Materials and Manufacturing Process

The SS Black Oxide Hexagon Bolt is manufactured using premium grades of stainless steel, typically A2-70 for general use and A4-80 for marine or acidic environments.

The manufacturing process includes:

  1. Cold forming or hot forging of stainless steel rods.
  2. Precision thread rolling to ensure consistent and tight thread tolerances.
  3. Hex head shaping through mechanical pressing.
  4. Black oxide coating, which serves as a mild corrosion inhibitor and enhances appearance.
  5. Final inspection for conformity to DIN933 standards.

This sequence ensures the bolt meets rigorous demands for mechanical strength and cosmetic appeal, making it ideal for high-visibility applications.

Typical Applications and Industries

  • Automotive engineering
  • Marine hardware and boat fittings
  • Construction and structural components
  • Renewable energy installations such as solar panel frames and wind turbines
  • Machinery and equipment assembly
  • Industrial enclosures and frames

These applications demand fasteners that are resistant to corrosion, provide long service life, and maintain structural integrity under stress — qualities that the DIN933 hexagon bolt consistently delivers.

Advantages and Competitive Strengths

Premium Material Selection

The use of high-grade stainless steel ensures excellent corrosion resistance, even in challenging environments such as coastal or chemical industries.

Precision Engineering

Each bolt is subjected to strict thread rolling and tolerance control, ensuring exceptional fit and load-bearing capacity in all types of mechanical assemblies.
