• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing performance
• Effective anti-rotation security through the square neck design that prevents spinning during installation and use
• Optimized thread engagement with partially threaded UNC coarse threading for faster assembly and reduced cross-threading risk
• Precision manufacturing with Class 2A thread fit ensuring consistent performance and compatibility with standard nuts
• Regulatory compliance assurance meeting ASME B18.5 standards plus RoHS 3 and REACH environmental regulations
• Versatile 16-inch length providing ample reach for heavy-duty fastening applications across multiple materials

Professional Applications & Engineering Value

This heavy-duty carriage bolt delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The 18-8 Stainless Steel composition provides exceptional corrosion resistance for outdoor structures, marine environments, and industrial settings exposed to moisture and chemicals. The square neck design fundamentally solves rotation issues during torque application, maintaining alignment in wood-to-metal and structural steel connections. With 3/8"-16 UNC coarse threading and Class 2A thread fit, installation efficiency improves significantly while maintaining secure fastening in construction equipment, trailer assemblies, and agricultural machinery. The partially threaded configuration concentrates strength where needed most, preventing thread damage in through-hole applications.

Specification Summary & Compliance

This carriage bolt features precision 3/8"-16 UNC coarse threading with Class 2A thread fit tolerances, ensuring reliable engagement with standard nuts. Manufacturing complies with ASME B18.5 standards for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for regulated industries and international markets requiring environmental compliance certifications.
