• Optimized thread engagement with M12 coarse (1.75mm pitch) threads and Class 5g6g fit, enabling faster assembly and vibration resistance
• Versatile partial threading design allowing both secure fastening and alignment functions in machinery applications
• Global compliance assurance meeting DIN 912/ISO 4762 standards plus RoHS 3 and REACH environmental regulations
• Consistent hardness performance at Rockwell C37, maintaining structural integrity through repeated use cycles

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M12 socket head cap screws solve critical fastening challenges in heavy machinery, automotive assemblies, and precision equipment. The black-oxide alloy steel construction provides essential corrosion protection where lubricants or coatings might degrade, while the Class 12.9 strength rating prevents thread stripping and head deformation under high vibration loads. The partially threaded design offers dual functionality - fully engaged threads for maximum clamping force combined with unthreaded shank sections for precise component alignment. With DIN 912/ISO 4762 certification, these metric socket screws deliver guaranteed dimensional consistency for international engineering projects requiring interchangeable components.

Specification Summary & Compliance

Manufactured to Class 5g6g thread fit tolerance per metric standards with 1.75mm coarse pitch threading and 36mm minimum thread length. Full compliance with DIN 912/ISO 4762 dimensional specifications, RoHS 3 (2015/863/EU) hazardous substance restrictions, and REACH (EC 1907/2006) chemical safety regulations. The 130mm overall length with standard socket head profile ensures compatibility with existing 10mm hex drive tools and industry-standard installation procedures.
