Detailed Engineering Specifications

Designed for demanding industrial environments, this M16x86mm hex head cap screw is precisely manufactured from high-grade brass. The material's inherent resistance to corrosion, especially in saline or chemically aggressive atmospheres, makes it suitable for marine, chemical processing, and electrical applications where ferrous fasteners would degrade. The substantial 20mm head width provides ample surface area for torque application, ensuring secure fastening. The M16 thread size conforms to international standards for compatibility with a wide range of industrial equipment and components. Its non-sparking characteristics are critical for hazardous environments where ignition sources must be eliminated.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the screw, potentially stripping threads or deforming the mating material.Utilize a torque wrench set to the manufacturer's recommended specification for the application and materials.
Using the wrong size wrench, leading to damage of the hex head or an insecure fit.Always use a wrench or socket that precisely matches the 20mm head width of the cap screw.

Common Applications

  • Marine hardware and fittings
  • Chemical processing equipment
  • Electrical enclosures and grounding
  • Instrumentation panels

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid excessive force that could damage threads.
  • While corrosion-resistant, brass can still be affected by certain strong acids or alkalis. Verify compatibility for your specific environment.
