S-91290A626 M12 x 50 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Class 12.9 rating and 170,000 psi tensile strength ensuring reliable performance under high stress.
• Superior corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precise and secure fastening with Class 5g6g thread fit and M12 coarse thread (1.75mm pitch) for easy assembly and vibration resistance.
• High durability and wear resistance from Rockwell C37 hardness, maintaining integrity in repetitive or heavy-load scenarios.
• Efficient installation and removal using a 10mm hex drive and standard socket head design, reducing tool slippage and downtime.
• Full thread engagement for versatile use as the screw is fully threaded, providing consistent clamping force along the entire 50mm length.
• Compliance with international standards including DIN 912/ISO 4762, RoHS 3, and REACH, ensuring quality and environmental safety.

Professional Applications & Engineering Value

This M12 socket head cap screw is engineered to address critical challenges in industrial and engineering applications where failure is not an option. The black-oxide alloy steel construction offers enhanced corrosion resistance, making it ideal for environments exposed to moisture, chemicals, or outdoor elements. With a fully threaded design and Class 5g6g thread fit, it ensures precise alignment and robust holding power in machinery, automotive assemblies, and structural frameworks. The 10mm hex drive allows for high-torque installation without stripping, while the coarse thread (1.75mm pitch) facilitates quick assembly in materials like steel or cast iron. By combining high tensile strength (170,000 psi) and Rockwell C37 hardness, this fastener minimizes the risk of shear or fatigue in heavy-duty fastening scenarios, providing long-term reliability and reducing maintenance costs.
