DIN 6923 Grade 12.9 Flange Nuts | Hot Dip Galvanized High Strength Nuts

The DIN 6923 flange nut combines a standard hex nut body with a built‑in circular flange. The flange increases the contact area between the nut and the workpiece, helping distribute fastening force more evenly and reduce surface pressure. This design makes it practical for assemblies where stable tightening, fast installation, and strong clamping performance are important.

The product is supplied as a high strength Grade 12.9 flange nut. The Grade 12.9 classification is suitable for high‑strength fastening applications and is commonly used where stronger mechanical performance is required than ordinary low‑grade nuts.

The surface treatment is hot dip galvanizing. Hot dip galvanized coating provides a thicker zinc layer than ordinary electro‑zinc plating, helping improve corrosion resistance in outdoor, construction, structural, and industrial environments.

Specification Table

Material and Grade Explanation

Material: High‑Strength Steel

This flange nut is supplied as a high‑strength steel fastening component for demanding bolt connections. The material selection supports the Grade 12.9 strength requirement and is suitable for industrial and structural fastening applications.

Grade: 12.9

Grade 12.9 indicates a high‑strength fastening grade. It is suitable for applications requiring stronger mechanical performance than ordinary lower‑grade nuts. For matching assemblies, bolts, threaded rods, and washers should be selected according to the required project standard and mechanical load.

Surface Finish: Hot Dip Galvanized

Hot dip galvanizing provides a thick zinc coating for improved corrosion protection. It is commonly used for outdoor construction, steel structures, machinery, and environments where the fastener may be exposed to moisture or weathering.

Applications

DIN 6923 Grade 12.9 hot dip galvanized flange nuts are suitable for:

• Steel structure fastening
• Construction engineering
• Machinery assembly
• Heavy‑duty equipment installation
• Infrastructure projects
• Bracket and support systems
• Bolt and threaded rod assemblies
• Industrial maintenance
• Outdoor fastening applications
• Mechanical connection systems requiring higher strength

Why Choose DIN 6923 Flange Nuts

A DIN 6923 flange nut offers better load distribution than a standard hex nut because the built‑in flange increases the bearing surface. This helps improve assembly stability and can simplify installation where a separate washer is not required.

The Grade 12.9 high strength classification makes this flange nut suitable for stronger fastening requirements, while the hot dip galvanized finish helps improve long‑term surface protection. For bulk procurement, the product is practical for contractors, fastener distributors, machinery manufacturers, and engineering buyers.
