Dacromet Automotive Wheel Nuts Manufacturers

-- Steady & Reliable Manufacturer --

Introduction

Dacromet coated wheel nuts are a premium choice for the automotive industry, offering exceptional corrosion resistance and high performance without the risk of hydrogen embrittlement. The Dacromet coating is a water-based, chromium-free zinc/aluminum flake dispersion that creates a thin, uniform layer, crucial for maintaining precise torque tension specifications in wheel assembly. These nuts are designed for reliability and safety on passenger and commercial vehicles.

Applications

  • Vehicle Wheel Assembly: Securing wheels on cars, trucks, and buses.

  • Brake and Suspension Systems: Used in critical underbody components exposed to road spray and salt.

  • Engine Compartments: Where fasteners are exposed to heat and mild chemical splash.

  • Trailer and RV Manufacturing: Requiring durable, long-lasting external components.

Advantages

  • High Corrosion Performance: Excellent barrier protection, far superior to standard electro-plating.

  • Consistent Torque: The controlled thickness of the coating ensures reliable and accurate torque-tension values during installation.

  • Chromium-Free: Environmentally preferred coating option (especially the Geomet version).

  • Chemical Resistance: Good resistance to automotive fluids like brake fluid and oil.

Payment & Shipping

We primarily serve Tier 1 and Tier 2 automotive suppliers and offer payment terms of TT 45 Days after shipment. Wheel nuts are delivered in high-volume, pre-counted cartons or pallet bins to integrate seamlessly into automated assembly lines. JIT delivery schedules are strictly maintained.

FAQ

  • Q: Why is Dacromet coating safer than traditional plating for wheel nuts?
  • A: Dacromet is an applied coating system and does not involve an acid bath, which is used in electro-plating (like zinc plating). The acid bath introduces the risk of hydrogen absorption, leading to hydrogen embrittlement, which can cause catastrophic brittle failure in high-strength automotive steel components.
  • Q: Is Dacromet the same as Geomet?
  • A: They are very similar zinc flake coating technologies. Dacromet was the original process, while Geomet is a subsequent generation that is often chromium-free, meeting stricter environmental regulations (RoHS, REACH).
