Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt delivers critical engineering solutions for industrial and construction applications where vibration resistance and structural integrity are paramount. The square neck design effectively prevents rotation during torque application, making it ideal for wood-to-metal connections and structural framing where access is limited to one side. The UNC coarse threading provides superior holding power in softer materials while the zinc plating offers essential corrosion protection for outdoor equipment, agricultural machinery, and industrial assemblies. With its 120,000 psi tensile strength and Rockwell C25 hardness, this fastener maintains clamping force under dynamic loads, preventing joint failure in demanding environments from construction sites to manufacturing facilities.
Specification Summary & Compliance
This carriage bolt features precision Class 2A thread fit with 1/2"-13 UNC coarse threading and right-hand orientation. Manufactured to ASME B18.5 and SAE J429 Grade 5 standards, ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming responsible manufacturing practices and material safety for industrial applications worldwide.
