Key Features & Benefits at a Glance
- Exceptional corrosion resistance with hot-dipped galvanized steel coating, ideal for outdoor and harsh industrial environments.
- High tensile strength of 60,000 PSI ensures reliable load-bearing capacity for heavy-duty structural applications.
- Secure anti-rotation design with a square neck that locks into materials, preventing loosening under vibration.
- Coarse UNC threading (3/8"-16) provides faster installation and better performance in wood and soft materials.
- Partially threaded shank allows for precise clamping force control and reduced stress concentration.
- Wide rounded head profile distributes pressure evenly, minimizing surface damage and improving aesthetics.
- Compliance with ASTM A307, ASTM A153, and ASME B18.5 guarantees consistent quality and engineering reliability.
Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt is engineered to address common challenges in construction, agricultural machinery, and industrial assembly where corrosion resistance and structural integrity are critical. The Grade 2 classification and 60,000 PSI tensile strength ensure it withstands heavy loads and dynamic stresses, while the square neck design eliminates spinning during tightening, saving installation time and enhancing safety. Its partial threading and coarse UNC thread make it ideal for wood-to-metal connections and framing applications, providing superior grip and durability in demanding environments. By combining robust material properties with precise manufacturing standards, this bolt delivers long-term performance in bridges, fencing, and equipment that requires weather-resistant fastening solutions.
Specification Summary & Compliance
This carriage bolt features a 3/8"-16 UNC coarse thread with Class 2A thread fit for standard tolerance and easy assembly. It complies with ASTM A307 for low-carbon steel bolts, ASTM A153 for zinc coating, and ASME B18.5 for dimensional consistency. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
