Professional Applications & Engineering Value

This 1/2"-13 UNC coarse thread carriage bolt is engineered to address critical challenges in industrial and construction settings. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor structures, marine equipment, and chemical processing facilities where moisture and corrosive agents are present. The square neck design effectively locks the bolt into place during tightening, preventing rotation and reducing assembly time in wood-to-metal or timber frame applications. With a fully threaded shank and coarse thread profile, it ensures quick installation and reliable holding power in soft materials like wood or plastic, while the rounded head offers a clean finish and reduces snagging risks. Ideal for heavy-duty fastening in agricultural machinery, trailer assemblies, and structural frameworks, this bolt delivers durability and compliance with ASME B18.5 standards for consistent performance.
