Professional Applications & Engineering Value
These M8 carriage bolts deliver critical engineering solutions for industrial assembly challenges. The zinc yellow-chromate plated steel construction provides exceptional corrosion protection in demanding environments, while the integrated square neck design eliminates rotation issues during torque application - a common problem in wood-to-metal and structural connections. The fully threaded metric configuration with coarse 1.25mm pitch ensures rapid installation in production environments and maintains secure fastening under vibration. With Class 8.8 strength rating and precise Class 6g thread fit, these carriage bolts offer reliable performance in heavy machinery, construction frameworks, transportation equipment, and agricultural implements where anti-loosening and corrosion resistance are paramount.
Specification Summary & Compliance
Manufactured to exact ISO 8678 specifications with Class 6g thread tolerance for consistent dimensional accuracy. Features M8x1.25mm coarse thread with right-hand threading direction and fully threaded design. The zinc yellow-chromate plating provides superior surface protection, while the square neck (8.58mm width, 3mm length) ensures positive anti-rotation performance. Complies with international metric standards and meets Class 8.8 mechanical properties with verified 110,000 psi tensile strength and Rockwell C22 hardness rating.
