S-90997A270 M10 Flange Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with A286 stainless steel construction for extended service life in harsh environments
• Enhanced torque transmission through the external 12-point drive design, preventing tool slippage during installation
• Reliable vibration resistance with the integrated flange that distributes load evenly and eliminates need for separate washers
• Precise thread engagement with Class 5H fit ensuring consistent performance in critical assemblies
• Optimized for fine-thread applications with 1.25mm pitch providing superior clamping force in thin materials
• Reduced assembly time with the combination flange and nut design that simplifies installation processes
• Exceptional high-temperature performance due to A286 material properties maintaining strength in thermal cycling conditions

Professional Applications & Engineering Value

This M10 flange nut with 1.25mm fine pitch addresses critical engineering challenges in industrial fastening applications where vibration resistance and consistent clamping force are paramount. The A286 stainless steel construction provides exceptional strength retention at elevated temperatures up to 700°F (371°C), making it ideal for aerospace, automotive, and heavy machinery applications. The integrated flange with 17.8mm diameter creates a wider bearing surface that prevents loosening under dynamic loads while protecting assembled surfaces from damage. The external 12-point drive configuration enables higher torque application compared to standard hex designs, ensuring secure fastening in confined spaces where conventional wrenches cannot operate effectively. This combination of fine thread spacing and Class 5H thread fit delivers superior fatigue resistance in high-cycle applications, reducing maintenance requirements and downtime.
