Professional Applications & Engineering Value
This zinc-plated steel carriage bolt is engineered to address common challenges in industrial fastening, such as vibration-induced loosening and corrosion. The square neck design locks securely into materials, eliminating the need for additional locking mechanisms and speeding up assembly in wood-to-metal and structural steel connections. With a Rockwell B70 hardness and 60,000 psi tensile strength, it withstands heavy loads in construction, agricultural equipment, and transportation applications. The fully threaded UNC coarse pattern ensures deep engagement in soft materials, while the zinc plating provides a protective barrier against rust, making it ideal for outdoor and high-moisture environments. Its compliance with ASTM A307, SAE J429, and ASME B18.5 standards ensures reliability and safety in critical engineering projects.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit and UNC coarse threading (7/16"-14) for consistent performance. It meets manufacturing specifications under ASTM A307, SAE J429, and ASME B18.5, ensuring dimensional accuracy and mechanical properties. Additionally, it is RoHS 3 (2015/863/EU) Compliant, adhering to environmental regulations for restricted hazardous substances.
