Professional Applications & Engineering Value
This zinc-plated steel carriage bolt is engineered to address common challenges in industrial assembly, such as vibration loosening and corrosion. The knurled neck grips securely into materials, preventing spin-out during torque application, which is critical in wood-to-metal and structural framing applications. Its Grade 2 strength and 60,000 PSI tensile strength provide a robust fastening solution for agricultural equipment, trailer manufacturing, and construction projects where coarse UNC threads facilitate quick installation in softer materials. The zinc plating offers a protective barrier against rust, extending service life in outdoor or humid conditions, making it a versatile choice for heavy-duty industrial fastening that demands both performance and compliance.
Specification Summary & Compliance
This carriage bolt features a 1/4"-20 UNC coarse thread with a Class 2A thread fit for standard dimensional accuracy and easy assembly.
