Detailed Engineering Specifications

Built to exacting engineering tolerances, this M19 x 36mm hex head cap screw features a 16mm head width, ensuring precise fitment and reliable torque transfer. Fabricated from advanced polycarbonate, it offers superior resistance to a broad spectrum of chemicals, solvents, and UV radiation, while maintaining a high tensile strength and low coefficient of friction. Its non-conductive nature makes it an excellent choice for electrical enclosures and applications where galvanic corrosion is a concern. The inherent toughness of polycarbonate also provides excellent impact resistance, making it suitable for dynamic loading scenarios.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, leading to material cracking or stripping of threads.Use a torque wrench set to the manufacturer's recommended specification for polycarbonate fasteners, or apply firm but controlled pressure during tightening.
Using metal tools that can scratch or damage the polycarbonate head.Employ plastic or composite wrenches/sockets, or ensure metal tools have smooth, non-marring surfaces.

Common Applications

  • Chemical processing equipment
  • Medical device assembly
  • Electrical enclosures and insulation

⚠️ Engineering Warnings

  • Not recommended for applications exceeding the material's specified temperature limits.
  • Avoid prolonged exposure to highly abrasive materials which could degrade the polycarbonate surface.
