Detailed Engineering Specifications

Engineered for reliability and performance, this M22 x 19mm hex head cap screw features a precisely manufactured M22 thread size and a 19mm length, ensuring secure and consistent fastening. The head width measures 18mm, providing ample surface area for torque application. Constructed from high-grade polycarbonate, it exhibits superior resistance to a wide range of chemicals, solvents, and UV radiation. Its non-conductive properties make it ideal for applications where electrical isolation is critical. The inherent toughness and impact resistance of polycarbonate ensure long-term durability in industrial and outdoor settings, contributing to reduced maintenance and replacement costs.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, leading to stripping of the polycarbonate threads.Always adhere to recommended torque specifications. If unsure, use a torque wrench and start with a lower setting, gradually increasing if necessary.
Using the screw in an application exceeding its load-bearing or temperature limits.Consult the material datasheet for specific load and temperature capabilities. Select fasteners appropriate for the intended operational environment.

Common Applications

  • Corrosive chemical processing equipment
  • Electrical enclosures and control panels
  • Water treatment facilities and marine environments

⚠️ Engineering Warnings
