• High tensile strength of 70,000 psi delivers reliable load-bearing capacity for demanding structural and heavy-duty applications.
• Optimized thread engagement with UNC coarse threading and Class 2A fit, enabling faster assembly and reduced cross-threading risks.
• Durable mechanical performance backed by Rockwell B55 hardness, resisting wear and deformation under stress.
• Versatile partial threading design allows for secure clamping in materials where full threading isn't required, offering application flexibility.
• Compliance with industry standards including ASME B18.5, ensuring dimensional accuracy and interchangeability in professional settings.

Professional Applications & Engineering Value

This 5/8"-11 UNC carriage bolt is engineered to address critical fastening challenges in industrial and construction sectors. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor machinery, agricultural equipment, and marine applications. The square neck design securely locks into wood or metal, preventing rotation during torque application and vibration, which is essential for structural assemblies like trailer beds, framing, and heavy timber connections. With a partially threaded shank and coarse UNC threads, it ensures quick installation and strong holding power in soft materials, reducing labor time and improving project efficiency. Its high tensile strength and Rockwell B55 hardness further ensure durability under dynamic loads, offering long-term reliability in demanding environments.

Specification Summary & Compliance

This carriage bolt adheres to precise dimensional standards with a Class 2A thread fit and UNC coarse threading (5/8"-11), ensuring consistent performance and easy replacement. It meets ASME B18.5 specifications for carriage bolts, guaranteeing manufacturing quality and interchangeability. Additionally, the product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, supporting sustainable and safe usage in global markets.
