- Optimized torque transmission through external hex drive and flange design (26.6mm diameter) ensuring secure fastening and vibration resistance
- Precision threading compatibility with M12x1.75mm coarse threads and Class 6g fit for easy installation and consistent engagement
- Enhanced durability from Rockwell C32 hardness that maintains structural integrity under repeated stress and wear
- Full-threaded design providing maximum grip length and uniform stress distribution across the entire 30mm length
- Regulatory compliance assurance meeting ISO 898-1 DIN 6921 standards and REACH certification for global industrial acceptance
Professional Applications & Engineering Value
These M12 hex head screws deliver critical engineering solutions where vibration resistance, corrosion protection, and high tensile strength are paramount. The zinc yellow-chromate plated steel construction combats environmental degradation in outdoor equipment, machinery assemblies, and structural frameworks. The flanged design eliminates need for separate washers while distributing clamping force evenly, preventing surface damage and maintaining joint integrity. With Class 10.9 strength and coarse threading, these fully threaded screws provide rapid installation in steel structures, automotive components, and heavy-duty manufacturing equipment where 150,000 PSI tensile strength ensures long-term reliability under dynamic loads.
Specification Summary & Compliance
Manufactured to ISO 898-1 DIN 6921 specifications with Class 6g thread fit tolerance for precision engagement. The M12x1.75mm coarse thread follows standard metric spacing while the 30mm length provides consistent threading depth. Compliant with REACH (EC 1907/2006) regulations regarding substance restrictions, ensuring environmental and workplace safety standards are met for industrial distribution and use.
