Professional Applications & Engineering Value

These M6 socket head cap screws deliver critical engineering solutions where high tensile strength and precision threading are paramount. The black-oxide alloy steel construction addresses common industrial challenges including vibration-induced loosening, corrosion in harsh environments, and repetitive stress fatigue. The coarse 1mm pitch thread provides faster assembly while maintaining secure fastening in materials where fine threads might strip. Engineered for heavy-duty applications such as machinery frames, automotive assemblies, and industrial equipment, these Class 12.9 fasteners ensure reliable performance under extreme loads. The standard socket head profile with 5mm hex drive allows for compact installations in confined spaces while providing superior torque transmission compared to conventional screw heads.

Specification Summary & Compliance

Manufactured to precise Class 5g6g thread fit tolerances ensuring consistent engagement and alignment. Fully compliant with DIN 912/ISO 4762 manufacturing specifications for dimensional accuracy and mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming restriction of hazardous substances. The fully threaded M6 x 1mm coarse thread design maintains standard metric specifications for universal compatibility across industrial applications.
