Professional Applications & Engineering Value
This heavy-duty carriage bolt delivers exceptional engineering value through its zinc-plated steel construction and specialized design features. The square neck provides critical anti-rotation capability, eliminating the need for additional locking mechanisms in wood-to-metal and structural connections. The coarse UNC threading ensures rapid installation in timber, construction frameworks, and industrial equipment while maintaining superior pull-out resistance. With partial threading optimizing the grip length, this fastener prevents thread damage in soft materials while providing secure clamping force. The combination of Grade 2 strength classification and 60,000 psi tensile strength makes it ideal for structural applications in construction, heavy equipment, and transportation industries where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This carriage bolt features precision UNC coarse threading with Class 2A thread fit tolerance for reliable engagement. The fastener meets rigorous industry standards including ASTM A307, SAE J429, and ASME B18.5 specifications for dimensional accuracy and mechanical properties. Environmental compliance is assured through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certification, making it suitable for regulated applications across multiple industries.
