Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or head deformation.Use a torque wrench and adhere to recommended torque values for polycarbonate fasteners. Avoid excessive force.
Using the wrong size tool for the hex head, resulting in cam-out and damage to the fastener.Always use a correctly sized socket or wrench that fits snugly on the 24mm hex head.

Common Applications

  • Electrical enclosures and equipment assembly
  • Corrosive chemical processing environments
  • Medical device manufacturing

⚠️ Engineering Warnings

  • Not suitable for applications requiring high tensile or shear strength exceeding polycarbonate's capabilities.
  • May degrade under prolonged exposure to certain aggressive solvents or high temperatures. Consult material compatibility charts.
