Installation Procedure

1. Select appropriate torque wrench or driver with the correct bit size for the M5 hex head. 2. Align the screw with the pre-drilled or tapped hole in the mating components. 3. Thread the screw in by hand for the initial few turns to prevent cross-threading. 4. Apply gradual, consistent torque to achieve the desired clamping force, avoiding over-tightening, especially in softer materials.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, which can lead to cracking or stripping of the threads.Use a torque wrench set to the manufacturer's recommended torque values for polycarbonate fasteners or apply a snug fit without excessive force, especially when fastening into plastic components.
Using solvents or cleaning agents incompatible with polycarbonate, which can cause material degradation or embrittlement.Consult the polycarbonate material data sheet for a list of compatible cleaning agents and solvents. Opt for mild detergents or isopropyl alcohol for cleaning.

Common Applications

  • Corrosive chemical processing equipment
  • Electrical enclosures and control panels
  • Medical device assemblies
  • Marine and offshore equipment
  • Food processing machinery

⚠️ Engineering Warnings

  • Not intended for structural load-bearing applications where high tensile or shear strength is critical.
  • Avoid prolonged exposure to strong UV radiation without protective coatings if long-term outdoor use is planned, although this grade offers good UV resistance.
  • Ensure compatibility with mating materials to prevent galvanic corrosion or material incompatibility issues.
