Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the polycarbonate screw, leading to thread stripping or head deformation.Use a torque wrench set to the recommended torque specification for polycarbonate fasteners of this size and application.
Using excessive force during installation, which can fracture the polycarbonate.Thread the screw by hand initially, and only apply measured torque with a tool, respecting the material's properties.

Common Applications

  • Electrical enclosures and equipment assembly
  • Medical device manufacturing
