Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt delivers exceptional engineering value for industrial applications where vibration resistance and structural integrity are paramount. The square neck design eliminates the need for secondary locking mechanisms by preventing rotation during torque application, significantly reducing installation time in assembly line operations. The UNC coarse threading provides superior performance in softer materials and high-vibration environments, while the zinc-plated finish offers reliable corrosion protection for outdoor equipment, agricultural machinery, and structural steel connections. With its fully threaded configuration and Class 3A thread fit, this fastener ensures consistent clamping force distribution across the entire engagement length, making it ideal for heavy-duty construction, transportation equipment, and industrial machinery where joint integrity cannot be compromised.
Specification Summary & Compliance
This carriage bolt maintains precise dimensional accuracy with Class 3A thread fit and UNC coarse threading (5/8"-11) specifications. Manufacturing complies with ASME B18.5 standards SAE J429, ensuring consistent quality and performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant (06/10/2022 224 SVHC), meeting current environmental regulations for industrial use worldwide.
