, tighten until firm and then an additional quarter turn.
Using incompatible solvents or cleaning agents that can degrade polycarbonate.Consult the material's chemical resistance chart or use mild soaps and water for cleaning. Avoid aggressive solvents like acetone or strong acids.

Common Applications

  • Chemical processing equipment
  • Marine and offshore structures
  • Electrical enclosures and insulation
  • Medical device assemblies

⚠️ Engineering Warnings

  • Polycarbonate can be susceptible to crazing or stress cracking when exposed to certain aggressive chemicals or prolonged UV radiation without appropriate additives.
  • While impact-resistant, avoid dropping or subjecting the screws to extreme point impacts that could exceed their fracture toughness.
