Detailed Engineering Specifications

A proven choice for industrial professionals, this M10 x 39mm Hex Head Cap Screw features a robust polycarbonate construction, offering superior resistance to corrosion, chemicals, and impact compared to traditional metal fasteners. With a nominal diameter of M10 and a length of 39mm, it provides secure fastening in a wide range of applications. The head width of 19mm ensures compatibility with standard M10 tooling. Polycarbonate's inherent non-conductive properties make it ideal for electrical assemblies, marine environments, and areas where galvanic corrosion is a concern. Its lightweight nature contributes to reduced overall assembly weight without compromising structural integrity.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, which can lead to thread stripping or cracking of the screw head.Utilize a torque wrench and adhere to the manufacturer's recommended torque values for polycarbonate fasteners, generally lower than for metal screws.
Using the screw in applications exceeding its temperature or load-bearing limitations.Consult the material datasheets for polycarbonate to confirm its suitability for the operating temperature range and the anticipated mechanical loads of the application.

Common Applications

  • Electrical Enclosures and Assemblies
  • Marine and Coastal Environments
  • Food Processing Equipment
  • Corrosive Chemical Handling Systems
  • Lightweight Structural Components

⚠️ Engineering Warnings

  • Polycarbonate screws have a lower tensile strength and thermal resistance than most metal screws. Do not exceed specified torque limits or operating temperatures.
  • While resistant to many chemicals, compatibility with specific aggressive solvents should be verified before use.
