• Wide, rounded carriage head provides a larger bearing surface for enhanced load distribution and a finished appearance.
• Coarse UNC threading and full threading along the 4" length allow for faster installation and easier engagement in various materials.
• Precision Class 2A thread fit ensures consistent, reliable mating with nuts for a secure assembly.
• Compliance with major industry standards including ASME B18.5, RoHS 3, and REACH, guaranteeing quality and environmental safety.

Professional Applications & Engineering Value

This heavy-duty carriage bolt is engineered to solve critical challenges in construction, machinery, and structural assemblies. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications exposed to moisture, chemicals, or weather elements. The defining square neck under the rounded head bites into the material upon installation, effectively preventing spin-out and eliminating the need for additional locking mechanisms. This feature is invaluable in wood-to-metal fastening, trailer building, and framework where vibration resistance is paramount. Combined with its coarse UNC thread and fully threaded design, it offers quick, deep penetration and a strong hold in wood, steel, and other substrates, streamlining assembly processes and enhancing the longevity of the final product.

Specification Summary & Compliance

This 3/4"-10 UNC carriage bolt features a Class 2A thread fit for standard tolerance and reliable assembly.
