S-92235A288 M8 x 30 mm Flanged Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with Class 12.9 rating and 170,000 psi tensile strength, ideal for high-stress industrial applications.
• Superior corrosion resistance due to black-oxide coating on alloy steel, extending service life in harsh environments.
• Enhanced load distribution from the integrated flange, reducing surface pressure and preventing loosening under vibration.
• Precise and secure installation with a 6 mm hex socket drive, allowing high torque application without slippage.
• Reliable thread engagement with M8 coarse pitch (1.25 mm) and Class 6g fit, ensuring easy assembly and strong holding power.
• Full threading for maximum grip along the entire 30 mm length, providing consistent clamping force in various material thicknesses.
• Compliance with environmental standards including RoHS 3 and REACH, making them safe for regulated industries.

Professional Applications & Engineering Value

These M8 socket head cap screws are engineered to address critical challenges in heavy-duty machinery, automotive assemblies, and precision equipment. The black-oxide alloy steel construction offers excellent wear resistance and minimizes galling, while the Class 12.9 strength ensures reliable performance under extreme loads and vibrations. The flanged design eliminates the need for separate washers, simplifying installation and reducing part count in industrial fastening systems. With a coarse thread pitch and fully threaded shank, they provide quick assembly and robust retention in metals and composites, making them ideal for applications demanding high tensile strength and long-term reliability.
