• Optimized thread engagement with M16x2mm coarse threads and Class 6g fit, ensuring secure fastening and vibration resistance
• Versatile installation flexibility through partially threaded design, allowing precise clamping force distribution
• Enhanced material durability with Rockwell C37 hardness, maintaining structural integrity under repeated loading
• Global standard compliance meeting DIN 912/ISO 4762 specifications for international project compatibility

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M16 socket head cap screws solve critical fastening challenges in heavy machinery, automotive assemblies, and structural frameworks. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Class 12.9 strength rating required for high-vibration environments. The partially threaded metric design allows engineers to concentrate clamping force precisely where needed, preventing joint loosening in dynamic load conditions. With coarse thread pitch and right-hand thread direction, installation efficiency is maximized in production line settings while the 170mm length accommodates substantial material thicknesses commonly encountered in industrial equipment manufacturing.

Specification Summary & Compliance

This socket head cap screw maintains Class 6g thread fit tolerance per metric standards with 43mm minimum thread length and 2mm coarse thread pitch. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and ISO 898-1 for mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental and safety regulations for industrial components.
