- High tensile strength of 70,000 psi ensures reliable load-bearing capacity for heavy-duty industrial applications.
- Wide rounded head profile distributes clamping force evenly and reduces surface damage.
- Coarse UNC threading allows for faster assembly and better performance in wood and soft materials.
- Class 2A thread fit provides consistent, reliable engagement with standard nuts and tapped holes.
- Full threading offers versatile fastening options along the entire bolt length.
Professional Applications & Engineering Value
This heavy-duty carriage bolt is engineered to solve critical fastening challenges in demanding environments. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for marine, construction, and chemical processing applications where moisture and chemicals are present. The square neck under the rounded head locks securely into materials, eliminating rotation during tightening and vibration, which is essential for structural assemblies, trailer beds, and machinery frames. With UNC coarse threads and Class 2A fit, it ensures quick, reliable installation in wood, metal, and composite materials, reducing assembly time and maintenance costs. Its high tensile strength and Rockwell B55 hardness guarantee long-term durability, supporting safety and performance in industrial and agricultural equipment.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit and adheres to UNC coarse thread standards with a size of 5/8"-11. It is manufactured in compliance with ASME B18.5 specifications for dimensional accuracy and performance. Additionally, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for global industrial use.
