Product Description

The M8-40 Hex Flange Screw, compliant with DIN 6921 Flange Bolt specifications, features an M8x40 thread size with a hexagonal head and integrated flange for secure fastening in industrial applications. Designed for durability, this carbon steel bolt has a flange diameter of 24 mm and a thickness of 2.6 mm, supporting torque values up to 28 Nm. It operates reliably within a temperature range of -50°C to +120°C, ideal for machinery, automotive assemblies, and structural frameworks. The zinc-plated M8x40 Hex Flange Bolt offers corrosion resistance and vibration-resistant clamping force, reducing the need for separate washers. While its high-strength design ensures stability under load, installation requires compatible hexagon socket tools (8 mm key). The flanged profile enhances load distribution but may limit use in tight-clearance environments. Widely adopted in manufacturing and construction industries due to its standardized DIN 6921 compliance and versatile fastening performance.
