Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt delivers exceptional engineering value for heavy-duty industrial applications where vibration resistance and structural integrity are critical. The combination of 3/4"-10 UNC coarse threading with Class 3A fit ensures precise engagement in wood, metal, and composite materials, while the square neck design provides superior anti-rotation performance that eliminates the need for additional locking mechanisms. The zinc-plated steel construction offers reliable corrosion protection for outdoor equipment, construction frameworks, and agricultural machinery. With its 120,000 psi tensile strength and Rockwell C25 hardness, this fastener maintains structural integrity under extreme loads and harsh operating conditions, making it ideal for structural connections, trailer assemblies, and heavy equipment manufacturing where failure is not an option.
Specification Summary & Compliance
This carriage bolt features precision 3/4"-10 UNC coarse threading with Class 3A fit tolerance for optimal thread engagement. Manufactured to Grade 5 specifications with 120,000 psi tensile strength and Rockwell C25 hardness. Complies with ASME B18.5 dimensional standards and SAE J429 material specifications. Meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements for restricted substances.
