Professional Applications & Engineering Value
These Grade 5 carriage bolts with zinc-flake coated steel construction address critical challenges in industrial fastening where corrosion resistance and structural integrity are paramount. The square neck design provides positive locking against rotation during torque application, eliminating the need for additional anti-rotation components in assembly. The coarse UNC threading ensures rapid installation in wood-to-metal and structural steel applications while maintaining 120,000 PSI tensile strength for heavy load requirements. The combination of Rockwell C25 hardness and premium surface treatment makes these fully threaded carriage bolts ideal for construction equipment, agricultural machinery, trailer manufacturing, and structural frameworks where vibration resistance and long-term reliability are essential.
Specification Summary & Compliance
