S-90180A653 M12 x 70 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical applications.
• Superior corrosion resistance from the blue-dyed zinc-plated finish extends service life in harsh industrial environments, minimizing maintenance and replacement costs.
• High-strength Class 10.9 steel construction with Rockwell C32 hardness provides excellent durability and resistance to wear, ensuring long-term structural integrity.
• Optimized partially threaded design with a minimum 30mm thread length offers secure clamping force where needed while allowing flexibility in assembly.
• Precision external hex drive and head design enables easy installation and high torque application with standard tools, improving assembly efficiency.
• Coarse metric thread (M12 x 1.75mm) facilitates quick engagement and reduces cross-threading risks, speeding up installation in time-sensitive projects.
• Full compliance with international standards including ISO 4014 DIN 931 ensures interchangeability and reliability in global engineering applications.

Professional Applications & Engineering Value

This M12 hex head screw is engineered to address common industrial challenges such as vibration loosening, corrosion degradation, and high-load demands. The Class 10.9 steel material, combined with a Rockwell C32 hardness rating, provides exceptional resistance to shear and tensile forces, making it ideal for heavy-duty machinery, construction frameworks, and structural assemblies. The blue-dyed zinc-plated finish not only offers visual identification but also enhances corrosion resistance in outdoor or chemically aggressive environments. With its partially threaded configuration and coarse metric thread, it ensures rapid installation and reliable clamping in applications where full threading is unnecessary, reducing material costs without compromising performance. These features make it a preferred choice for engineers seeking durable, compliant, and easy-to-install industrial fasteners.

Specification Summary & Compliance
