Product Description

Our stainless steel flange nuts, manufactured to GB6177 and compatible with DIN6923, ISO4161 standards, are premium fasteners integrating a hex nut with an integrated flange. Available in 201, 304 (A2-70), 316 (A4-80) stainless steel grades, they deliver exceptional corrosion resistance, high tensile strength, and reliable anti-loosening performance, ideal for harsh environments.
Key Features & Benefits
Superior Material Quality: Made of high-grade stainless steel, 201 for cost-effective general use, 304 for standard corrosion resistance, 316 for superior anti-rust in marine/chemical settings. All pass strict quality inspections for durability and stability.
Integrated Flange Design: The built-in flange acts as a washer, distributing clamping force evenly to reduce surface damage and eliminate the need for separate washers, simplifying installation.
Anti-Vibration Serrations: Optional serrated flange surface enhances friction, preventing loosening under vibration, perfect for automotive, machinery, and heavy-duty equipment.
Precision Threads: Coarse/fine threads (M5-M30) are precision-tapped for smooth mating with bolts, ensuring tight and secure connections.
Multiple Finishes: Plain, passivated, or polished finishes enhance corrosion resistance and aesthetics, meeting diverse application needs.
