S-95003A201 M5 DIN 6923, ISO 4161 Flange Nuts

Key Features & Benefits at a Glance

• Enhanced Load Distribution: The 11.8 mm flange diameter spreads clamping force over a wider area, reducing surface pressure and preventing damage to assembled components.
• Superior Corrosion Resistance: Zinc-plated steel construction provides a durable protective barrier, ensuring long-term reliability in harsh or humid industrial environments.
• High-Strength Performance: Class 10 strength rating guarantees exceptional load-bearing capacity and vibration resistance for demanding, heavy-duty applications.
• Secure and Reliable Fastening: The Class 6H thread fit and M5x0.8mm coarse thread ensure easy, precise assembly and a tight, secure connection that resists loosening.
• Streamlined Assembly Process: The integrated flange design eliminates the need for a separate washer, saving time and reducing the total number of parts in your inventory.
• Global Standard Compliance: Manufactured to DIN 6923 and ISO 4161 standards, ensuring interchangeability, consistent quality, and compatibility with international projects.
• Safe for Regulated Industries: RoHS 3 compliance confirms the nut is free from hazardous substances, making it suitable for use in environmentally conscious and regulated markets.

Professional Applications & Engineering Value

This heavy-duty flange nut is engineered to solve common industrial fastening challenges, such as joint failure under dynamic loads and corrosion-induced degradation. The zinc-plated steel material offers an optimal balance of strength and environmental protection, significantly extending service life in automotive chassis, machinery frames, and electrical enclosures. The integrated flange acts as a built-in washer, providing a larger bearing surface that prevents pull-through and distributes stress effectively, which is critical for maintaining structural integrity in vibrating equipment. Its metric coarse thread (M5x0.8mm) and external hex drive allow for rapid installation with standard tools, reducing assembly time and labor costs while ensuring a secure, Class 6H fit that minimizes the risk of cross-threading and loosening.
