Professional Applications & Engineering Value
This M8 carriage bolt delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides exceptional corrosion protection for outdoor equipment, agricultural machinery, and construction applications exposed to weather elements. The square neck design securely locks into materials during installation, eliminating rotation issues common in wood-to-metal and structural steel connections. With fully threaded coarse pitch configuration and Class 8.8 strength, these metric fasteners ensure rapid assembly while maintaining reliable clamping force in heavy-duty industrial settings, from conveyor systems to structural frameworks requiring repeated disassembly and reassembly.
Specification Summary & Compliance
Manufactured to precise metric dimensions with M8 x 1.25mm coarse thread and Class 6g thread tolerance. The fastener meets ISO 8678 international standards for carriage bolts and features Rockwell C22 hardness with 110,000 psi tensile strength. The zinc yellow-chromate plating provides RoHS and REACH compliant corrosion protection, while the square neck and rounded head design ensure proper installation according to industrial fastening specifications.
