Specification

SEODescription

The Hex flange screw M6x25, also known as the M6x25 hexagonal flange bolt or DIN6921 M6x25 flange screw, is a standardized fastener featuring a hexagonal head with an integrated flange for even load distribution. Designed per DIN6921 specifications, it has a 6mm thread diameter and 25mm shank length, typically used in mechanical engineering, automotive assembly, and industrial equipment. The flange eliminates separate washers, providing enhanced clamping force and vibration resistance. Compatible with standard M6 nuts, it operates in temperatures from -50°C to +300°C (material-dependent) and suits environments requiring robust structural connections. Advantages include space efficiency and reduced loosening risk, though installation may require specific clearance for the flange. Widely applied in machinery requiring secure modular component attachments, its zinc-plated or stainless steel variants ensure corrosion resistance.
