Key Features & Benefits at a Glance
- Enhanced load distribution with 37mm flange diameter prevents surface damage and reduces point loading
- Superior corrosion resistance from 18-8 stainless steel construction ensures longevity in harsh environments
- Reliable thread engagement with Class 6H thread fit provides consistent clamping force and vibration resistance
- Quick installation through standard 30mm external hex design compatible with common wrench tools
- Industrial compliance meeting DIN 6331 specifications guarantees dimensional accuracy and interchangeability
- Environmental safety with RoHS 3 and REACH compliance for responsible manufacturing standards
- Optimal material strength from 6mm flange thickness withstands high-torque applications without deformation
Professional Applications & Engineering Value
These M20 flange nuts with 2.5mm coarse thread pitch deliver critical engineering solutions for heavy machinery, structural assemblies, and automotive applications. The integrated 37mm flange eliminates need for separate washers while distributing clamp load across wider surface areas, preventing joint loosening from vibration - a common industrial challenge. Manufactured from 18-8 stainless steel, these metric flange nuts maintain integrity in corrosive environments where carbon steel components would fail. The external hex drive and 30mm width provide secure tool engagement for high-torque installation, while the Class 6H thread fit ensures precise mating with corresponding bolts for reliable performance in dynamic loading conditions.
Specification Summary & Compliance
This DIN 6331 flange nut features M20 x 2.5mm coarse thread with Class 6H thread fit tolerance, 30mm hex width, and 37mm flange diameter with 6mm thickness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring hazardous substance restriction compliance. The metric system components maintain international specification compatibility for global industrial applications.
