Professional Applications & Engineering Value
This M22 hex head screw delivers exceptional engineering value for heavy-duty industrial applications where reliability is paramount. The Class 8.8 steel construction provides the necessary structural integrity for machinery assembly, construction projects, and equipment manufacturing that demand sustained performance under stress. The coarse metric threading (2.5mm pitch) ensures rapid installation and superior resistance to vibration loosening, while the zinc plating offers critical protection against corrosion in challenging environments. The external hex drive design allows for high-torque application, making these fully threaded fasteners ideal for applications requiring maximum clamping force and uniform stress distribution across the entire 70mm length.
Specification Summary & Compliance
This metric hex head screw features precise M22x2.5 coarse threading with Class 6h thread fit tolerance for optimal engagement. Manufactured in compliance with ISO 4017 specifications (equivalent to DIN 933), ensuring dimensional accuracy and mechanical performance. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial applications requiring strict compliance standards.
