• Superior corrosion resistance provided by the black protective coating, extending service life in harsh industrial environments
• Optimized torque transmission through the external hex drive design and 19mm head width for secure installation and removal
• Precision threading consistency with Class 6h thread fit and M12x1.75mm coarse pitch for quick assembly and vibration resistance
• Enhanced durability from Rockwell C32 hardness steel construction, maintaining structural integrity under repeated stress
• Full-threaded design ensures maximum grip length and uniform stress distribution along the entire 20mm shaft
• Global compliance assurance meeting ISO 4017/DIN 933 standards with RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

These M12 hex head screws deliver critical engineering solutions for industrial assembly challenges where high-strength fastening and environmental durability are paramount. The Class 10.9 steel construction provides exceptional resistance to mechanical stresses in heavy machinery, structural frameworks, and automotive components. The corrosion-resistant black coating protects against oxidation and chemical exposure in manufacturing facilities, outdoor equipment, and marine applications. With coarse metric threading (M12x1.75mm) and external hex drive, these fasteners enable rapid installation and secure clamping force in high-vibration environments. The fully threaded design ensures consistent engagement across the entire 20mm length, distributing load evenly and preventing joint failure in critical connections.

Specification Summary & Compliance

Manufactured to ISO 4017/DIN 933 specifications with Class 6h thread tolerance for precision fit. The metric coarse thread (M12x1.75mm) with right-hand direction ensures compatibility with standard industrial components. These hex head screws maintain Rockwell C32 hardness and 150,000 psi tensile strength throughout the 20mm fully threaded length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, confirming safe use across regulated industries.
