S-92356A650 3/8"-16 x 7" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to 18-8 Stainless Steel construction, ideal for harsh environments and outdoor applications.
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable performance under heavy loads.
• Effective anti-rotation security provided by the integrated square neck, preventing the bolt from spinning during installation and use.
• Optimized for quick assembly with UNC coarse threading and a partially threaded design, reducing installation time in wood and metal applications.
• Enhanced durability and longevity from the rounded head profile, which distributes stress and resists embedding in softer materials.
• Guaranteed dimensional accuracy and interchangeability, manufactured to meet precise ASME B18.5 standards.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental regulations.

Professional Applications & Engineering Value

This heavy-duty carriage bolt is engineered to solve critical fastening challenges in demanding industrial and construction settings. The 18-8 Stainless Steel material offers excellent resistance to rust and corrosion, making it suitable for outdoor structures, agricultural equipment, and marine applications where moisture is a concern. The square neck design is a key engineering feature that locks securely into materials, eliminating rotation during torque application and preventing loosening under vibration—a common failure point in machinery and structural assemblies. With its 3/8"-16 UNC coarse thread and partially threaded shank, it ensures rapid installation and strong holding power in wood, metal framing, and conveyor systems. This bolt delivers reliable, long-term performance, reducing maintenance needs and downtime in industrial fastening applications.
