• Enhanced anti-rotation security through integrated square neck design that prevents spinning during installation and use
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and structural stress
• Optimized thread engagement with UNC coarse threading and Class 2A fit for faster assembly and reduced cross-threading risk
• Wide rounded head profile provides larger bearing surface for improved load distribution and reduced surface damage
• Partial threading design allows for precise clamping force control in wood-to-metal and structural connections
• Full regulatory compliance with ASME B18.5 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This 12" carriage bolt delivers exceptional engineering value for demanding industrial applications where corrosion resistance and structural integrity are paramount. The 316 stainless steel composition provides superior protection against saltwater, chemicals, and atmospheric corrosion, making it ideal for marine installations, wastewater treatment facilities, and coastal construction projects. The square neck design effectively prevents rotation during torque application, eliminating the need for secondary locking mechanisms and reducing installation time. With its partially threaded configuration and UNC coarse threads, this bolt ensures optimal clamping force in wood, structural steel, and heavy timber connections while maintaining ASME B18.5 dimensional standards for reliable interchangeability across industrial applications.

Specification Summary & Compliance

This heavy-duty carriage bolt features precise Class 2A thread fit with 1/2"-13 UNC coarse threading and meets dimensional requirements per ASME B18.5 specifications. The product maintains compliance with environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring suitability for regulated industries. Manufacturing consistency is verified through material hardness of Rockwell B55 and mechanical performance rated at 70,000 psi tensile strength.
