Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening, leading to thread stripping or cracking of the polycarbonate.Utilize a torque wrench set to the recommended specification for polycarbonate fasteners to ensure proper tension without damage.
Using excessive force with impact tools, which can fracture the screw head or threads.Hand-tighten initially, then use a manual wrench or a low-torque setting on a powered driver. Avoid impact wrenches entirely.

Common Applications

  • Electrical enclosures and control panels
  • Marine and corrosive environments
  • Medical equipment assembly

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding 80°C (176°F).
  • Avoid exposure to strong solvents that may degrade polycarbonate.
