Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments due to 316 stainless steel construction
- Eliminates the need for a separate washer with its integrated 37mm flange for faster assembly and increased bearing surface
- Reliable, high-strength fastening ensured by the Class 6H thread fit and compliance with the DIN 6331 standard
- Excellent resistance to chemical and atmospheric corrosion, making it ideal for marine, chemical, and food processing applications
- Robust and durable performance in heavy-duty applications thanks to the 6mm flange thickness and coarse (M20x2.5) thread profile
- Safer for sensitive applications as it is certified REACH and RoHS 3 compliant, free from hazardous substances
- Easy installation and removal with a standard 30mm external hex drive for common tooling
Professional Applications & Engineering Value
This M20 x 2.5mm 316 Stainless Steel Flange Nut is engineered to solve critical challenges in demanding industrial applications. Its 316 stainless steel material provides exceptional corrosion resistance, crucial for infrastructure exposed to moisture, chemicals, and salt spray, thereby preventing fastener failure and reducing maintenance costs. The integrated 37mm flange distributes clamping force over a wider area, preventing surface damage and loosening under vibration, which is a common issue in machinery and heavy equipment. The coarse metric thread and external hex drive ensure quick, secure assembly, making it a reliable, time-saving component for construction, marine, and processing plant assemblies where durability and compliance with DIN 6331 are paramount.
Specification Summary & Compliance
This flange nut features an M20 metric coarse thread with a 2.5mm pitch and a Class 6H thread fit, ensuring high precision and interchangeability. It is manufactured in strict accordance with the DIN 6331 standard. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, confirming its adherence to environmental and safety regulations for use in various global markets.
