Professional Applications & Engineering Value

These high-strength socket head cap screws deliver exceptional engineering value in demanding industrial environments where reliability is paramount. The Black-Oxide alloy steel construction provides superior corrosion resistance, making them ideal for machinery, automotive assemblies, and heavy equipment applications exposed to moisture and chemicals. The fine 1.5mm pitch metric threading ensures superior vibration resistance and precise clamping force distribution, critical for dynamic load applications. With their 10mm hex drive and standard socket head profile, these fasteners allow for high-torque installation in confined spaces, while the Class 12.9 strength rating guarantees performance under extreme mechanical stress. The partially threaded design optimizes stress distribution, preventing thread stripping and ensuring long-term joint integrity in critical connections.

Specification Summary & Compliance

This M12 x 1.5mm socket head cap screw features precise Class 5g6g thread fit tolerance according to ISO metric standards, ensuring consistent threading performance. The fastener complies with DIN 912/ISO 21269 manufacturing specifications for dimensional accuracy and mechanical properties. Regulatory compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, making them suitable for global industrial applications. The combination of 40mm total length with 36mm minimum thread length provides optimal engagement characteristics while maintaining the structural integrity required for Class 12.9 high-strength applications.
