S-93180A682 1/2"-13 x 9" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications.
• Superior anti-rotation performance thanks to the integrated square neck that locks securely into materials during installation.
• High tensile strength of 70,000 psi and Rockwell B55 hardness for reliable, heavy-duty load-bearing capabilities.
• Secure and rapid fastening with the coarse 1/2"-13 UNC thread and Class 2A fit, ensuring consistent engagement.
• Optimized for industrial use with a wide, rounded carriage head design that provides a larger bearing surface and resists pull-through.
• Regulatory compliance with ASME B18.5, RoHS 3, and REACH, guaranteeing material safety and manufacturing consistency.
• Versatile partial threading allows for a non-threaded shank section, providing enhanced shear strength where needed.

Professional Applications & Engineering Value

This 316 Stainless Steel Carriage Bolt is engineered to solve critical challenges in structural and industrial fastening. The square neck design prevents rotation during torque application, eliminating the need for secondary locking mechanisms and speeding up assembly in wood, metal, and composite structures. Its UNC coarse thread and Class 2A fit ensure quick, reliable installation even in materials prone to minor misalignment. The partially threaded configuration provides an unthreaded shoulder, offering superior resistance to shear forces and vibration in demanding applications such as construction, transportation equipment, and marine fixtures. The wide rounded head distributes clamp load effectively, reducing surface damage and maintaining joint integrity under dynamic loads.

Specification Summary & Compliance
