Specification

SEODescription

The M10x20 hexagonal flange screws, compliant with DIN6921 standards, are robust fasteners designed for high-torque applications. These DIN6921 hex flange screws feature an integrated flange with a hexagonal head, M10x20 thread dimensions, and a washer-like base to distribute load efficiently. Manufactured from grade 8.8 steel with zinc-plated corrosion resistance, they operate reliably in temperatures from -50°C to +120°C. The M10x20 hexagonal flange screws are widely used in automotive assemblies, machinery manufacturing, and structural engineering due to their vibration resistance and elimination of separate washers. Key advantages include enhanced joint stability, simplified installation, and compliance with DIN6921 specifications for consistent flange geometry. Limitations include potential galvanic corrosion in harsh environments and requirement for precise torque tools. Their design ensures direct mechanical coupling without electrical interfaces, making them ideal for heavy-duty industrial applications demanding durability and secure fastening.
