• Excellent wear resistance due to Rockwell C32 hardness, ensuring long service life and reduced maintenance requirements
• Maximum grip and holding power from fully threaded design, providing consistent clamping force along the entire 80mm length
• Quick and secure installation with external hex drive and standard 27mm head width for easy tool access and high torque application
• Precise thread engagement with Class 6g thread fit and M18x2.5 coarse thread spacing for fast assembly and vibration resistance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Interchangeable reliability through DIN 933 specification compliance, ensuring consistent performance across industrial applications

Professional Applications & Engineering Value

These M18 hex head screws deliver exceptional engineering value in heavy-duty industrial applications where failure is not an option. The Class 10.9 steel construction provides critical resistance to dynamic loads and shock impacts common in machinery assembly, structural steel connections, and equipment manufacturing. The fully threaded metric design ensures maximum thread engagement throughout the fastener length, eliminating weak points that can compromise structural integrity. With Rockwell C32 hardness, these black steel screws maintain their mechanical properties under continuous stress, while the coarse thread pitch facilitates rapid installation in time-sensitive production environments. The external hex drive configuration allows for high torque application without stripping, making them ideal for maintenance-critical applications where disassembly and reassembly are frequent requirements.

Specification Summary & Compliance

This metric hex head screw features precise Class 6g thread fit tolerance per ISO standards, ensuring consistent mating with corresponding nuts and threaded holes. Manufactured to DIN 933 specifications with M18x2.5 coarse thread profile and 80mm length. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. The right-hand thread direction and fully threaded configuration provide standardized installation across industrial applications requiring high tensile strength fastening solutions.
