Metric Size Acorn Nut Clear Zinc Cr3 Plating
Metric Hex Domed Acorn Nuts DIN 1587 Class 6 Overview
Metric hex domed acorn nuts DIN 1587 Class 6 with Zinc Cr3 plating are precision-engineered fasteners designed for reliable performance in industrial, automotive, construction, and electronic applications. These metric acorn nuts feature a domed top that fully encloses exposed bolt threads, improving safety, protecting threads from damage, and delivering a clean, professional finish. When paired with metric bolts, they provide secure fastening and long-term durability in demanding environments.
Key Features of DIN 1587 Metric Acorn Nuts
DIN 1587 Dimensional Standard
Manufactured in accordance with the DIN 1587 standard, these metric hex domed acorn nuts meet strict dimensional and performance requirements. The standard ensures consistent hex sizing, dome height, and thread engagement, allowing the nut to securely cap the bolt while enhancing appearance and protecting threads from dirt, moisture, and mechanical damage.
Class 6 Thread Tolerance
The Class 6 designation indicates precise metric thread tolerances, ensuring a smooth, accurate fit on compatible bolts. This precision reduces the risk of cross-threading, thread stripping, and loosening caused by vibration, making these acorn nuts well suited for assemblies requiring dependable, long-term fastening.
Zinc Cr3 Plating
Zinc Cr3 (trivalent chromium) plating provides excellent corrosion resistance while offering a uniform, smooth surface finish. This environmentally friendly coating protects the fastener against rust, oxidation, moisture, and mild chemical exposure, extending service life in both indoor and outdoor applications.
Benefits of Zinc Cr3 Plated Acorn Nuts
Corrosion Resistance and Sustainability
Zinc Cr3 plating offers reliable corrosion protection without the environmental and health concerns associated with hexavalent chromium finishes. It is safer to handle and compliant with modern environmental standards, making it a preferred choice for manufacturers.
Durable and Clean Appearance
The plated finish enhances durability while maintaining a clean, visually appealing look for exposed fastener installations.
Common Applications
Metric hex domed acorn nuts DIN 1587 Class 6 with Zinc Cr3 plating are widely used in automotive assemblies, construction hardware, industrial machinery, electrical enclosures, and general equipment manufacturing. Their combination of precise fit, corrosion resistance, and protective design makes them a dependable fastening solution for demanding metric applications.
