• Enhanced durability backed by Rockwell B55 hardness for long service life
• Regulatory compliance meeting ASME B18.5, RoHS 3, and REACH standards

Professional Applications & Engineering Value

This 316 stainless steel carriage bolt delivers critical performance advantages for industrial applications where corrosion resistance and structural integrity are paramount. The square neck design prevents rotation during installation, eliminating the need for secondary locking mechanisms in wood, metal, and composite assemblies. With partial UNC threading and Class 2A thread fit, it provides optimal engagement in coarse-grained materials while maintaining precise dimensional accuracy. The combination of 70,000 psi tensile strength and Rockwell B55 hardness ensures reliable performance in structural connections, marine environments, chemical processing equipment, and outdoor infrastructure where exposure to moisture, chemicals, and temperature variations would compromise inferior fasteners.

Specification Summary & Compliance

Manufactured to ASME B18.5 specifications with Class 2A thread fit tolerance for consistent performance. Features 1/2"-13 UNC coarse threading with partial threading configuration and right-hand thread direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
