- Reliable tensile strength of 60,000 psi and Grade 2 classification, providing dependable load-bearing capacity for structural applications.
- Optimized thread engagement with UNC coarse threading and Class 2A fit, facilitating faster assembly and reducing cross-threading risks.
- Robust material hardness rated at Rockwell B70, offering excellent resistance to wear and deformation under stress.
- Versatile partial threading allowing for secure clamping across varying material thicknesses without compromising grip.
- Compliance with major industry standards including ASTM A307 and ASME B18.5, ensuring consistent quality and interoperability.
Professional Applications & Engineering Value
This hot-dipped galvanized steel carriage bolt is engineered to address critical challenges in heavy-duty construction, agricultural machinery, and infrastructure projects. The square neck design effectively counters rotational forces, eliminating the need for additional locking mechanisms and speeding up assembly in timber or metal frameworks. Its Grade 2 strength and 60,000 psi tensile capacity make it ideal for load-bearing connections, while the galvanized coating provides a durable barrier against rust and chemical exposure, extending service life in outdoor or high-moisture settings. The partially threaded configuration with UNC coarse threads ensures secure fastening in dynamic applications, reducing maintenance downtime and enhancing structural integrity.
Specification Summary & Compliance
This carriage bolt features a 3/4"-10 UNC coarse thread with Class 2A tolerance for precise fit, a minimum thread length of 6 inches, and complies with ASTM A307 and ASME B18.5 manufacturing specifications. It is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations for industrial use.
