Professional Applications & Engineering Value

These Class 12.9 socket head cap screws deliver critical performance advantages in demanding applications where failure is not an option. The alloy steel construction combined with blue-dyed zinc plating creates a robust fastener that withstands both mechanical stress and environmental corrosion. The M4 x 0.7mm coarse thread configuration ensures rapid installation while maintaining secure connections in vibration-prone equipment. Engineering teams specify these metric socket screws for precision machinery, automotive assemblies, and industrial automation systems where the Class 5g6g thread fit guarantees consistent performance in tapped holes. The 12mm length provides optimal engagement depth for medium-thickness materials, making these fasteners ideal for compact assemblies requiring high clamp load retention.

Specification Summary & Compliance

This socket head cap screw features precise Class 5g6g thread fit tolerance per ISO metric standards, ensuring compatibility with standard M4 threaded components. Manufacturing strictly adheres to DIN 912/ISO 4762 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. The right-hand coarse thread with 0.7mm pitch provides optimal engagement characteristics for industrial applications requiring rapid assembly and disassembly.
