• Optimized thread design with coarse 1.5mm pitch enables faster assembly and better resistance to loosening
• Class 12.9 strength certification guarantees consistent mechanical properties for critical applications
• Partially threaded shank design allows for precise clamping force distribution and reduced stress concentration
• Full regulatory compliance with DIN 912, RoHS 3 and REACH standards ensures global acceptance and environmental safety

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M10 socket head cap screws combine Class 12.9 alloy steel construction with black-oxide surface treatment to address critical engineering challenges. The coarse thread pitch (1.5mm) significantly reduces installation time while maintaining vibration resistance in heavy machinery, automotive assemblies, and structural frameworks. With 32mm thread length and partial threading, these fasteners provide optimal stress distribution across joined components, preventing material fatigue in high-cycle applications. The hex socket drive system ensures maximum torque transmission without cam-out, making them ideal for confined spaces where wrench clearance is limited. These metric fasteners deliver reliable performance in manufacturing equipment, robotics, and precision tooling where failure is not an option.

Specification Summary & Compliance

This socket head cap screw maintains precise Class 5g6g thread fit according to ISO metric standards, ensuring consistent engagement and load distribution. Manufacturing strictly adheres to DIN 912 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits. With Rockwell C37 hardness and verified 170,000 PSI tensile strength, these fasteners meet the highest quality standards for industrial and engineering applications worldwide.
