Zinc-Nickel Nuts for Automotive and Industrial Applications

Zinc-nickel nuts are threaded fasteners designed to work with zinc-nickel bolts, providing matched corrosion protection for complete fastener assemblies.

Using matching zinc-nickel coated nuts and bolts ensures consistent corrosion protection across the entire fastener assembly, preventing galvanic corrosion and providing uniform protection in exposed areas.

Product Range

Our zinc-nickel nut range includes:

  • Hex nuts (standard and heavy)
  • Flange nuts
  • Lock nuts (nylon insert, all-metal)
  • Metric thread sizes: M4 – M20
  • Strength grades: 8 / 10 / 12
  • Custom configurations available

Why Zinc-Nickel for Nuts?

Zinc-nickel coating provides:

  • Superior corrosion resistance (720-1000+ hours salt spray)
  • Matched protection with zinc-nickel bolts
  • Protection for exposed threaded areas
  • Heat resistance up to 200°C

  • Engine and transmission assemblies
  • EV battery enclosures and structural components
  • Industrial equipment requiring matched fastener sets

Frequently Asked Questions

What are zinc-nickel nuts?

Zinc-nickel nuts are threaded fasteners (nuts) electroplated with a zinc-nickel alloy coating containing 12-15% nickel. This coating provides superior corrosion resistance compared to conventional zinc-plated nuts, making them ideal for automotive and industrial applications.

What types of nuts are available?

We supply various nut types including hex nuts, flange nuts, lock nuts, and custom configurations. Available in metric thread sizes M4-M20, with strength grades 8, 10, and 12, matching corresponding bolt grades.

Are zinc-nickel nuts suitable for automotive applications?

Yes, zinc-nickel nuts are highly suitable for automotive applications, especially when used with zinc-nickel bolts to create matched fastener sets. They provide consistent corrosion protection and reliable performance in harsh automotive environments.

What is the advantage of matching zinc-nickel nuts with bolts?

Using matching zinc-nickel coated nuts and bolts ensures consistent corrosion protection across the entire fastener assembly. This prevents galvanic corrosion between dissimilar coatings and provides uniform protection in exposed areas.

Can you supply custom zinc-nickel nuts?

Yes. We support custom zinc-nickel nuts manufactured to drawings or specifications, including non-standard dimensions, special thread configurations, and unique coating requirements.
