- High tensile strength of 60,000 psi and Grade 2 classification for reliable load-bearing in demanding applications.
- Easy installation and removal with fully threaded UNC coarse threading and right-hand direction, compatible with standard tools.
- Consistent dimensional accuracy with Class 2A thread fit, ensuring precise engagement and reduced risk of cross-threading.
- Durable material hardness rated at Rockwell B70, providing resistance to wear and deformation under stress.
- Compliance with major industry standards including ASTM A307, ASTM A153, and ASME B18.5, guaranteeing quality and interoperability.
Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt is engineered to address common industrial challenges such as corrosion, vibration loosening, and structural integrity. The square neck design locks securely into materials, preventing rotation during torque application, which is critical in wood-to-metal connections and framing applications. With a coarse UNC thread and full threading, it offers quick assembly and high pull-out resistance, ideal for construction, agricultural equipment, and transportation infrastructure. The zinc coating from hot-dipping provides a thick barrier against moisture and chemicals, extending service life in outdoor or corrosive environments while maintaining Grade 2 strength for cost-effective, heavy-duty fastening solutions.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional tolerances, including a Class 2A thread fit for consistent performance and a 5/8"-11 UNC coarse thread size. It meets manufacturing specifications per ASTM A307 for low-carbon steel bolts, ASTM A153 for zinc coating, and ASME B18.5 for dimensional standards. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial and commercial uses.
