Professional Applications & Engineering Value
These Grade 5 zinc-plated steel carriage bolts deliver critical engineering advantages for industrial fastening applications where vibration resistance and corrosion protection are paramount. The fully threaded UNC coarse thread design ensures maximum grip length and faster assembly in wood-to-metal and structural steel connections. The integrated square neck beneath the rounded head provides positive locking against rotation during torque application, eliminating the need for additional locking mechanisms. This combination of 120,000 PSI tensile strength and Rockwell C25 hardness makes these carriage bolts ideal for heavy equipment, trailer manufacturing, construction frameworks, and agricultural machinery where reliable fastening solutions must withstand dynamic loads and environmental exposure.
