Product Details

Our Plated DIN 1587 Cap Nuts are manufactured to deliver a perfect combination of performance, aesthetics, and value.

  • Versatile Plated Finishes for Every Need: We offer several plating options over a strong carbon steel core to meet different requirements:
    • Nickel Plated: Provides a bright, decorative, almost chrome-like appearance. This finish offers good wear resistance and moderate corrosion protection, making it ideal for visible applications on furniture, fixtures, and automotive trim.
    • White/Blue Zinc Plated (Clear Zinc): This is a standard and highly cost-effective finish that provides good corrosion resistance for indoor or mild environments. The clean, silver-blue appearance is suitable for a wide range of general-purpose applications.
    • Other Finishes: We can also provide other finishes like Black Oxide for a dark, non-reflective look, or Yellow Zinc for enhanced corrosion resistance, available upon request.
  • Strong Carbon Steel Core: The base of the nut is forged from high-quality carbon steel, available in various property classes (e.g., 4.8, 8.8). This allows you to choose the appropriate strength for your application, from decorative use to light-load-bearing connections.
  • DIN 1587 Standard for a Professional Finish: Manufactured in strict compliance with the DIN 1587 standard, these nuts guarantee uniform hexagonal dimensions, dome height, and thread profiles. This ensures a consistent, secure, and professional fit for every application.
