Detailed Engineering Specifications

Manufactured under strict quality controls, this M15x150mm hex head cap screw utilizes advanced polycarbonate, a thermoplastic polymer renowned for its outstanding impact resistance, high tensile strength, and excellent electrical insulation properties. The M15 designation indicates the nominal major diameter of the thread, while the 138mm length provides ample reach for various assembly requirements. The 7mm head width ensures compatibility with standard hex drivers, facilitating efficient installation. This material is inherently resistant to many chemicals and solvents, making it suitable for environments where metal fasteners would degrade or cause galvanic corrosion.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, leading to thread stripping or head deformation.Use a torque wrench set to the manufacturer's recommended torque for polycarbonate fasteners. Hand-tightening followed by a quarter turn is often sufficient.
Using metal tools that may scratch or damage the polycarbonate surface.Employ tools with appropriate coatings or ensure tools are free of sharp edges that could mar the polycarbonate.

Common Applications

  • Electrical enclosures and equipment mounting
  • Chemical processing equipment assembly
  • Medical device manufacturing
  • Corrosive environment applications

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications exceeding the thermal limits of polycarbonate (typically around 130°C).
  • Avoid prolonged exposure to UV radiation without appropriate stabilization, as it may lead to material degradation over time.
