Professional Applications & Engineering Value
This Grade 2 carriage bolt delivers exceptional engineering value through its zinc-plated steel construction and fully threaded UNC coarse thread design. The combination of 60,000 psi tensile strength and Rockwell B70 hardness addresses critical industrial challenges including structural fatigue, material deformation, and environmental degradation. The square neck carriage bolt configuration provides superior anti-rotation performance in wood-to-metal and structural steel applications, preventing loosening under dynamic loads. These industrial fasteners are engineered for machinery assembly, construction frameworks, transportation equipment, and agricultural implements where vibration resistance and long-term reliability are paramount. The right-hand thread direction and Class 2A thread fit ensure compatibility with standard industrial components while maintaining installation efficiency.
Specification Summary & Compliance
This carriage bolt maintains precise Class 2A thread fit tolerances with UNC coarse thread specifications (10-24 thread size). Manufacturing complies with ASTM A307, SAE J429 Grade 2, and ASME B18.5 standards. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. Dimensional specifications include 2" length, 0.469" head diameter, and 0.19" screw diameter with square neck measuring 0.2" width and 0.13" length.
