Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this M23 x 40mm polycarbonate hex head cap screw features a 17mm head width. Polycarbonate provides superior chemical resistance to acids, alkalis, and solvents, making it ideal for food processing, medical equipment, and marine applications where traditional metal fasteners would corrode. Its inherent non-conductive properties are critical for electrical insulation and preventing galvanic corrosion. The material's excellent impact strength ensures durability in vibration-prone settings.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening polycarbonate fastenersUse a torque wrench and consult material specifications for recommended torque values. Avoid excessive force, which can strip threads or crack the fastener.
Using in high-temperature environments exceeding polycarbonate's thermal limitsVerify the operating temperature range of polycarbonate and select an alternative material if the application exceeds these limits.

Common Applications

  • Chemical processing equipment
  • Medical device assembly
  • Marine and offshore installations
  • Electrical enclosures
  • Food and beverage industry machinery

⚠️ Engineering Warnings

  • Avoid use in environments with high UV exposure without UV stabilization, as it can lead to degradation.
  • Polycarbonate has a lower temperature resistance compared to some metals; ensure operating temperatures are within specified limits.
