Applications & Advantages of DIN 931 Dacromet Hex Bolt
Core Applications
Suitable for automotive manufacturing (engine compartments, chassis components) and marine equipment (hulls, offshore structures) where corrosion resistance is critical.
Widely used in industrial machinery, electrical cabinets, and outdoor infrastructure (bridges, solar brackets) exposed to humidity, salt spray, or temperature fluctuations.
Ideal for assembly requiring partial thread engagement (per DIN 931 standard) in heavy-duty fixed connections.
Key Advantages
Superior corrosion protection: Dacromet coating delivers 500+ hours of salt spray resistance, outperforming traditional galvanizing.
Mechanical reliability: Complies with DIN 931 specifications, featuring high tensile strength (8.8/10.9 grades) and precise thread fit for stable load-bearing.
Environmental safety: Non-toxic, chromium-free coating avoids hydrogen embrittlement, safe for high-strength bolt applications.
Longevity in harsh conditions: Resists moisture, chemicals, and UV radiation, reducing maintenance and replacement costs.
