Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt delivers critical performance in demanding environments where corrosion resistance and structural reliability are paramount. The rounded head with square neck design eliminates rotation during tightening, making it ideal for wood-to-metal connections in construction, agricultural equipment, and utility structures. Its 1/2"-13 UNC coarse thread and Class 2A fit ensure quick installation and sustained clamping force, while the partial threading configuration provides an unthreaded bearing surface that resists shear forces. With 60,000 PSI tensile strength and Rockwell B70 hardness, it maintains fastener integrity in heavy-duty applications such as trailer assemblies, bridge decking, and industrial framing, where weather exposure and dynamic loads are constant challenges.
Specification Summary & Compliance
This carriage bolt features inch system dimensions with a 1/2"-13 UNC coarse thread and Class 2A thread fit for standard tolerance. It is manufactured in compliance with ASTM A307 (Grade 2), ASTM A153 (zinc coating), and ASME B18.5 dimensional standards. The product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations for industrial use worldwide.
