Professional Applications & Engineering Value

This M6 socket head cap screw is engineered to solve critical challenges in precision machinery, automotive assemblies, and chemical processing equipment. The 316 stainless steel material provides exceptional resistance to corrosion from chlorides and acidic environments, significantly extending service life. The ultra-low profile socket head is a key design feature, enabling flush mounting in compact designs where standard head height is prohibitive. Combined with a Class 6g metric thread and coarse M6x1mm pitch, it ensures rapid assembly and a robust, reliable clamp force that resists loosening under dynamic loads and vibration, making it a trusted component for high-performance industrial applications.

Specification Summary & Compliance

This screw features an M6x1mm coarse metric thread with a Class 6g tolerance for precision fit. Key dimensional specifications include a 10mm head diameter, 16mm length, and a 4mm hex drive. It is manufactured from 316 Stainless Steel with a hardness of Rockwell B70 and a tensile strength of 70,000 PSI. This product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
