Détails du produit

Our Dacromet DIN 934 Hex Nuts are engineered for excellence, providing a unique combination of strength, durability, and advanced protection.

• Advanced Dacromet Coating: This is a water-based, inorganic coating composed of zinc and aluminum flakes in a chromate binder. Applied via a dip-spin process and then cured, it forms a multi-layered, sacrificial barrier. This provides exceptional corrosion resistance, often exceeding 500-1000 hours in salt spray tests, without the risk of hydrogen embrittlement.
• No Hydrogen Embrittlement: Unlike electroplating processes, the Dacromet application process is free from acid and electrolysis, which eliminates the risk of hydrogen embrittlement. This makes it the ideal coating for high-strength fasteners (Class 8.8 and above), ensuring they maintain their full mechanical integrity without the danger of brittle failure under load.
• DIN 934 Norme de compatibilité universelle : These nuts are manufactured in strict accordance with the DIN 934 standard, ensuring consistent dimensions and thread tolerances. This guarantees a perfect fit with any standard metric bolt or stud, simplifying assembly and ensuring reliable clamping force.
• Thin-Film Application for Precision Fit: The Dacromet coating is a thin, non-electrolytic film. This means that, unlike thick coatings like hot-dip galvanizing, it does not require the nut threads to be overtapped. This preserves the original thread geometry for a precise, secure fit.
