Professional Applications & Engineering Value
These M18 hex head screws deliver exceptional engineering value across industrial applications where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction provides reliable strength for heavy machinery assembly, structural steel connections, and equipment manufacturing. The fine 1.5mm thread pitch offers superior resistance to loosening under dynamic loads, while the zinc plating protects against corrosion in challenging environments. The partially threaded design ensures optimal clamping force distribution, making these metric hex bolts ideal for applications requiring precise unthreaded shank sections. With 70mm length and external hex drive, they provide both accessibility and performance for maintenance-critical installations.
Specification Summary & Compliance
Manufactured to ISO 8765 (DIN 960) specifications with Class 6h thread fit precision. These partially threaded screws feature M18 x 1.5mm fine thread configuration with 42mm minimum thread length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Class 8.8 strength grade ensures consistent performance meeting international industrial standards for quality and safety.
