Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M12 socket head cap screws deliver critical performance where failure is not an option. The blue-dyed zinc-plated alloy steel construction provides dual protection against corrosion while maintaining the Class 12.9 strength rating essential for heavy machinery, automotive assemblies, and structural frameworks. The fully threaded design with coarse thread pitch ensures rapid installation and superior clamping force distribution, while the hex socket drive prevents cam-out issues common in high-torque applications. These metric socket screws solve common engineering challenges by combining maximum tensile strength with consistent dimensional accuracy per DIN 912/ISO 4762 standards, making them ideal for precision equipment manufacturing and maintenance operations requiring reliable industrial fasteners.

Specification Summary & Compliance

This socket head cap screw maintains precise Class 5g6g thread fit tolerance according to metric thread standards, ensuring consistent performance across applications. Manufacturing strictly adheres to DIN 912/ISO 4762 specifications for dimensional accuracy, including 18mm head diameter, 12mm head height, and 20mm length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and market accessibility. The right-hand thread direction and fully threaded rod type provide uniform stress distribution and maximum thread engagement capacity.
