Product Description

These Hex flange screws DIN 6921 feature M5x45 dimensions with metric hex head flange design, manufactured to ISO 7380 standards. Constructed from steel grade 8.8 with zinc-plated finish, they integrate a built-in flange washer for vibration resistance and reduced component count. Suitable for voltages under 1000V AC/DC in -50°C to +120°C environments, these M5x45 hex flange screws deliver 8-10 Nm torque capacity. Widely used in machinery, automotive assemblies, and structural frameworks for their secure clamping force and space-efficient installation. Advantages include simplified assembly and corrosion resistance, though prolonged exposure to harsh chemicals may compromise coating integrity. The 13mm flange diameter ensures even load distribution across joined surfaces.
