• Optimized thread engagement with UNC coarse threading and Class 2A fit for faster assembly and secure fastening
• Enhanced durability with Rockwell B55 hardness, providing excellent resistance to wear and deformation
• Secure partial threading allows for precise clamping force control while maintaining unthreaded shank strength
• Full regulatory compliance with ASME B18.5, RoHS 3, and REACH, ensuring safety and environmental standards are met

Professional Applications & Engineering Value

This 3/8"-16 UNC carriage bolt delivers critical engineering solutions for industrial and construction applications where vibration resistance and long-term reliability are paramount. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for outdoor structures, marine environments, and chemical exposure areas. The square neck design securely locks into materials, preventing rotation during torque application—a common failure point in dynamic load scenarios. With its partially threaded configuration and coarse UNC threading, it offers faster installation in wood, metal, and composite materials while maintaining high tensile strength for structural connections. These features make it ideal for heavy equipment, trailer assemblies, scaffolding, and architectural frameworks where safety and durability cannot be compromised.

Specification Summary & Compliance

This carriage bolt maintains precise Class 2A thread fit per UNC standards with a minimum thread length of 1". Manufacturing and dimensional specifications strictly adhere to ASME B18.5 standards. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial applications.
