• Exceptional load-bearing capacity from Class 10.9 strength grade, supporting up to 150,000 PSI tensile stress for demanding applications.
• Enhanced stability and vibration resistance due to the integrated flange design, eliminating the need for a separate washer.
• Reliable fastening performance with fully threaded M12 coarse pitch (1.75mm), ensuring quick installation and secure grip in various materials.
• Precise torque application enabled by the external hex drive and standard 16mm head width, reducing slippage during assembly.
• Consistent dimensional accuracy with Class 6g thread fit, providing reliable interchangeability and reducing assembly errors.
• Long-term durability backed by Rockwell C32 hardness, maintaining structural integrity under repetitive stress.

Professional Applications & Engineering Value

This M12 hex flange screw is engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, automotive frameworks, and structural steel connections. The black-phosphate steel material offers a protective layer that significantly reduces oxidation and wear, ideal for environments exposed to moisture or chemicals. With its fully threaded coarse pitch design, it ensures rapid installation and superior holding power in soft or brittle substrates, minimizing the risk of stripping. The integrated flange distributes clamping force evenly, preventing surface damage and enhancing joint stability under dynamic loads. Compliant with ISO 898-1 and DIN 6921 standards, it delivers consistent performance for engineers prioritizing reliability, efficiency, and compliance in high-tensile strength applications.
