Detailed Engineering Specifications

Designed for demanding industrial environments, this M11 x 33mm hex head cap screw is precision-molded from high-grade polycarbonate. This advanced polymer exhibits superior resistance to a wide range of chemicals, solvents, and moisture, making it ideal for applications in corrosive atmospheres where traditional metal fasteners would degrade. With a nominal thread size of M11 and a head width of 16mm, it offers robust mechanical interlocking. Its inherent non-conductive nature also makes it suitable for electrical and electronic assemblies, preventing short circuits and galvanic corrosion. The material's excellent impact strength ensures durability and longevity in high-vibration or stressed conditions.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening, leading to material cracking or stripping of threads.Use a torque wrench and adhere to recommended torque values for polycarbonate fasteners. Hand-tighten first to ensure alignment before applying torque.
Using in applications exceeding the temperature or chemical resistance limits of polycarbonate.Consult the material datasheet for specific chemical and temperature compatibility before deployment. Select fasteners made from materials like PEEK or PTFE for more extreme conditions.

Common Applications

  • Chemical processing equipment assembly
  • Electrical enclosure mounting
  • Medical device fabrication
  • Food and beverage processing machinery

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding 120°C (248°F).
  • Avoid prolonged exposure to UV radiation, which can degrade polycarbonate over time without UV stabilizers.
