Professional Applications & Engineering Value
These hot-dipped galvanized steel carriage bolts deliver critical engineering solutions where corrosion resistance and structural reliability are paramount. The square neck design effectively locks into wood or metal surfaces, eliminating rotation during tightening—saving labor time in construction, agricultural equipment, and transportation infrastructure. With UNC coarse threading and Class 2A thread fit, they provide rapid assembly in timber framing, trailer beds, and structural connections while maintaining 60,000 PSI tensile strength. The thick zinc coating from hot-dip galvanizing offers long-term protection against rust in bridges, marine environments, and outdoor storage systems, reducing maintenance cycles and lifecycle costs.
Specification Summary & Compliance
This 3/4"-10 carriage bolt features precise Class 2A thread fit with UNC coarse threading and full threading along its 4" length. Manufactured to ASTM A307 and ASME B18.5 specifications, it ensures dimensional accuracy and mechanical consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material restrictions adherence for industrial and international supply chains.
