Key Features & Benefits at a Glance
- Superior corrosion resistance with hot-dipped galvanized steel coating, ensuring long-term reliability in outdoor or humid environments.
- Enhanced load-bearing capability with Grade 2 classification and 60,000 psi tensile strength, suitable for heavy-duty structural applications.
- Secure anti-rotation design thanks to the square neck, which prevents spinning during installation and improves assembly efficiency.
- Wide compatibility and easy installation with UNC coarse threading and Class 2A fit, allowing for quick fastening in various materials.
- Consistent performance under stress due to Rockwell B70 hardness, reducing the risk of stripping or deformation.
- Full threading for versatile grip range, enabling use in applications where the entire bolt length needs engagement.
- Compliance with industry standards including ASTM A307 and ASME B18.5, ensuring quality and safety in professional settings.
Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt is engineered to address common challenges in industrial and construction settings, such as corrosion from weather exposure and the need for reliable, vibration-resistant fastening. The square neck design locks securely into materials, preventing rotation during torque application and simplifying installation in wood, metal, or composite structures. With a coarse UNC thread and Class 2A fit, it offers excellent grip in soft materials while maintaining alignment. The heavy-duty 5-inch length and full threading provide flexibility for thick assemblies, making it ideal for framing, machinery, and outdoor equipment where durability and compliance with ASTM A307 and other standards are critical for long-term performance.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional tolerances, including a Class 2A thread fit for consistent engagement and UNC 1/2"-13 coarse threading. It meets manufacturing specifications per ASTM A307 for low-carbon steel bolts and ASME B18.5 for dimensional standards. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for regulated industries.
