Detailed Engineering Specifications

Designed for demanding industrial environments, this M19 x 116mm Hex Head Cap Screw leverages the inherent strengths of polycarbonate. Its exceptional chemical resistance makes it ideal for applications exposed to corrosive agents, while its non-conductive properties ensure electrical isolation. The substantial 32mm head width provides a large bearing surface, distributing load effectively and preventing damage to substrates. This fastener maintains its structural integrity across a wide temperature range, offering a reliable and long-lasting solution for challenging operational conditions where traditional metal fasteners would degrade or cause galvanic corrosion.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw.Tighten to the specified torque for polycarbonate, which is significantly lower than for metal fasteners, to prevent material deformation or stripping.
Using the screw in an application exceeding its temperature limits.Consult the polycarbonate material specifications for its operational temperature range and ensure it aligns with the application's environmental conditions.

Common Applications

  • Chemical processing equipment
  • Marine and offshore installations
  • Electrical enclosures and assemblies

⚠️ Engineering Warnings

  • Not suitable for high-impact or shear load applications where metal fasteners are typically required.
  • Avoid exposure to UV radiation for extended periods, as it may affect material properties over time.
