Detailed Engineering Specifications

Designed for demanding industrial environments, this M12 x 87mm hex head cap screw is manufactured from high-performance polycarbonate. Its superior dielectric strength (typically 16-24 kV/mm) and excellent resistance to a broad spectrum of chemicals, including many acids, bases, and solvents, make it ideal for applications where metal fasteners would corrode or interfere with electrical signals. The generous head width of 33mm provides substantial bearing surface area, distributing load effectively and minimizing stress on mating materials. Operating temperature range for polycarbonate is typically -10°C to +120°C, offering robust performance across varied conditions.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw.Use a torque wrench to adhere to recommended torque values for polycarbonate to prevent stripping or cracking.
Using in applications exceeding its temperature limits.Verify that the operating temperature of the application remains within the specified range for polycarbonate (typically -10°C to +120°C).

Common Applications

  • Chemical processing equipment assembly
  • Electrical enclosure and control panel fastening
  • Corrosion-resistant structural components

⚠️ Engineering Warnings

  • Not suitable for high-impact applications or where significant tensile or shear loads beyond material limits are expected.
  • Avoid exposure to UV radiation for prolonged periods as it can degrade polycarbonate properties over time.
