S-91502A255 M12 x 100 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional durability with Class 12.9 alloy steel construction, providing superior resistance to high-stress conditions and extending service life in demanding environments.
• Enhanced corrosion protection from blue-dyed zinc plating, ensuring reliable performance and reduced maintenance in humid or corrosive industrial settings.
• Precise torque application with a 10 mm hex drive and standard socket head, allowing for secure fastening and easy installation in confined spaces.
• Optimized load distribution due to the M12 coarse thread (1.75 mm pitch) and Class 5g6g thread fit, minimizing the risk of stripping and ensuring stable connections.
• Versatile partial threading over a 36 mm minimum thread length, offering flexibility for applications requiring both threaded and unthreaded sections.
• High tensile strength of 170,000 psi and Rockwell C37 hardness, delivering reliable performance under extreme mechanical loads without failure.
• Compliance with international standards including DIN 912/ISO 4762, RoHS 3, and REACH, ensuring safety, quality, and environmental responsibility.

Professional Applications & Engineering Value

This M12 socket head cap screw is engineered to address critical challenges in heavy-duty industrial applications, such as machinery assembly, automotive systems, and structural frameworks. The Class 12.9 alloy steel and Rockwell C37 hardness provide exceptional resistance to fatigue and deformation, reducing downtime and maintenance costs. The blue-dyed zinc plating enhances corrosion resistance, making it ideal for environments exposed to moisture or chemicals. With a 10 mm hex drive and coarse thread pitch, it ensures quick, secure installation and reliable torque transfer, while the partially threaded design allows for precise clamping in complex assemblies. These features make it a top choice for engineers seeking high tensile strength and long-term reliability in metric screw applications.
