S-92356A176 3/8"-16 x 18" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and outdoor applications
• Exceptional tensile strength rated at 70,000 psi for reliable performance in heavy-duty and structural applications
• Secure anti-rotation locking provided by the square neck design, preventing bolt spin during installation and use
• Optimized coarse threading (3/8"-16 UNC) ensures faster assembly and better performance in softer materials
• Precision thread fit (Class 2A) guarantees consistent engagement and reliable fastening in industrial settings
• Wide, rounded head profile distributes load effectively and provides a finished appearance while reducing surface damage
• Full regulatory compliance with ASME B18.5 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This heavy-duty carriage bolt delivers critical engineering solutions for demanding industrial applications where both strength and corrosion resistance are paramount. The 18-8 stainless steel composition provides excellent protection against rust and chemical exposure, making it ideal for construction, marine, and food processing equipment. The square neck design effectively prevents rotation during torque application, eliminating the need for secondary locking mechanisms and reducing installation time. With 3/8"-16 UNC coarse threading and Class 2A thread fit, this bolt ensures rapid assembly and reliable performance in wood, metal, and composite materials. The partially threaded shank concentrates strength where needed most, while the 18-inch length accommodates substantial material thickness in structural frameworks, trailer manufacturing, and heavy machinery assembly.
