S-96144A302 M12 x 50 mm DIN 912, ISO 21269 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with Class 12.9 rating and 170,000 psi tensile strength, ensuring reliable performance in high-stress applications.
• Superior corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precise and secure fastening with fine M12 x 1.5mm threads and Class 5g6g fit, minimizing loosening under vibration.
• Easy installation and high torque capability via the 10mm hex drive and standard socket head, allowing for efficient assembly with common tools.
• Versatile partial threading (36mm min thread length on 50mm screw) provides flexibility for varied clamping needs and reduces weight.
• High hardness of Rockwell C37 ensures wear resistance and maintains thread integrity during repeated use.
• Compliance with international standards including DIN 912/ISO 21269, RoHS 3, and REACH, guaranteeing safety and regulatory adherence for global supply chains.

Professional Applications & Engineering Value

These M12 socket head cap screws are engineered to address critical challenges in demanding sectors such as machinery, automotive, and heavy equipment. The black-oxide alloy steel construction combats rust and wear, while the fine thread (1.5mm pitch) and Class 12.9 strength provide superior clamp load retention, preventing joint failure under dynamic loads. The partially threaded design allows for precise engagement in tapped holes or with nuts, reducing stress concentration. Ideal for applications requiring high tensile strength and vibration resistance, these screws ensure long-term reliability in assembly lines, structural frameworks, and precision instruments, minimizing downtime and maintenance costs.
