S-93700A210 M6 x 12 mm 12-Point Screws

Key Features & Benefits at a Glance

• Exceptional Durability – Black-oxide alloy steel construction provides superior corrosion resistance, extending service life in harsh industrial environments.
• High Tensile Strength – Rated at 180,000 psi tensile strength for reliable performance in heavy-duty and high-stress applications.
• Precision Thread Fit – Class 4h thread fit ensures tight, secure fastening with minimal risk of loosening under vibration or load.
• Optimized Drive Engagement – 8 mm external 12-point drive offers excellent torque transmission and reduces the risk of tool slippage during installation.
• Enhanced Load Distribution – Integrated flange design eliminates the need for a separate washer, providing a larger bearing surface and improved clamping force.
• Full Thread Engagement – Fully threaded M6 x 1mm coarse pitch design allows for maximum grip and holding power across the entire fastener length.
• Robust Material Hardness – Rockwell C38 hardness ensures high resistance to wear and deformation, maintaining fastener integrity over time.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M6 12-point flange screws address critical challenges in assembly and maintenance. The black-oxide alloy steel material not only resists corrosion but also withstands high mechanical stresses, making these screws ideal for automotive, machinery, and structural applications where vibration resistance and long-term reliability are paramount. The fully threaded coarse pitch metric design ensures quick installation and superior retention in materials like steel and cast iron, while the flanged head simplifies assembly by integrating a washer-like function, reducing part count and installation time. This combination of high tensile strength and precise Class 4h thread fit delivers consistent performance in rigorous environments, minimizing downtime and maintenance costs.
