Steel DIN 6923 Nuts

These bolts are made of carbon steel, often with heat treatments to enhance strength and durability.

Stainless Steel DIN 6923 Nuts

Made from stainless steel (commonly grades A2 or A4), it is known for its excellent corrosion resistance.

Nickel Alloy DIN 6923 Nuts

These bolts are made from nickel alloys like Inconel, Monel, or Hastelloy, which offer exceptional resistance to corrosion, heat, and oxidation.

Features of DIN 6923 Nuts

Flange Design: DIN 6923 nuts have an integrated flange that evenly distributes the load and protects the contact surface, functioning similarly to a washer.
Hexagon Shape: The nut features a hexagonal design, making it easy to tighten or loosen using standard tools.
Material Selection: Typically made from carbon steel, stainless steel, or alloy steel to meet various application requirements.
Strength Grades: Available in multiple strength grades to match the corresponding bolts, ensuring reliable connections.
Anti-loosening Design: Some models have anti-loosening features to enhance vibration resistance and are suitable for dynamic load environments.

Application of DIN 6923 Nuts

Automotive Industry: Chassis, suspension systems, and engine components are widely used to provide high-strength connections.
Machinery Equipment: Used in the assembly of industrial machinery, especially in heavy equipment or machining centers where vibration is a factor.
Construction Industry: Used in steel structure connections or concrete embedded parts, providing additional stability and anti-loosening features.
Electrical Equipment: Ensures high strength and durability when securing motor housings or cabinets.

Advantages & Disadvantages of DIN 6923 Nuts

Advantages:

Easy Installation: The flange design reduces the need for separate washers, simplifying the installation process.
High Load Capacity: The flange provides a larger contact area, effectively distributing pressure and preventing damage to the contact surface.
Good Anti-loosening Performance: The design at the bottom of the flange effectively prevents the nut from loosening due to vibration.
Space-saving: The flange design eliminates the need for separate washers, reducing the assembly’s overall height.
Corrosion Resistance: Surface treatments (such as galvanization) can enhance corrosion resistance, making it suitable for harsh environments.

Disadvantages:

Slightly Higher Cost: Due to the flange design, the material and manufacturing costs of DIN 6923 nuts may be higher than those of standard hex nuts.
Limited Application Range: The flange size may restrict its use in certain precision fastening or space-constrained environments.
Flange May Scratch Surfaces: The bottom of the flange may scratch the surface being fastened during installation, particularly on finely finished materials.
