Professional Applications & Engineering Value
This M8 hex head screw delivers critical engineering advantages through its black phosphate steel construction and Class 10.9 strength grade. The flanged design provides superior load distribution, eliminating washer requirements while maintaining clamping force in industrial machinery, automotive assemblies, and structural frameworks. With partial threading and coarse metric thread pitch, it resists vibration loosening and enables rapid installation in high-volume production environments. The external hex drive ensures reliable torque transmission, while the black phosphate surface treatment offers corrosion protection in humid or chemically exposed applications, making it ideal for OEM and MRO operations demanding consistent performance.
Specification Summary & Compliance
Manufactured to precise Class 6g thread fit tolerances with M8 x 1.25 mm coarse thread specifications. Complies with ASME B18.2.3.9M dimensional standards and maintains RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance. Features 60mm length with 22mm minimum thread length and 18mm flange diameter for consistent performance across industrial applications.
