Manufacturer: DONGGUAN DAYA PRECISION HARDWARE CO., LTD.
As a professional and experienced fastener manufacturer based in China, DONGGUAN DAYA PRECEMA HARDWARE CO., LTD. offers a specialized line of high-performance Carbon Steel Screws treated with the world-class Dacromet or Geomet zinc flake coating system. These fasteners are engineered for applications demanding exceptional corrosion resistance and high structural integrity.
Exceptional Corrosion Resistance: The Dacromet/Geomet system utilizes an advanced zinc and aluminum flake matrix, providing superior barrier and sacrificial protection.
High Salt Spray Rating: Easily passes 1000+ hours in the Neutral Salt Spray Test (NSS) (ASTM B117 / ISO 9227), significantly outperforming traditional electro-plating.
Hydrogen Embrittlement-Free: The non-electrolytic application process eliminates the risk of hydrogen embrittlement, making these screws the ideal choice for high-strength steel fasteners used in critical assemblies (e.g., automotive, wind power).
Environmentally Compliant (Geomet): Geomet coatings are water-based and Chrome-free ($\text{Cr}^{6+}$), fully compliant with major international environmental regulations, including RoHS, REACH, and ELV directives.
Thermal and Chemical Stability: Exhibits excellent resistance to high temperatures (up to approx. $\text{250}^\circ\text{C}$) and various industrial solvents and automotive fluids.
Versatile Customization: Available in a wide range of types, head styles, and thread formations (including self-tapping, machine screws, self-drilling, etc.) to meet specific project specifications.
Direct Manufacturer Advantage: As a direct factory source, we ensure stringent quality control from raw material procurement to final packaging, supported by an advanced quality management system.
Technical Expertise: Our deep experience in producing Dacromet/Geomet fasteners allows us to offer tailored solutions based on your specific operational environment and performance demands.
Efficient Logistics: Strategically located in Dongguan, China, we benefit from a mature supply chain network, guaranteeing fast turnaround and on-time delivery.
Contact us today to request samples, detailed specifications, and a quotation.
