Professional Applications & Engineering Value
This Grade 5 carriage bolt delivers critical engineering solutions for industrial and construction applications where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor structures, agricultural equipment, and material handling systems. The combination of UNC coarse threading and square neck design addresses common installation challenges by preventing rotation during torque application, particularly valuable in wood-to-metal connections and framing applications. The partially threaded configuration ensures optimal clamp force distribution while the 1/2"-13 thread size and 9" length make it ideal for heavy timber construction, trailer manufacturing, and industrial machinery assembly where high tensile strength and reliable performance under dynamic loads are required.
Specification Summary & Compliance
This carriage bolt maintains precision Class 3A thread fit with UNC coarse thread pattern (1/2"-13) and complies with ASME B18.5 dimensional standards. Manufacturing specifications include Rockwell C25 hardness and 120,000 psi tensile strength meeting Grade 5 requirements. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for regulated industrial applications.
