Professional Applications & Engineering Value

This M8 carriage bolt delivers critical engineering solutions for industrial fastening challenges where vibration resistance and long-term reliability are paramount. The zinc yellow-chromate plated steel construction provides superior corrosion protection in demanding environments, while the integrated square neck design eliminates rotational movement that can compromise joint integrity. With Class 8.8 strength rating (110,000 PSI tensile strength) and coarse thread pitch (1.25mm), these metric carriage bolts offer exceptional load-bearing capacity and faster installation in wood-to-metal applications, structural frameworks, and heavy equipment assembly. The combination of Rockwell C22 hardness and fully threaded configuration ensures consistent performance across varying material thicknesses while meeting ISO 8678 standards for dimensional precision.

Specification Summary & Compliance

This carriage bolt features M8 x 1.25mm coarse threading with Class 6g thread fit tolerance for precise engagement. The fastener maintains dimensional compliance with ISO 8678 specifications and achieves Class 8.8 mechanical properties (equivalent to 110,000 PSI tensile strength). Manufacturing incorporates Rockwell C22 hardness standards and right-hand thread direction with fully threaded configuration. The product meets international regulatory requirements including RoHS and REACH environmental compliance standards.
