S-92356A193 5/8"-11 x 10" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior anti-rotation performance with a square neck design that locks securely into materials, preventing spinning during installation and use.
• Excellent corrosion resistance provided by 18-8 Stainless Steel, ideal for harsh or outdoor industrial environments.
• High tensile strength of 70,000 psi ensures reliable load-bearing capacity and structural integrity in demanding applications.
• Rockwell B55 hardness offers enhanced durability and resistance to wear and deformation over time.
• Coarse UNC threading with Class 2A fit allows for faster installation and easier alignment in various materials.
• Partially threaded design provides a smooth shank for better clamping force distribution and secure fastening.
• Wide, rounded carriage head distributes pressure evenly and offers a finished appearance while reducing surface damage.

Professional Applications & Engineering Value

This heavy-duty carriage bolt is engineered to solve critical fastening challenges in construction, machinery, and structural assemblies. The 18-8 Stainless Steel material ensures long-term reliability in corrosive or high-moisture settings, such as agricultural equipment, marine fixtures, and outdoor frameworks. Its square neck design is a key engineering feature that bites into wood or metal, eliminating rotation during torque application and maintaining alignment under vibration. The partially threaded configuration and coarse UNC thread facilitate quick installation in coarse-grained materials, reducing assembly time while providing a secure, vibration-resistant connection. With a 10" length and robust build, it is ideal for heavy-load applications where anti-rotation performance and durability are paramount.
