Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
- Secure anti-rotation locking provided by the square neck design, preventing bolt spin during installation and vibration
- High tensile strength of 60,000 psi ensures reliable performance in heavy-duty structural and construction applications
- Excellent hardness (Rockwell B70) maintains thread integrity and fastener durability under high stress
- Wide rounded head profile distributes clamping force evenly, reducing surface damage and improving load distribution
- Coarse UNC threading allows for faster installation and better performance in wood and soft materials
- Full threading provides maximum grip length and flexibility for various material thicknesses
Professional Applications & Engineering Value
This zinc-plated steel carriage bolt is engineered to solve critical challenges in industrial fastening applications. The square neck design effectively prevents rotation during torque application, eliminating the need for secondary locking mechanisms in wood-to-metal connections and structural framing. The Grade 2 strength classification combined with 60,000 psi tensile strength ensures reliable performance in heavy construction, trailer manufacturing, and agricultural equipment where vibration resistance is paramount. The zinc plating provides essential corrosion protection for outdoor applications, while the coarse UNC threading facilitates quick installation in timber, structural steel, and composite materials. These carriage bolts deliver exceptional value in applications requiring both security and corrosion resistance.
Specification Summary & Compliance
