• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh industrial environments, minimizing maintenance needs.
• Precise flush mounting with a standard 90° countersink angle and flat head design provides a smooth surface finish, enhancing safety and aesthetics.
• Efficient installation and removal using the 6mm hex drive allows for high torque application, speeding up assembly processes.
• Consistent thread engagement with coarse M10x1.5mm threads and Class 6g fit offers secure fastening in various materials, improving joint integrity.
• Full threading along the 12mm length maximizes grip and load distribution, ideal for applications requiring uniform clamping force.
• Compliance with international standards including DIN 7991/ISO 10642 ensures interoperability and quality, supporting global supply chain requirements.

Professional Applications & Engineering Value

This M10 flat head screw is engineered from black-oxide alloy steel to address common industrial challenges such as vibration loosening and environmental degradation. The Class 10.9 strength grade and Rockwell C32 hardness provide robust resistance to dynamic loads, making it suitable for heavy-duty machinery, automotive assemblies, and structural frameworks. The coarse thread design with a 1.5mm pitch ensures quick installation and reliable holding power in soft or brittle materials, while the fully threaded configuration enhances versatility across varying material thicknesses. By integrating a 90° countersink angle and hex drive, it enables seamless flush mounting in pre-drilled holes, reducing protrusion risks in confined spaces. Ideal for industrial applications demanding high corrosion resistance and durability, this screw minimizes downtime and maintenance costs in demanding operational environments.
