Professional Applications & Engineering Value
These hot-dipped galvanized steel carriage bolts deliver critical engineering solutions for industrial applications where corrosion resistance and structural integrity are paramount. The 5/8"-11 UNC coarse thread configuration ensures rapid installation in wood-to-metal and structural steel connections, while the square neck design eliminates rotation issues common in high-vibration environments. The fully threaded construction provides maximum adjustability in construction, agricultural equipment, and transportation infrastructure. With Grade 2 strength classification and 60,000 PSI tensile strength, these bolts maintain secure fastening under substantial loads, making them ideal for structural framing, trailer assemblies, and outdoor installations where environmental exposure demands superior protection against rust and degradation.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit tolerance and UNC coarse thread specification with 5/8"-11 threading. Manufacturing complies with ASTM A307 for chemical and mechanical properties, ASTM A153 for zinc coating requirements, and ASME B18.5 for dimensional standards. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental regulatory adherence for global industrial applications.
