• Corrosion-resistant black-oxide finish on alloy steel base material offers enhanced durability in industrial environments
• Fully threaded design allows for maximum adjustability and uniform clamping force distribution along the entire 40mm length
• Standardized metric coarse thread (M6 x 1mm) ensures compatibility with existing industrial equipment and simplifies inventory management
• Regulatory compliance with RoHS 3 and REACH standards makes these screws suitable for global manufacturing and export applications

Professional Applications & Engineering Value

These M6 socket head cap screws deliver critical engineering advantages in demanding industrial applications where space constraints and vibration resistance are primary concerns. The black-oxide alloy steel construction provides superior corrosion protection while maintaining the 140,000 psi tensile strength necessary for heavy machinery, automotive assemblies, and precision equipment. The ultra-low profile head design solves clearance issues in compact assemblies without compromising the 4mm hex drive's torque transmission capability. With Class 5g6g thread fit and consistent 1mm coarse pitch threading, these metric fasteners ensure reliable engagement in high-vibration environments, reducing maintenance requirements and preventing costly downtime in production equipment and industrial machinery.

Specification Summary & Compliance

This socket head cap screw features precision M6 x 1mm metric coarse threading with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and reliable performance. The 40mm length maintains tight tolerance control from -0.127mm to +0.127mm for consistent installation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making these fasteners suitable for restricted substance-controlled applications across global industrial markets.
