• Regulatory compliance assurance meeting ASME B18.5 specifications and environmental standards (RoHS 3, REACH)

Professional Applications & Engineering Value

This heavy-duty carriage bolt delivers exceptional engineering value through its 18-8 stainless steel composition and precision manufacturing. The square neck design addresses critical anti-rotation challenges in structural applications, preventing bolt spin during torque application and ensuring secure fastening in wood, metal, and composite materials. The fully threaded UNC coarse threading enables rapid installation while maintaining superior pull-out resistance, making it ideal for construction, agricultural equipment, and industrial machinery where vibration resistance is paramount. The combination of 70,000 psi tensile strength and corrosion-resistant properties ensures long-term reliability in outdoor and high-moisture environments, reducing maintenance frequency and replacement costs.

Specification Summary & Compliance

This 5/8"-11 UNC carriage bolt features precise Class 2A thread fit tolerances and complies with ASME B18.5 manufacturing standards. The inch-dimensioned component maintains exacting specifications including a 1.344" head diameter, 0.344" head height, and 0.64" square neck width. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use across industrial sectors while meeting international quality benchmarks for heavy-duty fastening solutions.
