Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with Grade 5 classification and 120,000 psi tensile strength for reliable performance in demanding applications.
- Secure, non-rotating installation thanks to the integrated square neck that locks into materials, preventing spin during tightening.
- Enhanced corrosion resistance from the black-oxide steel finish, prolonging service life in various industrial environments.
- Optimized thread engagement with fully threaded UNC coarse pattern for faster assembly and stronger holding power.
- Superior mechanical durability ensured by Rockwell C25 hardness, reducing wear and deformation under stress.
- Wide, rounded carriage head design distributes clamping force evenly and provides a finished appearance.
- Broad compatibility with coarse-threaded components and standard tools, streamlining maintenance and repairs.
Professional Applications & Engineering Value
This Grade 5 carriage bolt is engineered to address common fastening challenges in heavy-duty industrial and construction settings. The black-oxide steel construction offers a protective layer against rust and abrasion, ideal for outdoor machinery, structural frameworks, and agricultural equipment. The square neck design eliminates the need for additional anti-rotation hardware, simplifying installation in wood, metal, or composite materials. With a fully threaded UNC coarse thread, it ensures rapid, secure fastening in high-vibration environments, reducing the risk of loosening. Its 120,000 psi tensile strength and consistent Class 2A thread fit provide reliable clamping force, making it a go-to solution for load-critical assemblies where safety and longevity are paramount.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional standards, including Class 2A thread fit for consistent engagement and UNC coarse threading (5/8"-11). It meets ASME B18.5 specifications for dimensional accuracy and performance. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
