- High tensile strength of 70,000 psi ensures reliable fastening in demanding structural and industrial applications
- Wide rounded head profile (1.344") distributes load evenly, reducing surface damage and improving joint integrity
- Coarse UNC threading with Class 2A fit allows for quick installation and easy alignment in wood and metal assemblies
- Full threading along the 2-1/2" length provides flexibility in nut placement and accommodates varying material thicknesses
- Compliance with industry standards including ASME B18.5, RoHS 3, and REACH, ensuring safety and environmental responsibility
Professional Applications & Engineering Value
This 5/8"-11 UNC carriage bolt is engineered to address common challenges in heavy-duty fastening, such as vibration-induced loosening and corrosion in outdoor or high-moisture settings. The 18-8 stainless steel material offers excellent resistance to rust and chemical exposure, making it suitable for construction, agricultural machinery, and marine applications. The combination of a square neck and wide rounded head ensures secure, anti-rotation performance in wood-to-metal connections, while the coarse thread design facilitates faster assembly in coarse-grained materials. With a Rockwell B55 hardness and 70,000 psi tensile strength, it provides dependable load-bearing capacity, reducing maintenance needs and downtime in industrial operations.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit with 5/8"-11 UNC coarse threading and a right-hand thread direction. It meets ASME B18.5 dimensional standards and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to global manufacturing requirements.
