Professional Applications & Engineering Value
This Grade 5 black-oxide steel carriage bolt is engineered to address common industrial challenges such as joint failure and corrosion in structural assemblies. The fully threaded UNC coarse thread design ensures rapid installation and high clamping force in wood-to-metal and heavy machinery applications. Its square neck securely locks into materials, eliminating rotation during torque application—critical for conveyor systems, trailer beds, and agricultural equipment. The black-oxide coating provides a durable barrier against rust, reducing maintenance in outdoor or humid conditions. With a rounded head for smooth surface contact, it minimizes snagging risks while maintaining 120,000 psi tensile strength for reliable performance under dynamic loads.
Specification Summary & Compliance
This carriage bolt adheres to Class 2A thread fit and UNC coarse thread standards for precise dimensional accuracy. Manufactured in accordance with ASME B18.5 and SAE J429 specifications, it ensures consistent mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of restricted hazardous substances for safe industrial use.
