DIN 6923 Serrated Flanged Hexagon Nuts — Bright Zinc Plated Steel (Class 4)

FULLERKREG DIN 6923 serrated hexagon flange nuts in Class 4 are manufactured from low carbon steel Q195, conforming to DIN 6923. The integrated serrated flange bearing surface distributes clamping load over a wider area and provides built-in vibration resistance — eliminating the need for a separate lock washer. Surface finish: bright zinc plated with trivalent chromium passivation (Zn + Cr3), providing reliable corrosion protection for general indoor and light outdoor applications. Thread: metric coarse (ISO 68-1). RoHS compliant.

Dimensional Data — DIN 6923 Serrated Flange Nut (Bright Zinc Plated, Class 4)

All dimensions in mm. Unit weight is approximate (calculated at steel density 7.85 g/cm³); actual weight may vary slightly by batch. Tolerances per DIN 6923. Zinc plating adds approximately 5–25 µm per side; verify fit with mating components before ordering in bulk.

Standard Reference

DIN 6923 specifies hexagon flange nuts with a serrated or plain bearing surface. The serrated variant provides mechanical locking through the teeth on the flange underside, which bite into the mating surface under torque — eliminating the need for a separate spring or toothed washer. Bright zinc plating per ISO 4042 with trivalent chromium (Cr3) passivation ensures RoHS compliance and provides adequate corrosion protection for general engineering applications. FULLERKREG manufactures to the current edition of DIN 6923 with full dimensional traceability.
