S-90185A132 7/16"-14 x 1 1/2" ASME B18.5, SAE J429 Carriage Bolts

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 120,000 psi tensile strength, ideal for high-stress structural connections
• Superior corrosion resistance through black-oxide steel coating, extending service life in harsh environments
• Secure anti-rotation performance with integrated square neck design that prevents spinning during installation
• Optimized thread engagement through UNC coarse threading and Class 2A fit for faster assembly and reliable holding power
• Enhanced durability with Rockwell C25 hardness, maintaining structural integrity under repeated stress
• Broad compatibility with standardized 7/16"-14 thread size and ASME B18.5 specifications for interchangeable use
• Environmental compliance meeting RoHS 3 and REACH standards for sustainable industrial applications

Professional Applications & Engineering Value

This Grade 5 carriage bolt delivers critical engineering solutions for heavy-duty fastening applications where vibration resistance and structural integrity are paramount. The black-oxide steel construction provides superior protection against rust and corrosion in outdoor or high-moisture environments, while the fully threaded UNC coarse spacing ensures rapid installation and maximum thread engagement in wood, metal, and composite materials. The integrated square neck mechanically locks into assembled materials, eliminating rotation during torque application - a crucial feature for structural framing, trailer manufacturing, and agricultural equipment where safety depends on secure, non-loosening connections. Engineered to ASME B18.5 standards, these carriage bolts maintain dimensional consistency for reliable performance in construction, transportation, and industrial machinery applications.
