Flange Nut

DIN6923 Zinc Plating Hex Flange Nut

DIN6923 Zinc Plating Hex Flange Nut provide a secure and tight fit, while also preventing the nut from loosening due to vibration. This is especially important in industries where machinery and other heavy equipment are used, as any loosening of fittings can cause dangerous and costly consequences. The flange of DIN6923 Zinc Plating Hex Flange Nut acts as a washer, providing additional support while preventing the nut from embedding itself into the surface of the material being fastened. This greatly reduces the risk of damage to the structure, as well as providing a more aesthetically pleasing finish.

Product Details

Product Introduction
Hexagon flange nuts manufactured to DIN 6923 with a zinc-plated carbon steel base. The integrated flange serves as an inseparable load-distributing washer, while serrations on the bearing face bite into the mating surface to resist vibration-induced loosening. The design eliminates the need for a separate flat washer and reduces assembly part count. Standard diameters M5 through M20 are supplied in metric coarse thread.

Material & Mechanical Properties
Cold-formed from carbon steel and tempered for property classes 8, 10, and 12 under ISO 898-2. Proof load and hardness are certified by lot, with traceability to the heat. When matched with bolts of equivalent or higher property class, the nut carries the full proof stress of the bolt assembly without thread stripping.

Geometry & Thread
Internal ISO metric coarse thread per ISO 724. The external hexagon conforms to standard wrench openings. The serrated flange face penetrates paint and surface films during tightening, creating a positive mechanical lock against rotation. The enlarged flange footprint distributes clamp force and prevents embedment into softer structural materials.

Corrosion Protection
Zinc electroplated with clear passivation, applied per ISO 4042/ASTM B633. The zinc layer provides sacrificial cathodic protection for the underlying steel. This finish is suitable for indoor installations and sheltered outdoor environments. For more aggressive atmospheric conditions, zinc-nickel, zinc flake, and hot-dip galvanized alternatives are specified.

Application Suitability
Heavy machinery, engine sub-assemblies, conveyor systems, structural steelwork, and general industrial equipment where vibration and dynamic loads make nut retention critical. Compatible with hex head bolts, socket head bolts, carriage bolts, and other externally threaded fasteners. The one-piece flanged nut simplifies assembly and ensures consistent preload reliability.
