• Square neck design prevents rotation during installation and use, offering secure fastening without the need for additional locking mechanisms.
• Fully threaded UNC coarse spacing allows for quick assembly and disassembly, improving efficiency in time-sensitive projects.
• Class 2A thread fit ensures consistent and precise engagement with nuts, reducing the likelihood of cross-threading and ensuring smooth installation.
• Rockwell C25 hardness enhances durability and wear resistance, making it suitable for heavy-duty applications where abrasion is a concern.
• Compliance with ASME B18.5 and SAE J429 standards guarantees quality and interoperability, providing peace of mind for engineers and procurement specialists.

Professional Applications & Engineering Value

This Grade 5 zinc-plated steel carriage bolt is engineered to address common challenges in industrial settings, such as vibration-induced loosening and corrosion. The square neck integrates seamlessly into pre-drilled holes, locking the bolt in place to prevent spinning during torque application—ideal for structural frameworks, machinery assembly, and transportation equipment. Its UNC coarse thread design facilitates rapid installation in wood or metal, while the zinc plating offers a protective barrier against moisture and chemicals, extending service life in outdoor or corrosive environments. With a high tensile strength of 120,000 PSI, it supports heavy loads in construction and manufacturing, reducing downtime and replacement costs. This bolt is a reliable choice for engineers seeking durability, compliance, and efficiency in industrial carriage bolt applications.
