Professional Applications & Engineering Value
This Grade 2 zinc-plated steel carriage bolt delivers exceptional engineering value in structural applications where vibration resistance and long-term reliability are critical. The square neck design provides superior anti-rotation performance, eliminating the need for additional locking mechanisms in wood-to-metal connections, structural framing, and heavy equipment assembly. The partially threaded configuration with 6" minimum thread length ensures optimal clamping force distribution, while the coarse UNC threading enables rapid installation in time-sensitive industrial projects. The zinc-plated finish offers reliable corrosion protection, making these carriage bolts ideal for outdoor structures, agricultural equipment, and construction applications where environmental exposure is a concern.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse threading (1/2"-13) for consistent performance. This carriage bolt complies with ASTM A307, SAE J429 Grade 2, and ASME B18.5 specifications, ensuring mechanical properties and dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for hazardous substance restrictions.
