Professional Applications & Engineering Value

These M6 socket head cap screws deliver critical engineering solutions where high-strength fastening meets precision requirements. The black-oxide alloy steel construction provides superior protection against oxidation and wear in industrial environments, while the Class 12.9 strength rating ensures reliable performance under extreme mechanical loads. The partially threaded design allows for precise clamping force distribution in machinery, automotive components, and heavy equipment assemblies. With standard hex socket drive compatibility, these screws enable efficient installation in confined spaces where wrench clearance is limited. The coarse thread pitch facilitates rapid assembly in production environments while maintaining vibration resistance in dynamic applications.

Specification Summary & Compliance

This metric socket head cap screw features M6 x 1 mm coarse threads with Class 5g6g thread fit tolerance according to ISO standards. The fastener maintains dimensional compliance with DIN 912/ISO 4762 specifications for socket head cap screws, ensuring precise head geometry and drive compatibility. Manufacturing and material composition adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances. The 55 mm length with 24 mm minimum thread length provides standardized engagement for reliable joint integrity across industrial applications.
