automotive fasteners

Fasteners and fixtures that connect structural components must adhere to increasingly stringent durability standards. Our innovative corrosion protection systems, which include zinc, zinc nickel, zinc iron electrolytes, passivates, lubricated sealers, and zinc flake coatings, provide exceptional protection against corrosion while maintaining defined friction coefficients and ensuring color stability on various materials. These systems have received widespread approval from leading global automotive manufacturers for both conventional internal combustion engine (ICE) and electric powertrain applications.

Zinc and zinc alloys serve as cost-effective, high-performance coatings that preserve dimensional tolerances while offering superior resistance to corrosion, especially for steel fasteners. Our fastener finishing solutions cater to diverse applications, from high-heat engine components to EV-specific fasteners that require enhanced cleanliness and reliable fastening on fine-pitched threads. Exterior coated fasteners, often used in chassis areas and high-visibility body trim, face prolonged exposure to harsh elements and de-icing chemicals, making robust corrosion resistance vital for aesthetic appeal and compliance. Similarly, interior fasteners benefit from coatings that marry corrosion protection with decorative finishes, particularly in components like dashboard screws. Safety-critical coated fasteners across systems such as wheels, safety restraints, steering, suspension, and brakes play a crucial role in minimizing risk and ensuring consistent performance in automotive applications.
