• Superior durability and wear resistance thanks to Rockwell C32 hardness steel construction
• Maximum grip and holding power achieved through fully threaded design along the entire 40mm length
• Easy installation and removal with standard 24mm external hex head driving style
• Precise thread engagement with Class 6g thread fit ensuring consistent fastening in coarse (2mm pitch) metric threads
• Broad industrial compatibility through compliance with ISO 4017 and DIN 933 standards
• Environmentally responsible manufacturing meeting RoHS 3 and REACH regulatory requirements

Professional Applications & Engineering Value

This M16 hex head screw delivers critical engineering solutions for heavy-duty industrial applications where failure is not an option. The Class 10.9 steel construction provides exceptional resistance to vibration loosening and structural fatigue, making it ideal for machinery assembly, structural steel connections, and automotive components. The fully threaded metric design ensures maximum thread engagement throughout the fastener length, distributing stress evenly and preventing premature failure. With its coarse thread pitch and external hex drive, installation is rapid and secure even in challenging environments. The combination of 150,000 PSI tensile strength and Rockwell C32 hardness makes this fastener particularly valuable for applications requiring repeated disassembly and reassembly without performance degradation.

Specification Summary & Compliance

This metric hex head screw features M16x2mm coarse threads with Class 6g thread fit tolerance ensuring precise mating with standard nuts and threaded holes.
