DIN 6923 Hexagon Flange Nuts China Factory Suppliers High Strength Metric Fasteners
LONGZE high-performance DIN 6923 Hexagon Flange Nuts are precision-engineered to optimize industrial fastening by integrating the nut and washer into a single component. This innovative design significantly expands the bearing surface and improves load distribution, eliminating the need for separate washers and streamlining the assembly process in high-stress environments.
As a critical component of the LONGZE GFM-WCR System, these flange nuts are available in both smooth and serrated bearing faces to provide superior resistance against loosening under intense vibration. Specifically designed for automotive chassis, solar racking, and heavy industrial assembly lines, our DIN 6923 nuts ensure maximum structural integrity with certified Class 8 and 10 property levels.

Key Advantages
Vibration Resistance
Serrated faces provide a powerful "biting" force to prevent loosening in high-vibration automotive and industrial applications.
Assembly Efficiency
Integrated flange design eliminates the need for separate washers, reducing part count and labor time during installation.
Superior Load Distribution
The enlarged bearing surface distributes clamping force more evenly, protecting the mating material from deformation.
Multi-Standard Mapping
Seamless dimensional mapping between DIN, ISO, and ASME standards ensures global compatibility for any project.
Corrosion Protection
Advanced surface treatments including Zinc Flake and Hot Dip Zinc per ISO 9227 salt spray testing standards.
Full Traceability
Digital batch tracking from raw material to final container loading ensures complete material chemical verification.

Frequently Asked Questions
Serrated nuts (DIN 6923) are ideal for high-vibration environments where the nut must "bite" into the surface to prevent rotation. Smooth flange nuts are used when surface damage or scratching to the mating part must be avoided.
ISO 4161 is the modern international equivalent of DIN 6923. While they are broadly similar, certain dimensions like width across flats for M10 and M12 may differ. LONGZE provides compliance based on your specific Technical Data Sheet (TDS).
We offer Class 8, 10, and 12 property levels. Class 10 is highly recommended for heavy industrial assembly and automotive chassis to ensure high tensile strength and durability.
We provide multiple coating options including Zinc Plating (ISO 4042), Zinc Flake (ISO 10683), and Hot Dip Zinc (ISO 1461). All coatings undergo rigorous NSS salt spray testing per ISO 9227 standards.
Yes, all LONGZE DIN 6923 shipments come with Full MTC 3.1 Traceability, providing detailed chemical and mechanical verification of the steel used.
For optimal flange-integrated environments, we recommend DIN 6921 (Flange Bolts), ISO 4162, or ASME B18.2.3.4M. They also pair perfectly with standard DIN 933 or ISO 4017 bolts.
