Key Features & Benefits at a Glance
- Superior corrosion resistance with hot-dipped galvanized steel coating, ideal for outdoor and harsh industrial environments.
- Enhanced installation security due to the square neck design that prevents rotation during tightening, ensuring reliable fastening.
- High tensile strength of 60,000 psi (Grade 2) provides dependable load-bearing capacity for heavy-duty applications.
- Rockwell B70 hardness offers excellent durability and resistance to wear and deformation under stress.
- Coarse UNC threading with Class 2A fit allows for quick assembly and disassembly, reducing installation time and labor costs.
- Partially threaded shank concentrates thread engagement where needed, improving grip and shear strength in structural connections.
- Compliance with ASTM A307, ASME B18.5, RoHS 3, and REACH ensures consistent quality, safety, and environmental standards for global industrial use.
Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt is engineered to address common challenges in construction, agricultural machinery, and infrastructure projects where corrosion resistance and structural integrity are critical. The wide rounded head and square neck work together to prevent spinning during installation, simplifying assembly in wood-to-metal or timber framing applications. With a 1/2"-13 UNC coarse thread and partial threading, it ensures secure fastening in dynamic load conditions, reducing the risk of loosening. The Grade 2 strength rating and robust material composition make it suitable for heavy-duty uses like trailer building, bridge components, and industrial equipment, offering long-term reliability and reduced maintenance needs.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and UNC coarse threading per ASME B18.5. It meets ASTM A307 specifications for low-carbon steel bolts and is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances. The product's 14-inch length, 1/2"-13 thread size, and material properties align with industrial requirements for reliability and safety.
