S-92235A420 M12 x 40 mm Flanged Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Class 12.9 rating and 170,000 psi tensile strength, ideal for high-stress applications.
• Superior corrosion resistance due to the black-oxide finish on alloy steel, extending service life in harsh environments.
• Secure and efficient installation with a 10mm hex drive and standard socket head profile, preventing stripping and ensuring precise torque application.
• Enhanced load distribution and vibration resistance from the integrated 24mm flange, reducing the risk of loosening under dynamic loads.
• Precise and reliable thread engagement with M12 coarse pitch (1.75mm) and Class 6g thread fit, facilitating quick assembly and strong holding power.
• Full-threaded design for maximum grip across the entire 40mm length, providing consistent clamping force in various material thicknesses.
• Compliance with environmental and safety standards including RoHS 3 and REACH, ensuring safe use in regulated industrial sectors.

Professional Applications & Engineering Value

This M12 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, automotive assembly, and structural frameworks. The black-oxide alloy steel construction offers enhanced corrosion resistance, crucial for operations in humid or chemically aggressive settings, while the Class 12.9 strength rating and Rockwell C39 hardness ensure it withstands extreme tensile and shear forces without failure. The coarse thread pitch and Class 6g thread fit enable rapid installation and reliable performance in high-vibration environments, minimizing maintenance downtime. The integrated flange distributes clamping pressure evenly, preventing surface damage and improving joint integrity. Ideal for applications requiring high tensile strength and durability, such as industrial equipment and precision engineering projects, this screw delivers consistent performance under demanding conditions.
