- Optimized thread engagement with UNC coarse threading and Class 3A fit, ensuring secure fastening and reduced cross-threading risk.
- High material durability from Rockwell C25 hardness, providing excellent resistance to wear and deformation.
- Versatile full-thread design allowing for flexible nut placement along the entire 9-1/2" length.
- Broad compatibility with Grade 5 strength classification, meeting rigorous ASME B18.5 and SAE J429 standards.
Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt is engineered to address critical challenges in heavy machinery, construction, and transportation equipment assembly. The square neck securely locks into materials, eliminating rotation during installation—a common frustration with standard bolts. Its UNC coarse threads and Class 3A fit provide rapid assembly and high vibration resistance, reducing maintenance needs in dynamic load conditions. The zinc plating offers a cost-effective barrier against rust and corrosion, making it suitable for outdoor or high-moisture environments. With a 120,000 psi tensile strength and full threading, it ensures uniform stress distribution and reliable performance in demanding structural applications, from trailer hitches to steel frame connections.
Specification Summary & Compliance
This carriage bolt features a 5/8"-11 UNC coarse thread with Class 3A thread fit for precise dimensional accuracy. It is manufactured from zinc-plated steel and complies with ASME B18.5 and SAE J429 standards for Grade 5 fasteners. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations.
