Description
Stainless Steel Hex Flange Nuts manufactured to the DIN 6923 standard are high-performance fasteners designed for secure and reliable connections in demanding environments. These hexagon flange nuts feature an integrated, serrated flange that functions as a built-in washer, eliminating the need for additional components while enhancing load distribution and locking performance.
Available in 304, 316, 316L, or 310S stainless steel, these flange nuts offer excellent corrosion resistance, mechanical strength, and long-term durability. The toothed flange provides a non-slip locking action, making these fasteners particularly suitable for applications exposed to vibration, dynamic loads, or harsh environmental conditions. Stainless Steel Hex Flange Nuts are widely used across construction, manufacturing, mechanical engineering, and industrial equipment assemblies.
Features & Benefits
- Exceptional Corrosion Resistance: Made from multiple grades of stainless steel, these nuts offer superior resistance to wear, rust, and oxidation, ensuring long-term durability in even the most humid or chemical-rich environments.
- Secure, Non-Slip Locking: The toothed flange on the underside of the nut grips the mating surface, creating a firm and secure lock that prevents the fastener from loosening under vibration.
- Improved Load Distribution: The integrated flange provides a wider bearing surface, which helps to distribute the pressure more evenly across the clamped material. This reduces the risk of damage and ensures a stronger, more stable connection.
- Standardized Quality: Conforming to the DIN6923 standard, these nuts meet stringent dimensional and quality specifications, making them a dependable choice for a wide range of engineering applications.

FAQ:
Q1: Why should I use a flange nut instead of a nut and a separate washer?
A: The all-in-one design of the Stainless Steel Hex Flange Nut simplifies assembly and ensures that the locking surface is always perfectly aligned with the nut. This reduces the risk of component loss and improves load distribution compared to using separate parts.
Q2: What is the benefit of the 310S stainless steel grade?
A: While 304 and 316 are excellent for corrosion resistance, 310S is specifically utilized for its high-temperature oxidation resistance, making it suitable for specialized manufacturing and mechanical environments.
Q3: Does the toothed flange damage the mating surface?
A: The "teeth" are designed to grip the surface to prevent loosening under vibration. While they provide an excellent mechanical lock, they are best used on hard surfaces or in applications where the security of the connection is more critical than minor surface marking.
Q4: Are these nuts compatible with standard bolts?
A: Yes, as long as the thread pitch and size match, these DIN 6923 nuts will fit standard bolts. However, they are most effective when paired with high-quality stainless steel bolts to maintain consistent corrosion resistance across the entire assembly.
