Product Description

Hexagonal flange screws M12x30 are robust fastening components designed for secure mechanical connections in heavy-duty industrial applications. These M12 hex flange screws feature a hexagonal head with an integrated flange, eliminating the need for separate washers. With a 12 mm nominal diameter and 30 mm length, they provide reliable clamping force for machinery, automotive assemblies, and structural frameworks. Manufactured from high-grade steel, these hex flange bolts operate effectively in temperatures ranging from -40°C to 120°C and withstand vibration-intensive environments. The flanged design distributes load evenly across surfaces, enhancing joint integrity while reducing surface damage. Typical applications include conveyor systems, hydraulic equipment, and renewable energy installations. Key advantages include corrosion-resistant coatings, simplified installation, and compatibility with standard M12 wrench sizes, though alignment precision is critical during assembly.
