Professional Applications & Engineering Value
These M6 hex head screws deliver critical engineering solutions for industrial applications requiring heavy-duty metric fasteners. The Class 8.8 steel construction provides exceptional strength-to-weight ratio, while the coarse thread with 1mm pitch ensures rapid installation and resistance to vibration loosening in machinery, equipment frames, and structural assemblies. The external hex drive design allows for high torque application with standard tools, preventing stripping and ensuring consistent clamping force. Fully threaded along the 12mm length, these black steel screws maximize contact surface area, distributing stress evenly and preventing point failure in high-vibration environments common in manufacturing, automotive, and construction applications.
Specification Summary & Compliance
Manufactured to ISO 4017 standards (equivalent to DIN 933) with Class 6g thread tolerance for precision fit. These metric screws feature M6 x 1mm coarse thread configuration with right-hand threading and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Class 8.8 strength grade ensures consistent mechanical properties with Rockwell C21 hardness and 110,000 psi tensile strength meeting international fastener specifications.
