Professional Applications & Engineering Value
This Grade 5 carriage bolt delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, agricultural machinery, and construction applications exposed to environmental elements. The square neck design eliminates the need for secondary locking mechanisms by embedding securely into materials, preventing rotation during torque application and long-term use. With full UNC threading and Class 3A thread fit, installation efficiency is maximized while maintaining precise tolerances for heavy-load connections in structural frameworks, trailer assemblies, and industrial equipment where 120,000 psi tensile strength ensures reliable performance under sustained mechanical stress.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit and UNC coarse threading (1/2"-13) for optimal engagement. Complies with ASME B18.5 and SAE J429 specifications for Grade 5 carriage bolts, ensuring consistent quality and performance. Meets environmental regulations including RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant standards for restricted substance control.
