Common Materials of DIN 6923 Flange Nuts

DIN 6923 flange nuts are widely used in machinery, the automotive industry, construction, and furniture assembly. Their integrated flange design distributes the load evenly, preventing surface damage and ensuring a secure fastening. Choosing the right material is crucial to ensure both strength and corrosion resistance.

As a professional flange nut supplier, we are glad to share the most common materials and surface treatments used for DIN 6923 flange nuts.

Carbon Steel DIN 6923 Flange Nuts

Carbon steel is the most widely used material for DIN 6923 flange nuts, offering excellent strength and cost-effectiveness. Depending on the property class, carbon steel flange nuts can handle different levels of mechanical stress:

• Grade 8: Suitable for medium-load machinery and general equipment.
• Grade 10: Provides higher tensile strength, often used in automotive manufacturing and heavy machinery.
• Grade 12: Designed for high-strength connections in steel structures, engines, and industrial applications.

Carbon steel DIN 6923 flange nuts are the ideal choice when strength and affordability are the primary considerations.

Stainless Steel DIN 6923 Flange Nuts (304 & 316)

When corrosion resistance is essential, stainless steel becomes the preferred option:

• 304 Stainless Steel: Offers excellent corrosion resistance and strength, suitable for outdoor and humid conditions.
• 316 Stainless Steel: Contains molybdenum for enhanced resistance against chlorides and chemicals, making it ideal for marine environments, chemical plants, and coastal installations.

Stainless steel DIN 6923 flange nuts ensure long-term durability without frequent maintenance.

Surface Treatments for DIN 6923 Flange Nuts

To further improve corrosion resistance and extend service life, different coatings and finishes are commonly applied:

• Zinc Plating (Electro-galvanized or Hot-dip galvanized): Provides good protection against rust in outdoor and humid environments.
• Nickel Plating: Enhances both corrosion resistance and surface brightness, resulting in a more aesthetically pleasing appearance.
• Phosphating: Offers anti-rust and anti-wear properties, often used in industrial machinery.
• Dacromet Coating: A high-performance anti-corrosion treatment, widely applied in automotive and long-term outdoor applications.

These treatments allow carbon steel DIN 6923 flange nuts to achieve performance levels close to stainless steel at a more economical cost.

Applications of DIN 6923 Flange Nuts

Thanks to their reliability and versatility, DIN 6923 flange nuts are commonly used in:

• Automotive manufacturing (frames, engines, suspension systems)
• Heavy-duty machinery and equipment
• Steel structures and construction projects
• Furniture and wood assembly (eliminating the need for washers)

Selecting the right material and finish ensures that flange nuts deliver optimal performance for specific industries and environments.
